Please note that the SolarSystem 275 has 2-channel dimming, as opposed to 3 on the 550 and 1100 models. If you connect the SolarSystem Controller to this unit, the white channel will have no effect on this fixture. As a result, view mode will simply shut this light off. Please contact us if you're not sure if this fixture is right for you.The SolarSystem 275 is suited for commercial, greenhouse, and personal growers. Able to cover a 3 x 3 foot bloom area and 5 x 5 foot vegetative area, it draws a maximum of 200 watts, saving energy and cost. This LED grow light system provides all the benefits of programmable spectrum control, meaning an unlimited potential for all types of growing operations.Using all parts of the light spectrum focuses energy into wavelengths plants need to thrive.

This commercial greenhouse lighting solution promotes all key biochemical and biophysical processes and helps drive photosynthesis, a natural process in which plants draw energy from sunlight to grow. Its full-spectrum grow lights can be dynamically controlled to adapt to each individual operation and phase of the plant cycle.The SolarSystem 275 is not like ordinary greenhouse grow lamps. Heat output is minimal, and each of our horticulture LED lights can be used individually or chained together. It also requires little maintenance, so lifetime operating costs and convenience plus easy installation make your investment worthwhile.

275 Up and running

Set up a 275 with controller in a 3x3 tent with developed seedlings. Have program set up using recommendations from CLW manual since I'm new to this technology. Controller very easy to set up. Let's see what happens!

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.

SolarSystem 275 (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.

Great lights

These 275 are giving me big fat smelly intense buds, and I’m so happy with energy consumption and quality of end result. I have 250 series for veg and 275 on controller for flower . Total lights 9. Really working well.

Sweet system !

In a small 2 X 3 space with HPS, I was having big trouble with heat and running up the power bill trying to keep it cool. This little beauty cured those problems! My room is running so cool now, I can't believe the difference. It's only been a few weeks, but the plants look absolutely perfect. Just as happy as could be and growing fast! Glad I got the controller and can dim specific light spectrums and change them through veg and bloom. It's awesome, I want another one already! lol And Adam was great to work with!
Thanks CLW

Absolute best!

As a grower that grew up in an age of ballast and bulbs my solar 275 is the best. I have a small closet starting 10 plants to move out to the greenhouse. Power use is minimal, heat is barely notable but more importantly the spectrum of light has produced better growth than the real sun without worry of frost, and nosey visitors. I highly recommend this lighting system to any grower for seedlings or to grow to maturity. You will not be disappointed!

I've had this light for 5 weeks now, I already had a SS 550.
It's doing just what I'd hoped. CLW lights are so freaking strong you need to take light and plant placement seriously. I have an irregular shape growing area and adding this light really helped balance things out.
I've come to see that you just gotta get that photon app ( light meter) especially with the clw lights, it's spells out your daily light index, from there you can get the lights in the right place at the right height. When the clw people tell you to keep there lights a bit higher that most others, they ain't fooling around. These lights are rad, solid, better programing than anything else I've seen on the market and I got some stuff flowering at the moment and I've never seen such rigerus trycomb covered tight buds this early in the flower stage before. I'm stoked about the lights and the people you deal with at CLW are always super happy to help . No regrets
