SolarSystem® Controller

  • The SolarSystem controller works only with the California LightWorks SolarSystem 1100, 550, and 275. It can control an unlimited number of lights from a single controller. It allows automated programming for spectrum control, 24-hour timer, and day/week/month calendar. Now it is possible to program an entire grow cycle automatically – varying the spectrum, the length of the day, transitions from veg to bloom, final finishing modes, sunrise/sunset – all in a low cost easy to program digital controller.

    The SolarSystem Controller features programmable 0% to 99% spectrum control over three spectrum ranges – Blue, White and Red. You can use the controller in manual mode only to adjust the light spectrum or use the digital clock and calendar to run custom light recipes over a day, week, month or entire season. Programs can be saved for specific crops or strains. You can also use the view mode to work in natural white light and then switch back to high power reds and blues for accelerated growth.

    Take control of your grow operation!

lightworks controller

Just bought a second controller. Works great. I know of no other system that gives this much control of light intensity and wavelength mix.


I have been very pleased with the customer service that your company displays.


Recently purchased my second solar system 550 because I liked the first one so much. The new one has a design change that has much more white light. Both lights are great. Plants stay compact with no stretching. I highly recommend these lights. Im wanting to try the greenhouse pro 340


I have been using this light to get a jump start on my spring and let me tell you this light is amazing. I believe these lights exceed high pressure sodium, metal halide, and fluorescent lights in performance by double. I have had no issues with burning. And I really have not noticed any variance in my power bill. I will have full hanging baskets to sell by Spring and seriously considering buying another one next season

Best money can buy.

Best light money can buy. Best for quality . Controller changes the game . Automatic settings make it super simple .

Lighting arrived!

Dear California Lightworks, my new SolarSystem lighting fixture arrived on time and in good condition. It is not yet installed, however, as I am waiting for my son to have time to do that for me. I will let you know how it is working for me, once installed. Thank you, Melinda Cagle

Personally i think this should come with the lights.

While I have only used my light in veg stage, it only altered the color slightly. The nicest feature is being able to turn it to white light to work under the fixture. Maybe this is more useful for a commercial setting, but my one lamp setup in a 4X4 tent, $1000 lights, and accessories, this may be overkill?


This controller it’s badass , hands down, i can set my spectrum in so many different ways.

Solas system controller

Great unit. Has one flaw (that I see), you must leave the display on. Next version should be allowed to go dark after programming.

awesome product.

Best thing since sliced bread.Buy it you won't regret it.Very user friendly.
