Exclusive Design of the Spectrum: The full spectrum is enhanced with blue and red light. The rich blue light promotes plant growth and the abundant red light improves the yield and quality of the plants.

Daisy Chain Dimming Feature: Dimming from 10 to 100% depending on the growth stage of the plant, while saving on electricity costs. The daisy chain can be connected to 30 lights at the same time from one master light.

Definitely an upgrade! I have to say these are the most amazing lights so far in my arsenal! All of mars hydro products are already starting to cover cutting edge technology, but these blow everything out the water! I have perfect coverage in a 4x4 area per light. I can run these through all stages with the dimmer and par map and ratchet straps. There is no down side to buying these lights! I want more!
Review by Rosie / (Posted on 1/20/2022)
Loving these lights!!!! they are treating my girls great and look badass while doing it! I'm really excited about the way things are going to turn out.
having the ballast attached to the outside of the tent will make a huge difference to this round!
very pleased with this product and they sent it to me like 3 weeks sooner than expected!
Review by Daisy / (Posted on 1/20/2022)
Great light does as advertised wished I had 2 more! Love the light. To add a little flash the company name should be colored. It would help stand out on video.
Review by jboth361 / (Posted on 12/21/2021)
Great light at a great price This is a great light for a 3x3 space and the price is affordable. It's easy to assemble, convenient removable driver, very bright, good penetration and easy to clean.
Review by Smokey / (Posted on 11/12/2021)
Well made & affordable like all of the Mars Hydro products I have used. This light is unlike any other ive used so far in my 3 x 3. It's so powerful it was like turning on the sun. It's so sleek and couldn't be easier to assemble. If you're wanting an amazing light that will give you excellent yields from your medicinal plants then look no further. I can not shout about this light enough....and for the price you just can't go wrong. Whether you're a beginner or pro it is the dogs clems.
It has the dimmer on the side and all the stuff you need to hang it. It's not heavy at all and one person can handle the job, easy. I have tried other competitors on the markets lights and they just don't compare and for me, I think they are more than enough for a 3 x 3 in a homegrown....sturdy, robust, gorgeous full spectrum, and very inexpensive for what you get...

Utterly empress!!! Perfect array and outstanding quality. Hands down best bang for buck/quality on the market
Review by Ge0terps / (Posted on 4/16/2021)
Great Value, saves money on the electric bill Just one month in and already have saved $75 on electricity on the first bill with just one HPS light replaced for just two weeks of the billing period. These light pay for themselves over my old HPS lights. And the plants LOVE them! Plus, the AC unit isn’t running full time!
Review by Gramps / (Posted on 4/9/2021)

Review by John I / (Posted on 3/22/2021)
good The combination of Samsung and OSRAM, in my opinion, is optimal in terms of price and quality.
Review by Kevin / (Posted on 3/9/2021)
Awesome light. Must have on a 3x3. My hot peppers love it. Great lights. Easy to set up. Glad I can put the driver on the outside. And I love the new addition to almost 400leds more than the previous version of this light.
