How To Pick The Best LED Grow Lights


led grow lightWith so many different LED grow lights how do you know which company to go with? This is the question faced by many newbie LED growers. Adding LEDs to your grow room can be a very wise decision and the results will be very rewarding if you get a high performance light and go with a company who can provide top notch service whenever needed. We researched countless number of LED grow light companies and provided our results here. Each of these companies have several different products. We chose the medium sized lights from each company and tried to pick lights that are similar to each other in terms of coverage area and performance to give you an apple to apple comparison.

  1. California Lightworks – http://californialightworks.com/

A Company out of Southern California that sells top-tier lights which feature a combination of diodes and UVB fluorescent tubes. Performance of their lights are in line with their advertised specifications. Their line of Solar Storm lights can be found on several different sites.

  1. G8LED – http://www.dormgrow.com

Another California company that sells the G8LED brand and is know for very high customer service and their Optimal 8-Band technology. Their lights produce large yields and have a very efficient design. They offer very competitive pricing and high customer and product feedback ratings.

  1. Advanced LED – http://www.advancedledlights.com/

One of the original LED grow light companies sells their popular Diamond Series grow light which feature optical lenses to concentrate light to a narrower space. The Diamond Series lights have been one of the favorites in the LED market and continue to be a top tier grow light.

Although there are several other companies with good products, our research narrowed the search to these top tier companies. We have been following LED grow lights for several years and find that many companies are only around for just a few years and then disappear. This adds a layer of risk for the consumer so it is important to go with a company that will be around to provide service if and when needed. We have summarized our top picks below:


Item SolarStorm 440 G8-450 + 90W Red DS-300
Company Cal Lightworks G8LED Advanced LED
Coverage 3’x3′ 4’x3′ 3’x3′
Veg Wattage 235 280 208
Flower Wattage 320/350 360 274
Diode Size 5W 3W 3W
Price $899 $599 / $749 $795

  1. I used this comparison website which includes up-to-date 2016 information : ledplantlights.com

  2. With the improvements in the new lighting technology available in 2016 it probably makes sense to upgrade your outdated inefficient lights from yesteryear.

  3. I think having a LED grow light for you is a good alternative to be taken but I must say while picking up the best one for yourself you need to take care of some of the aspects which are mentioned in the above post. I really think one must try to adhere the various aspects by visiting: http://gro-kart.com/. I am sure that will be beneficial for sure.

  4. Before going to buy an LED light we should careful about so many things that the lights are manufactured from a good company, whether the lights are certified or not, etc. The above post is all about that and this will definitely helpful to the buyers. I would like you to visit: http://www.ledtubelighting.com.au/ for highest quality LED tube lights at the most competitive prices.

  5. they advertise that they are full spectrum 54000 lumens they say their 750 watt will replace 2000 watt hid light and that their 300 watt will replace 1000 watt hid light

  6. their site keeps popping up just wondering if anyone has tested their led lights initial-led.

  7. Also in the same class — the P600 from PlatinumLED. From their website it says it’s at 184w veg, 368w bloom, but more than $100 less expensive than Advanced.

  8. Warning: i just went to 420mag to review the commented sources. Kaspersky gave me a warning that the page contains a Trojan. FWIW

  9. Sorry dude about your experience, but the conclusions that you have drawn from them are completely WRONG! I have been using LED for both veg & bloom for almost a year with great results. It really depends on the manufacturer and their understanding of LED design to meet the unique needs of the mmj farmer. The attached link is a example grow with lots of pictures that are grouped by date taken. This is EXACTLY the lights that I use in EXACTLY the same setup, and i have experienced EXACTLY the same or better results than the great results they are showing in those pictures. For instance, I currently have 3 Maui-Skunk mothers that I am flowering as it was time to let them go with two TruLight 440’s hovering over them at a distance of 16 inches from the canopy. I am in week 8, there are two more weeks to go, and I can easily estimate that I have at least 2 to 2.5 pounds of future dry meds (using a 70% reduction from the estimated current wet weight) right now and could easily finish closer to 3 pounds since I have two weeks left.

  10. You are misinformed and should stop propagating false information. There’s numerous fallacies in your comment that I don’t have time to break down. Here’s two of them though: LED’s aren’t measured with lumens since they only produce spectrum relevant to plants and not all in the visible spectrum. HPS may produce 80k lumens but much of that will be “wasted” on useless spectrum that are irrelevant to your plants. So comparing MH/HPS to LED based on lumens is a waste of time. Instead figure out what spectrums matter and see which light technologies hit those spectrums the best and consider the pros and cons of all the other factors. The other dumb thing you said was that LED loses light over time… LED is the most efficient light source, period. It will degrade far slower than MH or HPS by a LARGE margin. Many LEDs are rated in the 50k-100k hours. Please check my sources for more info.



  11. I tested LED grow lights and i can confirm you that LED is still way below HPS lightning for flowering stage….

    FOR vegetative stage LED is great !
    FOR flowering stage LED sux !

    If you want to have real good buds then HPS is must for flowering stage and never use HPS 150W…minimum is 250W and best results start at 400W and more
    I was wrong thinking that HPS is problematic because of temperature, point is that photosynthesis is at its peak at 29-31C and LED can’t delivered enough lumens and temperature ! So buds will never be big and potent like in HPS. NEVER !

    Don’t loose time and money trying to achieve results like in HPS !

    LED are too expensive, over time they loose output power of light (lumens)
    When i buy my first led light i test them how much electricity they spent…using them 2 years i see electricity drain from 140W to 100W. LED light can’t penetrate like HPS and they have lower lumens…

    HPS is still better then led

  12. Don’t hate because of my yields. I have had bigger yields on my outdoor grows too. I haven’t documented my grows thus far but will start on my current grow and share with you guys.

  13. The Grim Reefer on

    You could have linked us to proof of your yields, I call bullshit on you and your bogus statements. Your just another blogger for these over priced lights that do not deliver. Somethings rancid indeed!

  14. Humboldt Billy on

    Sorry but I doubt the yields you are claiming, I have yet to see any proof anywhere on the the web or youtube that back up these kinds of claims. Please show me proof and I will admit I am wrong.

  15. Do people experience shading issues at the base of the plants due to led being to narrow of a spectrum. Also is LUX and PAR relative. Like stronger strains from higher light intensity. Sorry, I do advanced reef keeping but i do not know much about growing plants using artificial light.

  16. i’m using the larger G8LED lights – G8-900 for over a year now and never had any issues with the light
    I love not having to deal with the heat..it runs amazingly cool for such a large light and i get killer yield anywhere from 5-8oz per plant, 8-12 plants per light depending on strain and growing methods. Lush is good too, my friend has one but i always yield more than him

  17. Good for vegetative, All of these brands come nowhere close to standard HPS. I have a large budget given to me by the people that I grow for in CA. I have used these brands as well as a few more. All these lights burn out if run at full power. Cost has not been a factor but yield is for us. Everyone save your money, maybe in a few more years LED will equal HPS

  18. The science in this article is so overwhelming, i may need to go back to college to understand it.
