SolarSystem® 550

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.

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!!

Only my 2nd grow, but really impressed and the controller makes a night and day difference

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.

I spec stage, studio, and architainment (yes that's really a word) lighting as my daytime job, I'm also a member of the Illuminating Engineering Society, so you might say I have a bit of background... This is my 2nd SolarSystem 550. I bought the first after some research and reviews. Osram LEDs, programmable spectrum control, American made, and 5 year warranty were deciding factors. Plants are looking awesome, starting to flower now. I'll be adding UVB soon.

I've been using California Lightworks products for years and I recently decided to swap out my (2) Solar Xtreme 250's and (1) Solar System 275 from my 2x4 6 foot tall tent and upgrade to (2) Solar System 550's.

This equipment is well worth the expense. In the first month of growing new plants I have seen a noticeable difference / improvement in the rate of growth.

I also added a humidifier to this tent at the same time therefore some of what I have seen can be attributed to the humidifier providing ideal humidity conditions.

I'm looking forward to these flowers when they're finished growing. The first of many flowers that will be grown under my pair of Solar System 550's!

I can’t believe the difference these lights have made!!Controller is a must have to get the best out of lights

SolarSystem® 550

This is the second one of these that i've purchased, i got a fluence spydr between them, but the fluence ballast are crap, soo i decided to stick to what has worked.

3 SS-550s, 4x8 tent (25amp circuit handles ALL)
Tent temp 78° - 82°, everything full on.

corner to corner light coverage, no shadow around object on floor. Seedling stage from sprout to seedling produced really healthy trueform plants. Kinda stupid to buy the lights without the controller. Makes all the difference.
