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!

works when it wants to

I bought my controller for my light about a year and a half ago and it worked great for one whole grow cycle then outta no were it would just stay on and the time would get froze up and I would have to reset it

Hi Jesse, I sent you an email to help you solve this issue. The firmware on your controller most likely needs to be updated which you can do yourself, or we can do that for you if you send your controller in.
Works great

I bought a controller about a year ago. It wasn't working right all the time but I contacted California Lightworks and they swapped it out for me with a controller with new firmware. This controller has been working great since then with no issues. Great customer service!


The option for sunrise and sunset is wonderful. The touchscreen is very hard to use. It just doesn’t work right. I hit the screen and it activates something next to it. Not sure if it’s just this one or all of them. To late to return. My plants are in the middle of growing. Other than that I like the light 550. I do love the idea of the controller. Just wished it was a bit better.

controller review

So far the controller I have received has worked great. I watched several youtube vids regarding programming entire grow cycle into controller before receiving it so it was a breeze to program. So far so good. No problems at all to speak of. Happy with my purchase of this controller and both 550 lights

I know it has potential...

This is my second controller and was a bit disappointed that the screen is not placed correctly, off center. And the touch screen is frustrating to work with. The screen is not responsive. So I have to push the "buttons" over and over again just to change the values, ie. If I want R99, I have to press the box for the value, then "+", it won't change the value and will click off the selection. Soo then I have to press the value button again and then press the "+" again, and hope the value will at least go up once before I have to press the value button again. Takes about 60 secs to go from 0-99 for each value. And not to mention any other selection I want to change, they all take longer than they should. I should be able to press once and get the next value...

So to say the least, it's a waste of time and patients. I know it has great potential but this particular device is faulty. My other one works great. Could be a good product but not this one. Kind of frustrating with the inconsistency of product.

All in all, I really do like the ability to alter the parameters of the light. Many plants react differently under different spectrums, so it's nice to experiment and fine tune what spectrum is best for each plant you are growing.
