Great lights

So far the light works great! My plants are growing fast. It's exciting to see what they look like every morning when I water them.

Pepper Plant Lights

Works great and my plants are very happy. Setup on a timer and let it work. Funny thing is our cats love sunning in the light.

Missing 1 bracket, can't set time on controller

Light is great. Unfortunately they left out 1 bracket for the UVB lights.
Also ordered the controller and it appears that I can't set the time.
Other functions seem OK.

Powerful light

I own three CLW lights. I’ve ran this light for two cycles now. This light can produce excellent results. However, it runs wayyyyy too hot for a lot of tents. My basement is 66-70 degrees. I had it in a 5x5 and had to upgrade a lot of equipment to keep the tent cool. Now it’s in a 4x8 with another cooler light. Had to buy a portable AC to still use it. Two high velocity exhausts, 2 large duct intakes, 4 fans, and in a basement wasn’t enough. I personally don’t think this light is meant for tent growers.

Spectra max 1000

So far so good. Very nice craftsmanship. If your thinking about buying it you won’t be disappointed.

Wow Magenta Color Spectrum

The 550 Light is competitively priced and arrived in pristine condition. I'm looking forward to putting it into service next April when my Heirloom Roses arrive.

Thriving and Plush as you could imagine

In 9 days my tent has gotten so full it’s unreal . I cannot believe my eyes , I just can’t . I’ve never seen plants react in such a way … DO NOT HESITATE TO GRAB THESE LIGHTS ! I’m using one Solar extreme in a 4x4 and YEAHHHHHHHH

CALIFORNIA LIGHT WORKS ( Thank you so much )

Good quality- Fair price

Really fine quality. In this day and age of rushing for the lowest price possible companies sacrifice quality.
Nice to know and use these lights.

Easy set up

I got my SolarSystem 550 and Controller, just at the start of flowering stage, on my first plant. An autoflower, Norther Lite. I watched some Youtube videos California Lightworks put out on how to program and use the controller. I was running a flowering program and setting up a calendar to run a finishing program in no time at all. The plant took off right away. Looking very good!!! Lots of nice white hairy buds!! Great product!!

Timer is amazing

Makes life simple . Worth the cost. Have in flower so havent got to play with setting much.

Amazing light

Absolutely amazing light I'm getting some of the bushiest plants I've grown very similar to a thousand watt HPS but even better in my opinion I'm currently not using the controller with it but even without it I'm producing amazing results. Customer service is also amazing I've called a few times and emailed back and forth a few times and everybody is super helpful and courteous. My only issue and the only reason why I gave four stars. per performance five stars all day, but price to performance not so much, yes they're great lights but in the present market, we have amazingly efficient grow lights just as good as these for considerably less sometimes up to 50% less. California light works are currently up to date on technology and performance with their lights I'd like to see them also get up to date with pricing as well.

Solar extreme 500

Love the light, very well made I have only grown one plant since having it but I noticed a big difference between the old light and this new one. Great product.

solar System controller

This is a great controller. So far just in veg but looking forward to the future program. Love the ability to adjust spectrum. Took seedling plant out of a cabinet, put in new room and the plant is taking off. 1 more week heading into bloom . Next grow looking for full program.

California light works UVB

This light is amazing. It does exactly what they said it would and more. Bring on the terpenes...

Worked good

Made a difference in the amount of trichomes . We’ll see if it makes a difference in potency. I would buy again and probably will.

California light works is the best!

I have owned the solar storm 440 for about 10 years . It has served me well. I had to downsize my grow from a 4×4 to a 3×2 . I will say my old modle grew some beautiful thick colas . Harvest after harvest the 440 never let me down . Worth the money for sure! Thanks California lightworks for over a decade of wonderful harvests.

SpectraMax Controller (Absolutely recommend)

I’m an experienced grower. Over the years, for LED lighting, I’ve tried three other high end companies, for these other cases quality was good however results were okay/good. For the past recent years I’ve been using three different California Lightworks SOLARXTREME models. From my experience, the plant response to the SOLARXTREME models is incomparable. Plants sing and glow when lights are on. It’s really something special. I’ve always been super happy with the SOLARXTREME models however I’ve been a little bummed, for experimental purposes, this series is without built-in control for timing, spectrum adjustment and dimming. I recently purchased two SolarSystem models with the external controller. Wow! It’s exceeded expectations. Plants continue to glow and sing plus I have all the controls I need. No exaggeration here. I absolutely recommend the SolarSytem series and the controller and the SOLARXTREME series. One of the SOLARXTREME models I purchased had an electrically broken fan on its arrival. Customer service / tech support over the phone was perfect for handling the replacement. Also made in the USA. I’ll never buy from another company. Quality is top notch. The controller is well designed as well.
