This is our first use of a light controller. So far so good.

I would say its not entirely intuitive, and honestly haven't figured it out in its entirety. I've heard the youtube video helps a ton on that, just haven't had the chance to dig into it too far.

I do like it, lights run much warmer than our others which has required some adjustment.

if your looking for an amazing light this is it. perfect for 3x3 or 4x4 grow tents. I’ve been growing indoors for decades. This light is hands down the best light out of many i have owned. you will notice a difference in your plants immediately.

the quality is good and so bright. My 1st light has been going for 3 years and is just as good, far better than any of china LED on amazon.

SolarSystem® UVB Kit

I use 3 of these over a 4 x 8 area. One light is hang underneath each (in the middle of the led rack where no leds are) of two Gavita 17oos. The third is in the middle between the two led racks. The reason is terp enhancement. On for two hours during mid light cycle the last three weeks of flower.

SolarSystem® 550

Best controller out there and it works with the new lamp also

I love this light and so do my plants.
I didn’t know what to expect when ordering from California light works. I gave it a try and extremely happy with the product. I would like to try some more their products when I’m ready to upgrade my other lights.

Awesome light brightens my whole grow room.

I researched this company for a couple of weeks before deciding on the 500 and I had no idea what I was in for. Now I am upgrading the rest of my setup to accommodate the power of this light. Quality product, built well and one of the brightest LED lights I have ever seen. The fans run quiet, the heatsink works as intended, overall a top notch light, I highly recommend.

This is the second one of these that i've purchased, i got a fluence spydr between them, but the fluence ballast are crap, soo i decided to stick to what has worked.

Am thoroughly impressed by how light has performed over last 3 weeks. My initial experience of led lights was from those led ufo lights decade and a half ago, there has been an amazing amount of advancements in those years. Switching from 400 watt hps light to the solar extreme 500 I am very happy with it. Quality of build is impressive. Will have to see how flower goes for final assessment.

Have not used yet

I was gifted a 1100 solar system light with the controller. There was problems with the controller. CLW worked with me to try & fix it, but it didn't work. I received a discount & purchased a new one. No more problems. Thanks CLW.

I just got this Spectramax 1000
I already see a marked improvement on bud development down at the lower levels of the plant!
I have bought knockoff LED lights they look bright to me but they don’t produce buds like these lights do!
Thank you
