So far it grows but not outlandish results.

So far so good. This light gives great coverage in my 4x4 with almost zero shadowing.. the spacing between the diode strips is the perfect width to install the twin UVB bulbs to add some extra punch for finishing, which I love! I also added the controller to do sun up and sun down feature.. my only complaint is that you can’t adjust the spectrum bc it’s set from the factory. My only suggestion for improvement would be to allow the end user to control the spectrum. I wish I could crank up the violet for flower. But other than that it has been working great! My plants like it and you can tell the flowers are much tighter than HPS..

Was impressed with the packaging well secure. The light itself amazed me with how light it was makes it easy to move around. The light less then 5 min on i feel puts off alot of heat but it is alot of power so it makes sencce but I feel you would have to make sure your plants don't get to close or will burn them. I do not like the placement of the know to turn it on and adjustments its on the inside of the light bar instead of the outside I feel it is a bad placement overall so far so good no issues yet and plants seem to like it so far

This light is incredible! I have purchased and used almost every other grow light that California Lightworks manufactures. From the SolarSystem series, the MegaDrive Vertical, the SpectraMax, and now the SolarExtreme 820! Hands down the best light I’ve ever grown under. Amazing slim, sleek, solid construction, that delivers high yields and massive flower formations! And for the price, it’s absolutely insane! I wish I could post pictures, you would be blown away!

I have purchased and used quite a few lights over my years. So far this panel has exceeded my expectations both in performance and price..

I have purchased two of these lights now and plan to keep ordering more as my operation grows ! Huge yields and programmable controller ( sold separately) is easy to navigate and can hold several programs like veg, auto , flower …. Etc . The pulley system works great and and makes lowering and raising your lights a breeze . This light is super bright at 100 and maintains a manageable heat saving me moolah !! Ty ty Ty !

good stuff

This is my third light from California Lightworks - couldn’t be more pleased with its performance so far.

100 % satisfied with my purchase using it now will post results when grow is completed

Received light and controller everything looks nice and bright gonna put it to use soon but no complaints everything looks well built
