20 Best 300W Led Grow Light (2022 Updated)

This is the best & easiest-to-use 450W grow light with on/off timer I found to use in a 48″ x 24″ grow tent for my herb garden. Specs: 90 LED lights arranged in 3 groups of 5×6 Outputs 12 different light waves for full light spectrum good for all plant stages including seedlings/growing/veg/flower/fruit/etc.

120V A/C indoor use, draws about 210W when lights are on 100% brightness Has power output plug so you can daisy chain these together, but the timer on 1 unit doesn’t control other units plugged into it.

450W equivalent output compared to bulb or halogen lights Dimable from 100% down to 0% in 1% increments 2x 120mm fans on top and plenty of vent holes on all sides. Has 2 groups of light waves (VEG & BLOOM) and each group is independently dimable but both groups are controlled with the 1 timer so both groups must turn on and off together and can’t be turned on/off independently of each other.

It would be nice if they just made each group controlled with their own timer but unfortunately that’s not the case. yet. Includes 4x nylon coated steel cables with loop on one end and spring clip on other end for hanging the light.

They are each about 16″ overall length. This is a very easy-to-setup and use grow light that works for growing just about any plant at any stage of it’s life from seed to fully-grown. I got it because I didn’t want to buy a grow light along with a timer to control it along with a separate fan to cool it along with a power supply that adjusted to wattage.

This unit can be dimmed in 1% increments from 100% down to 0% for both light groups, it has cooling fans built in, and it’s built-in timer can be set to turn on once and off once per day, every day, like an alarm on your smartphone.

The LEDs are arrainged in 3 rectangular areas as you can see from the pics. The light is wide enough to perfectly cover a 30″ x 18″ grow tent. I have since switched to a 48″ x 24″ grow tent now and it still works fine for my herb garden but for perfect coverage I think using two 300W lights might give you a little more even coverage even though I haven’t noticed any of my herbs wanting to point inward instead of growing straight up so for me this light works perfectly well.

You can daisy chain multiple Viparspectra lights together, even if the other ones are not the same model as this one or do not have timer function. Unfortunately the timer on each light does not control any functions on any other lights you daisy chain from it, the daisy chain only allows power to be run in series to save you from running individual extension cords or taking up moreoutlets if you run a bunch of these lights.

For example you can daisy chain this light along with a 300W non-timer light, and 600W non-timer light together but the timer on this only controls this light’s on/off capabilities. The other 2 lights daisy chained to this will just stay on 100% of the time unless you have a separate control for them.

If you want a bunch of daisy chained lights to all turn on and off together then every model light must be the version with timer built-in like this one. The light output of this LED light is approx equivalent to a 450W halogen light but the LEDs are much more efficient which is why this light only draws about 210W at 100% brightness, and is also why it barely gets luke warm when it’s on.

I have been running my light at 40% power all day and it’s not even warm, it feels like it’s room temperature. The 2x 120mm fans on top of this unit produce some noise which most people don’t know how to measure and their interpretation of “loud” or “quiet” is hugely skewed because I see some reviews saying this unit “is so quiet” and others say “it’s very loud” but not everyone has perfect hearing so loud to me with great hearing could actually be silent to someone with very poor hearing.

Noise is measured in decibels (dB) and things such as a light breeze or breathing which can barely be heard is about 5-10dB, the average compuer fan is about 25-30dB, a conversation in a nice restaurant with low music in the background is about 50dB.

This unit sounds to me like it’s about 30-35dB, or slightly louder than the average computer fan running at 100% speed. Since it’s in the grow tent most of the noise is trapped inside so it sounds like about 15dB from the outside of the grow tent when it’s closed.

Controlling the VEG and BLOOM light groups independently is nice because you can control the different wavelengths your plant needs at different stages of it’s growth very accurately with this light.

I couldn’t find any specs on which of the 12 wavelengths are actually controlled by each setting though. The timer and remote are very handy because this light can be mounted out-of-reach and still be fully controlled with the remote.

So i write my first recension in my life, we’ll see. I’m not the kind of man who thinks in the past was all better, but in the future?, i don’t think all will be better. It always two faces. Now to the LED-Board.

I’ve got good onions and garlic grown with the Mars Hydro 2 900W. That Board is really good for 90cm tent, till today! The average was all the time really satisfactioned. But when you think it over, 10years go by, it must be made something new inventions in led technics, otherwhile it where stupid wasted time (or making much money).

So i collect informations at web, and i’ve seen, the time is ready for a new age of LED Boards. To many people said it’s amazing what’s invited already. And the Mars Hydro ST3000 is the right one for my 120cm tent, and my purse.

It’s like from dark to the light, can’t believe it. It’s totally quite, and the temperature is exactly nice warm over 20degrees. Now i don’t waste any power, it’s much better than the Hydro2 for the same power what would be putting out.

But you as a customer can use all the Hydro LED’s cheap and good at all, also everyone needs a second lamp, because of murphy’s law. I can’t send photos because no one want’s to see tomatoes at work! I’m the dude, believe me.

Really thanks to Mars Hydro, we stay tuned. And greest from my wife, she got all older lamps for growing cucumber!.

I have been putting off buying led lights for a long time, because the first one I bought 10-years ago, a Flying Saucer put off this ghastly pink light that hurt your eyes to look at it, so I went back to using a HPS.

This Viparspectra, is only slightly pink so you can actually work on your plants without the special glass’s. From what I’ve seen on Youtube more white LED’s are the future. My second concern was do they grew plants as fast as the HID lamps! A couple of years ago I bought this house with two acres of land, where they cut down almost every tree on the land.

Why people do this is beyond my understanding, so I’m in the process of turning it back into woodlands. I live next to a federal game preserve and wildlife abounds, so everything I plant if for the animals! This is the second one of these lights I’ve bought.

I bought one last October, and started some apple, cherry, maple, and oaks from seed keeping the light on 24/7, and even with trimming the trees several times, by march I had some nice bushy 4 foot trees, ready to plant in the spring.

Needless to say I’m impressed. Even though these lights are nowhere, near as bright as HID’s every plant I’ve grown under them so far seem to grow just as fast, and are more compact then under the HID’s with way less heat, soI bought another one for bushes, and flowers.

I can’t give them a 5 star because I haven’t had them long enough to judge how long they will last; but at the price it’s a great way to try LED’s!.

These things are pretty neat. The flex arms are perfect and hold their position well, though time will tell if that stays true. The lights are a bit weird, with the blue/red, and make the room look strange.

I wish it was just white. They are bright, however. The timer is okay, but only allows 3/6/12 hour settings, and you can’t pick the start time for them. Meaning, you press 6 hours, and 6 hours is then locked in to start at the moment you set it.

Some more functionality in the timer would be nice. However, in an apartment with no windows, these things are keeping my plants looking amazing through the winter, and I do not regret buying them. Upgrade the timer by just a bit, and it becomes a solid 5 star product.

Have recommended them to friends and family already.

I never bought a light for growing always regular light bulbs. Since getting this system I have seen significant changes in my grow. I like how it has the time and can set it how you like. It’s light weight and fills a tent all around.

It don’t get really hot but is super bright! I also think it’s cool that I can connect other lights together.

This is a great starter light for a great price. It beats out most other LED lights around the same price tag. I never really messed with the controller besides changing the light intensity as I have a outside timer to go with the schedule.

I look forward to them to continue making progress on these LED lights and maybe down the road have a little more output upgrades.

I bought two Grow Lights in October 2020. They were used indoors to keep my plants alive until March 2021 when they could go in our sunroom. Worked great and all made it through our cold dark winter.

Started up the lights again in late October 2021. Discovered one dead one this morning. A total of eight months out of the light. I expect the other to go out any day now. These are LED and should last far longer than eight months.

I will be switching to another brand of grow light for the rest of the winter.

I bought at least 6 grow lights during TG sale in 2019. I noticed half of them didn’t last long; 5-6 weeks. I don’t turn them on 24×7, only night time and sometimes I even forgot to turn on. Given how pricey it is and being LED which is supposedly last for a long time, I am disappointed with the quality.

Maybe I got bad ones because the other lights I bought lasted for at least over a year.

IšverstiShow in original languageI have owned some of the first generation of these lights. A friend of ours recently purchased a set of these,the first was a little longer shipping but he was informed his that this was a possibility? The second came with in a week of the first light.

These are a look at a true performance light I have seen that lights will be in the near future. Great system,no different than any AC Infinities products. As we grow older and wearable parts keep wearing! The circle of a growers life? If your just starting out,,,great products and for every growing lights,tents,and anything you have seen! We grow inside,I love the bag appeal on our product.

When I make with our old lights are still a more precision developed lights. This as I mentioned before,,every product AC Infinity has created or just made better you or friends will find these on the AC Infinity web site.

God Bless. The best part,,it won’t cost anyone a arm and leg purchase,there is those low balling stores,you know the kind that come and go?.

IšverstiShow in original languageThis light is kicking a m/h ts1000’s *** in a 3×3 side by side comparison! I have never seen a foot & a half fallen over stretched seedling stand back up on it’s own; wish I could show pics.

Not 1 plant has stretched that began under this S22 light; both tents are set at same heights, intensities, and maintained in corresponding environments. Plants moved under the S22 that stretched under the TS1000 have stood up, ceased stretching, and are LOVING this light! AC Infinity has the BEST customer service by far, so I feel great giving them my money; I cannot wait to buy their upcoming products!! Thank You AC Infinity!.

IšverstiShow in original languageAC infinity provides high quality at every single step. The tent is a step above, zipper, material, fan controller mount, everything works. The light is very pure WHITE.

The plants are thriving!! A great hanger setup on the ionboard, much better than others. I had the light installed in a few minutes, installing solo. AC infinity has my vote for great and best grow tent equipment.

Keep up the great work!.

It worked really good and it’s really bright white light lit up my room and I liked how bright it was but when I moved I was taking out the bulb and the twist in part stayed in the lamp. It broke. It worked really good before it broke.

:(.

Growing some herbs indoors to keep the isolation covid/winter blues away. Followed recommended instructions on the back of the package regarding seedlings (about 8″ above, at least 14 hrs light) along with covering the pots with plastic wrap/film to keep soil moist during germination process.

All the seeds sprouted around or under 5 days (twice as fast)! So far so good, will have to wait and see how well the seedlings grow.

I received these lights to replace bulbs in my can lights. When I used the lighting in my kitchen before these you could feel the heat from the floodlights almost immediately. These LEDs solved that problem completely.

I bought them to try in the kitchen and there was such a difference I ordered more so I can change the bedroom lights and the living room lights. They are smaller than the standard floodlight bulb but look fine, and are bright, perfect light.

These guys at Factorypure got me right, got my light for 50$ cheaper and the packaging was excellent

these lights are amazing for vegging plants i been using one to veg 10 easy.I just got another cant wait to see the growth rates.

Highly recommend! Definitely love the uv/iv build of this product, aswell as the dimming ability.

Switched from 1000w de to 4 1000w mars led lights uses just over half of the warts with the same results so far. Veg is equivalent to hid will change review if flower goes any different.

Lamp works well, very well! I had another 600w i bought. I put them together and put them to the test.

Runs cool good for seedlings,has no built in fans

Thank you ShopGrow. My light was delivered promptly great packaging no issues what so ever! This light is working out really well.

TraduireAfficher dans la langue originaleI’ve never been lucky with keeping plants alive. I have had several plants over the years and no matter how attentive I am to them they always die. I have never attempted to use grow lights so I had to do some research to figure out which color lights do what.

I have limited natural light in my home based on where the sun rises and sets and how my house is configured. I like that this has not only an adjustable timer but that I can also choose the between three light colors which all do different things.

The flexible arms make it easy to use this light for multiple plants and the clip or base option makes it easy to setup no matter how much or how little space you have. I’ll be interested to see if this will help me keep my plants alive.

TraduireAfficher dans la langue originaleWow ! This plant light is truly awesome. It is flexible in multiple ways. It has an adjustable timer that you can set for three , six or nine hours ! I love that feature.

You can also move it around easily because it can clip onto anything you want and it also is a stand. I have really enjoyed being able to move it around from different plants and vegetation that I am growing.

It has blue lights for vegetation growth and red lights for flowering growth. It also comes with a mounting bracket if you would like it to be stationary. This is a great replacement for any of the areas in your house that lack natural sunlight.

TraduireAfficher dans la langue originaleI was sent a Bell + Howell Growburst Light by the TryIt Sampling Community to use and review. I’ve always wanted to use grow lights indoors, but could never justify the cost if they didn’t work.

So I was very happy to receive and try this product. My house has limited windows, so I get hardly any light in many rooms for plant growing. This product was easy to set up and start. Plus the three separate lights make it easy to use it over several plants at a time.

The two best features are the adjustable timer and the color selection options. A very useful product that can be used year after year. I recommend it.

Great Light with high PAR output I rate the light 4 stars out of 5 only because they have to keep overhead low and prices down to keep a lock on the bottom tier lights. If you will note they will give no info or insight on the overall CCT “color” of the light overall.

These are great to get the job done for a cheaper price. I only wish they would start a panel light series with more IR and addition of UVB diodes would be great to make the lights better for flower than veg.

The only downfall to these lights. Due to the lack of UVA/B diodes and running the minimal amount of Red and IR extends the plants life cycle and makes it take longer to finish. Other than this, what keeps the price down, they’re really unbeatable.

Just don’t try to get than cct report ? Maybe it’s too far from optimal 3500k to mention. Or maybe R&D is slipping? either way buy, learn, practice and probably move on unless they start a new series.

I’m crossing my fingers and been asking them as well.

I have had several LEDs and Im really liking the full spectrum white lighting thats out. I also like the pinks. Hmm. I however went with a bar type setup for uniformity and because I didnt like the rectangular shape of the xs/p series 2500/4000 lights.

Had they been squared I probably would have stuck with them, but Im definitely not upset with the competition. There are some really good lights out there and I had to do a lot of research. great starter/veg light.

I still use it for vegetative gardening, but I use my Ze510(which is a steal) and supplemental lighting for fruiting. Amazing veg light. Good fruiting light. Would I buy it again – no. Would I recommend on a budget – absolutely.

Would I say save up or aim higher – honestly – most certainly. Im an honest type. some stiff competition out there with great rates and Love the friggin heat sink on this thing though. Great value item.

The top-line just isnt there on the higher end items compared to others.

Compared to other 2000W grow lights, this light had more LEDS than all the other lights I looked at. It has a dimmer knob so you can give the exact amount of full spectrum light to your plants. Comes with easily adjustable hangers.

My plants love the color of light that this grow light puts out. They have grown more in the first week since I’ve been using it than in two weeks of prior growth with my other light of the same wattage.

Worth the money!!!.

These grow lights are awesome. I bought five of them to put in different rooms for my plants. I have had other grow lights before and always found the light to be garish- even ones labeled as “warm white”.

This light emits a nice soft warm white light similar to a regular lamp, so you don’t feel like you don’t really want to be in the same room with it, like so many other grow lights. More importantly, my plants are loving it! My oxalis has filled out.

It’s lush and beautiful looking- and better yet, has started blooming on the side near the lamp. It has never bloomed on the side not facing the window in the five years I’ve had it! My various philodendron species, Sanseverias, Pepperomias, etc.

have all started pushing out lots of new growth since I started using these, and it’s only been a few weeks! I know these are more expensive than a lot of other grow lights, but they are sooo worth it.

I’ll never use anything else again.

The light is well made and simple, no controls or switches just power it on. It does produce some small amount of warmth when it is on, but nothing compared to my old 400W HID lamp which heated up my grow tent like crazy.

In the hot weather, LED is a must unless you want to spend hundreds on cooling. The fans that come with it are pretty quiet, but if you want you can replace them with any silent PC case fan (92mm). I replaced the mars 300 with this light as I got a bigger grow tent.

The results were pretty spectacular. By far the best quality and most effective LED light you can get for the price. Don’t worry about the more expensive lights, this one has all you need.

Really impressed with this product and my plants love it, for the price you will be hard pressed to find any other to beat it. When it arrived I plugged it into the meter results were as advertised, it has been running 18/6 with great results and fan noise is minimal.

My HID/HPS are packed away along with annoying ducting, now I have room to move. All in all I am happy I avoided the sceptic’s. Great people to order from and knowing their products are true as advertised.

Burnie.

Good Good Product. This LED is very powerful and can without a doubt compete with old HPS light. The price is amazingly low for the quality of the product. The possibility of remove the ballast to put them outside the tent change everything.

Highly recommended.

Happy with everything and all. My light came with a timely fashion and all. Just was wondering Where are the stickers went from inside the box it had none my other lights all came with them ? Just a thought thanks again !.

Company would replace light 32 days after purchase when half the light blew out. Wanted to trouble shoot by sending me parts. Better off getting a diy light for the same money or less. With better parts, and made in usa.

Everything arrived at time, nicely packed, the instructions are claer to understand. The tent is very easy to build and you must just plug in the lamp and it works. Simple and great!!! Thx Topledfactorystore :).

IšverstiShow in original languageAmazing lights things are growing great. Extremely happy with the quality. The only thing I would change is how the supplement bar is powered it seems to drain power from the other LEDs to power the supplement bar.

Resulting in an overall powerloss. Other then that great build puts out what is advertised.

IšverstiShow in original languageI bought this light to start a small vegetable farm in my guest bedroom since that won’t be used with COVID-19 going on. With the summer heat, and winter frosts lots of crops can only be grown outdoors during certain seasons.

Now with this light I have lettuce, kale, microgreens, potatoes, wheat grass, and carrots EXPLODING. Some plants I have under one of those $100 blue/red lights. The plants under this light are growing way faster and look way healthier! Definitely going to buy the SH2000 model next and attempt some indoor watermelon! Literally the best light on amazon, couldn’t be happier so far.

But just be warned I’ve only owned this light for a month so it’s still possible I’ll find an issue later on. but so far its AMAZING.

IšverstiShow in original languageI got two of these lights for starting vegetable seedlings and they have worked really well. My plants are healthy, green and not pale and leggy. The Spider Farmer lights have a bright white color that looks just like bright sunshine, and when I say bright, I mean BRIGHT.

I have them on a timer and while the weather recently has been dark and cloudy, every morning when the lights click on it is like a bit of sunrise coming through the doorway. One of the things I like is that these lights are completely silent — no cooling fan, no power supply whine, just bright light where I need it.

The only down side is that they are a little pricey, but if you can afford them and if you plan on using them for a long time they are well worth the cost. I would buy them again. Good job,.

Une bonne lampe de croissance qui n’est pas trop dispendieuse. Assez facile à installer, mais attention, si vos lampes sont de lots de production différents, les trous pour les vis ne seront pas tous à la même place! La lumière est très blanche sans être super éblouissanteni désagréable aux yeux, donc convenable dans les pièces à plusieurs fonctions.

Le cordon électrique a une bonne longueur, donc donne de la flexibilité pour l’installation. N’ayant pas de photomètre, je ne peux pas confirmer le taux de luminosité, mais je ne pense pas que c’est aussi puissant qu’indiqué sur l’emballage: en tout cas, le rayon de luminosité n’est pas aussi large qu’indiqué 2″x2″.

ce n’est pas un problème pour la plupart des plantes d’intérieur, qui en générale n’ont besoin qu’un supplément de lumière. Par contre, pour les semis, il faut s’assurer de les placer juste en-dessous de la lampe, au-delà de 15cm de chaque côté de la lampe, les semis s’étiolent.

Puisque les lampes ne sont pas super chères, le problème peut être réglé en mettant 2 lampes côte à côte pour les étagères de plus de 30cm de largeur.

C’est excellent pour commencer ses semis. Les plantes sont plus fortes, plus trapues Ils ne gaspillent pas leur énergie en cherchant de la lumière.

J’ai fait mes semis et je suis très surprise de la rapidité de croissance

This light is pretty sick for vegging purposes. Despite it being for a 4×4 tent. These are doing very well as a veg light in a 3×3 ac infinity tent. I’ve been using MH for vegging for over 12 years. Ballasts that fire up hortilux mh bulbs successfully every time is another topic lol.

So for me personally, once I get it to fire up, I leave it on 24/7. LED’s doesn’t have that problem and the spectrum and intensity on these board are pretty impressive. I can finally go on a 18/6 timer like everyone else and not have to worry about these turning on or not anymore lol.

For what you’re paying, I think these are actually stronger and better for overall growth and filling out space to even the edges of your tent. My only complaint is the short power cord it comes with.

It’s kind of silly actually. But other than that, no buyer’s remorse here.

Absolutely can’t fault these lights for the money, they’re very high quality. They put out a lot of light that covers a fairly wide area and they only sip electric compared to other alternatives, the coverage that these lights provide is good but not as wide as other alternatives however this hasn’t effected the growth of either my lettuce or my cabbage.

The setup is as easy as it comes, hang the light where you need it, plug it in and go! I would however like to see a built in timer function in future revisions, I’ve seen that they do remote controlled lights but I personally find it far too easy to put remotes down and forget where they are so an onboard timer would be fantastic and I don’t think it would bring the price up all that much.

This is more of a quality of life thing than anything else but it would’ve been a nice extra touch to an already fantastic product. The fans are somewhat noisy but given the heat they are dispersing it’s understandable, with that said they are very effective and I’ve never been concerned about how hot the unit has gotten.

If you’re looking at these and wondering if you should bite the bullet I absolutely recommend that you do, I have completely replaced my other lights with these and so far haven’t at all looked back.

The light has a lot of features found in much more costly grow lights. The company is very helpful and seem to care about you the customer. This can be a rare thing now days. Light will cover a 2. 5 foot square but no more.

Light runs cool only warm to the touch on the sides and top after running 24hrs for over a week. Fans are quit and remembers time and setting in a power lose. So if you happen to lose power you don’t have to worry your plants if you are not around when this happens.

Very cool, I was surprised the light did that. Has a dimmer for younger plants or sprouts and separate veg and bloom modes. Light does not seem that bright to me but the plants seem to like it and grow well.

I learned a lot reading the manual that came with it and would do that also. The only problem with the light I had was the battery was dead in the remote that came with it. If you push the switch on the light you can turn it off and on and just turn it to set modes.

That is not as easy as using the remote but nice if you loose or battery dies and you don’t have one on hand. I have been using the light for 5 weeks steady with no problems and am very happy with it.

Hope this helps.

I got one led to test out and then bought a second two weeks later. If you are someone who is looking into LEGAL cannabis cultivation, this light is great! I completed a full growing cycle before i came to post my review.

Some Tips: Seedlings/clones the light was best at 22-24 inches i left the light there and I would then let them grow “into” the light to about a distance 18-20 inches and maintain that until flowering cycle.

During flowering cycle i used both Veg and Bloom switches and let the plants grow to a distance 14-16 inches. Keep an eye on stretching during the first week or two of flower as you will need to adjust frequently, and these leds are strong so you don’t want to light burn your plants.

Heat is no issue but you do want good constant breeze on your canopy. I took a chance because there is not a lot of people who have experience with these lights with cannabis, but it well paid off.
