Super Nice

Light and controller are excellent. Both work flawlessly and I am super stoked thus far.

Great light!

This light performs better than expected.



SolarSystem® 1100 UVB

Exceed expectations

Long time grower… I have had many gardens over the years. I have never had a garden as healthy and a crop as heavy and dense as my crop now. The weight and the ripeness of the buds are something never achieved. I will definitely buy more and highly recommend!

Solar System UVB

This light arrived really quickly!First thing I noticed was the build quality,which I think is like the rest of their lights,exceptional!It's quite light,which brings to mind a couple previous reviews.It was pointed out in both reviews that the hanging clips seem inadequate. Imo they work great.When you attach the clips to the light,you'll likely agree, they aint letting go!!
Haven't had a chance to use it yet,when I do, I expect that there will be zero issues.Great company!!

So far so good

Got the 550 for our 7x7 Sturdi-Built Trillium Greenhouse on the recommendation of the folks at Sturdi-Built. I needed to move the centrer cross beam (very easy to do) and add a second one so the light is now suspended in the center of the greenhouse without being too close to any wood (which could block light and get damaged by heat over time). This light throws off a lot of light and we are putting the seedlings in this week. Wish us luck! Impressed by the build quality of the light thus far.

To be honest I haven't even opened the box yet because I trust in your quality products,and just know it will perform beyond my wildist dreams.

Great addition

Purchased the solar systems uvb

Used for one hour daily, at a 28inch hang
during last two weeks in a 2 x 4 setup.
There does appear to be a decent improvement in quality and quantity. Judging from same clone different grows with the new light addition. Very pleased. The light itself is built well, protect those eyes!

Good little light.

Nice bright light, needs an on off switch. I love the fan exhaust flow that points out with the cord, I can direct it out of my tents air flow holes. Perfect seedling (2x2) tent light

Solar Extreme 250 @ 500

As Covid hit everyone had to adjust. Brought all my babies inside and started indoor horticulture. Your lamps have been a constant source of light that I have never had a single problem from.(one less thing to have to deal with) these lamps
over the years I have used them. Looking now to upgrade and knowing your product reliability I will examine your new line of lamps. Thanx CLW

SolarSystem® 275

Great Lights!

I have 3 now, an 1100 and two 275's. Very bright! Plants seem to love them! Ordered the 275's on their Black Friday sale, I think they might have oversold, took a week to ship. Other than that inconvenience, I'd still give them 5 stars.

SolarXtreme® 250

Absolutely love it


Have used all different makes of LED, The Spectramax 1000 is everything you could ever ask for, and probably the most powerful light you can get for its price. Curious to see if there’s ever UVB integration for this setup. Couldn’t be happier. Quality is A++ if you’re debating on making this purchase. Go for it. You will absolutely not be disappointed with this product.

If I could give this light 10 stars I would. My wife is a succulent fanatic, so I bought the SolarXtreme 500 for my wife. The light after running almost 12 hours and passing my hand over both fans is running cool, placing my hand on the light fixture (not the glass) was also cool to the touch. The light is 18” away from the plants and working so well, plants are so healthy and strong in just weeks that she wanted another grow light. Long story short I bought a second SolarXtreme 500 light, it's working just as perfect as the first one. The light, feels and preforms like a high quality commercial light fixture.

Thank you California Lightworks

To soon to know

I haven't had a full run with these lights yet but they want a review. Lol. So... they are bright. Can't speak for results or performance but they appear to be well built and are very powerful and bright. Looking forward to the results after previously using the solar system 550 before.

So far so good

So far so good plants are responding very well. Great light uniformity. But only time will tell I will give a better review after the first harvest but so far so good been in California light works fan around 2013

I guess we will see

These things look and feel incredibly cheap. I can’t believe the price you charge for those materials. My plants are about to go into flower so hopefully I will be proved wrong once I start using them but I’m not holding my breath. I have 3 other CLW lights and love them.

All Good

This light is really doing the damn thing
