Additionally, the company is conscious of reporting the carbon emissions they reduce in their operations.

SolarSystem 275 LED Grow Light Product Information

The SolarSystem 275 is one of the lightest models by California Lightworks that also offers higher yields. This model replaces a 400-watt HPS with 40% less energy and draws a maximum of 200 watts, saving energy and cost. Although a small-sized grow light, consumers have reported it leaves a big footprint and is very bright. With the manual switch on the side of the product, you can also smoothly transition light spectrums from Veg to Bloom by placing it on a timer. 

Before shipping the product, all the fixtures will be tested with a burn-in period. The product package will come with the grow light, a 6-feet power cord, and a communications cable. This model is easy to install, never needs bulbs, and features a user-replaceable fan with a lifespan of 50,000 hours. Your SolarSystem 275 is also durable and resistant to high humidity conditions, including withstanding direct dripping.

Accessing the unlimited potential of programmable spectrum control will require additional purchase. However, this added investment is worth it, especially when considering the easy maintenance of the SolarSystem 275 that already lowers lifetime operating costs.

  • Fully programmable spectrum control compatibility

  • Versatile for commercial or personal size grows
  • Resistant to high humidity

  • 5-year warranty and money-back guarantee
  • Great 24 hours customer service

  • No ultraviolet-B (UVB) light mode
  • SolarSystem Controller is sold separately

Warranty Information

The SolarSystem series is protected for 5 years from the date of purchase for defects in material and workmanship as well as has a 90-day money-back guarantee. Since their products are built in the USA, they also have local customer service representatives to assist you with any problems or concerns.

Product Versatility

The integration capabilities and potential compatibility for small or large-scale operations make the SolarSystem 275 a rather versatile product. You can use each grow light individually or chain them together. It meets both the UL and CE certification standards for U.S. and European markets. Meaning, this light can grow with you as you increase your operation size from a single light in a tent to several hundred in large commercial operations.

If you choose to purchase the SolarSystem Controller, you can also access the multiple benefits of programming your spectrum control. The potential is limitless regardless of your growing operation size since the controller can be set up to program an unlimited number of lights in your grow space. This makes it one of the most versatile control systems available.

However, one downside to this model is the 2-channel capabilities that don’t include white light programming. The white channel will not affect the fixture when connecting the controller to your SolarSystem 275, and view mode will shut the light off. 

To access the full potential of your SolarSystem 275 grow light, you’ll want to purchase the SolarSystem Controller. The controller has a digital touch screen with a 24-hour clock that lets you:

  • Set minute by minute programming
  • Save multiple programs and routines 
  • Align with a day, week, month, or season calender 
  • Program an unlimited number of lights 
  • Use a digital timer 
  • Customize grow schedules for each strain 

Since the SolarSystem 275 only offers blue and red light spectrums, you may also want to integrate other lighting sensors or equipment, such as a UVB light add-on. Additionally, this product doesn’t come with ratchet hangers, so you’ll need to purchase hangers separately for installation
