SolarSystem® UVB
Excellent Supplemental Lighting

There is definitely a noticeable increase in frost and coloration during the fade after putting this light alongside my Solar Extreme 500. I've come to expect excellent build quality and impressive results from California Light Works and this supplemental light is no different.

250 watt light

One of the best Cobb lights on the market, excided my expectations.

Spectramax 750

What a Great light. Very Bright light. I have it at 75% and it is plenty of light. Also using C.L.W. controller. Love Both products.

Outstanding quality of light

I am stunned by the results of this product... As a photographer, I liked "the look / feel", the quality of light, from the first time I powered up the SolarXtreme 500, it made sense to my senses... the plants [understandably] love it. I just ordered a SolarSystem 550 and controller... take the lighting options up a few notches. The 500 is great for general purpose (would like a few more), the 550+ctl will round out my options further, with UVB to follow...

**I have never had such success, uniformity, rapid growth ...from seedlings... with a type of "leaf loft", outward tips reaching towards the light, but plant remaining bushy, not becoming spindly.

I will never use another company for a LED fixture

Better then MH and HP

I purchased sx500 and uvb attachment got them on the 420 sale, 30% off only took like 4 days to get here. Everything works great when I need another light I'm buying it here, thanks for the great deal CLW

Love this light!

This light is everything I had hoped for and more. Glad I got the controller too, it's really a must have to get the most out of this light. Outstanding performance for my plants and I'm only two weeks into the grow cycle. Can't wait to see how she performs during flowering. Got a great deal on the 420 sale and couldn't be happier with my new California LightWorks SS550.


I have been growing auto flowers for years outside. Starting growing indoors and struggled with many lights until now. This light and controller are hands down the best. Auto's exploded with this combo. On my fourth run and still killing it. Will never buy another brand again.

SpectraMax 1000

Great product. Perfect for a 5x5 grow tent. The adjustable spectrum on the light fixture makes it so nice. The controller is a must have for this set up. The light is hanging 2 inches from the top of the tent and no need to have to raise it up or down. Two plants are flowering and are touching the light with no burning on any of the leaves at R80 % and W80%.

Starting anew 🤗👍🏻

My order is awesome,very pleased with quality, I did leave a message with Steve though-one of the lights did not have the hooks to hang the light with,only the electrical cord was in the plastic bag 🤷 but I made my own hooks 👍🏻👍🏻👍🏻

Great lights

The light arrived on time and my plant seems to be doing well with it so far! My only complaint is that they are cheaper now then what I paid...

Great product.


The unit arrived as promised
The instructions need to be a bit more clear on how to get from program 1-2-3-4-etc

Not working so well

After 2 weeks Plants under the SolarXtreme® 250 have barely moved. I have not had good luck with full spectrum lights. By contrast my Solar System 550 has worked very well. Need blue spectrum for veg and red spectrum for flower.

How close do you have the SX-250 to your plants? It does have both red and blue spectrum.

Side by side review

2 identical setups running spiderfarmer se5000. One with uvb 310 light and one without. Ran clones in the two seperate tents. Had light only 18inches from canopy and i ran last 3 weeks of flower at 2 hours a day mid light cycle. Both tents were in the same room, running at the same temp.

Tent with UVB had purpling edges and i would say had a stonger scent than the tent without.

Overall would buy again.

So far so good. I’m very pleased with the overall results and I’m impressed with the quality of the light

Spectra max 1000

Great coverage built nicely. Right now I’m doing a side by side with this lamp and two 550’s side by side. Only complaint with this is I wish they would do a limited run of a 3 channel utilizing blue diodes. Other than that it’s a very sleek and powerful lamp. Just needs blues 😉

Let there be light

Perfect fit for my tent
Used in conjunction with a simple timer device
Very cool

Nice footprint

I got my biggest plant under this, a Black Rock Lava Cake. She's going on week 7 of flower. I can fairly say at this point it's doing as good as my other lights. The customer service so far is a way better experience than Optic. And when I need a new light California Lightworks it will be.

Best light

This light has exceeded my expectations. It is a great light my only complaint is the controller is not sensitive enough I can barely press the buttons.

The best lights out there

I have Been using California lightworks for years now. I have the solorxtreme models as well. Both are built to the highest standards. I can honestly say I haven't had any issues thus far with Any of them. I definitely recommend the controller with it.you can set on off time, seasons, light intensity and spectrum control for flower as well as vegg. The instructions were very clear and easy and I set it up within 30 minutes. Just a awesome light manufacturer!!!!
