SolarSystem 275 - Spec Sheet

The SolarSystem features the latest generation high efficiency LEDs as well as the most versatile control system on the market. This system is perfect for a single light in a tent or several hundred lights in a large commercial operation.

The SolarSystem controller works with one or 1,000 lights and controls our entire family of SolarSystem LEDs. The system grows with you as you increase your grow operation.



The SolarSystem LED grow lights won the Spannabis 2017 ‘Best Grow Product’ award beating off some top quality competition from some well established grow light companies and the completely renewed SolarSystem Series was released in 2018. The professional grade SolarSystem LED grow lights are built in the USA for the legal USA grow market and are available in Europe through Crazy LEDs. With unsurpassed build quality, highest quality Osram LEDs and an intense light spectrum designed exclusively for cannabis growing, the SolarSystem LED grow lights will allow you to grow better cannabis than ever before.

Only a select few tell you the important metrics of a horticulture lighting system and PPFD  is definitely one of them! To some extend you could say: the higher the PPFD measurements, the higher the rate of photosynthesis and final yield will be. We recommend an average PPFD between:

100 and 300 μmol/m2/s for Seeds (for optimal conditions: additional CO2, ~400 ppm)
75 and 150 μmol/m2/s for Vegetative Cuttings (for optimal conditions: additional CO2, ~400-800 ppm)
300 and 600 μmol/m2/s for the Vegetative phase, including Mother plants (for optimal results: additional CO2, ~400-800 ppm)
600 and 1000 μmol/m2/s for optimal results during the Flowering/Reproductive phase, without additional CO2 (for amazing results: additional CO2, ~800-1400 ppm)
1000 and 1500 μmol/m2/s for phenomenal results during the Flowering/Reproductive phase WITH additional CO2, ~1400 ppm. Most strains can not thrive or even handle this photon flux density without supplemental CO2


The SolarSystem 275 VEG is a specialist LED grow light designed for rapid vegetive plant growth. The SolarSystem 275 VEG has the same design as the full cycle SolarSystem 275 but with with much more intense blue LED light. The SolarSystem 275 VEG features the latest generation high efficiency Osram LEDs as well as the most versatile control system on the market. If required, the SolarSystem 275 VEG can be daisy chained together with hundreds of other SolarSystem lights and all controlled from the optional hand controller. The light will cover a 150 x 150cm (59'' x 59'') area during vegetive growth and replaces a 400W HID during vegetive growth.

Please Pay Attention! When used in combination with the Controller:

Only the red and blue diodes are controllable (two controllable drivers), so there is no 'white light' viewing mode. The white diodes are connected to the drivers of the blue and red diodes.

(To use all features, you will need the Controller. The Controller is sold seperately.)
SS Controller
200W power draw

Approaches a 400W HPS but with less heat production and lower energy costs

The SolarSystem 275 VEG uses up to 200W on maximum power. The light spectrum has been designed for the fastest vegetive growth possible and uses primarily blue and white Osram LEDs to bathe your plants in an intense light that will allow the best possible start. The Spectrum is blue dominant with some red light which is essential for early plant development, the spectrum has been fine tuned over several years for optimal vegetive growth. The SolarSystem 275 VEG light suits the passionate home grower who is looking for the best possible LED grow light for vegetive plant growth.

Adjustable power from 0-100% (CONTROLLER needed!)
The SolarSystem 275 VEG is the only light you need for germination, seedlings and mature plants. There is no need for separate fluorescent lighting for seedlings and metal halide lights for vegetive growth.  The SolarSystem 275 VEG performs all the necessary functions in your grow room. You can save money on energy costs by steadily increasing LED power levels as your plants grow, starting with low energy and increasing to 100% power in full bloom.

Adjustable spectrum (CONTROLLER needed!)
Independent control of the red and blue LEDs allow you to find the perfect growing spectrum for your favourite varieties. If your Sativa is stretching too much you can reduce the red spectrum and increase the blue to reduce internodal distance. If your indica is to short you can reduce blue light and increase red spectrum to increase internode distance and build a bigger plant structure. The SolarSystem 275 VEG brings professional levels of controllability into the hands of the home grower.

Please note: The SolarSystem 275 VEG cannot be put into view mode with the SolarSystem Controller, like the SolarSystem 550 and 1100. It also does not have a separate white channel like the aforementioned units. Please contact us ( before purchasing this unit to find out if the SolarSystem 275 VEG is the right light for you.

Proven Design
Several years of grow light manufacture has resulted in a highly reliable and fully proven LED grow light with superior quality components and a design you can trust.  California Lightworks have supplied USA commercial growers with LED grow lights for several years - the technology and designs are tried and tested.

Sunrise/sunset option (CONTROLLER needed!)
Some cultivators believe that plants can’t adjust instantly to full light intensity, it causes stress and the plants may need up to half an hour to wake from sleep and start to photosynthesise at full speed.  The SolarSystem 275 VEG allows you the option to steadily increase/decrease light power at the start/end of the day to replicate the more natural light transitions of the sun.

5 Year Limited Warranty

Benefits of the SolarSystem LED grow lights

Using the optional hand controller you can adjust the spectrum and the intensity of the LED grow lights. Without the optional hand controller, all LED power levels are set to 100% and can’t be adjusted. On the SolarSystem 1100 and SolarSystem 550 the red, blue and white LEDs are on separate electrical circuits. This allows them to be separately controlled. On the SolarSystem 275 VEG the red LEDs are on one circuit, and the blue and white LEDs are controlled on the same circuit (not separate circuits). This means that blue and white LEDs can’t be controlled independently on the SolarSystem 275, its a small restriction, but one which future buyers should be aware of. With the hand controller the LEDs can be programmed to switch on and off automatically, with a sunrise/sunset mode to gradually turn the lights on/off. Additionally, the fully programmable hand controller allows you to control up to 1000 lights at a time by connecting the SolarSystem lights in a ‘daisy chain’ arrangement using standard RJ11 telecom cables (supplied). The SolarSystem LED grow lights were designed for maximum user convenience and were built to the highest possible standards using top-specification Osram LEDs.

Programmable controller
(not included. Buy/More info on this page)

Using the controller you can connect and control multiple SolarSystem LED grow lights which connect together with a standard RJ11 cable (supplied). The controller also allows you to adjust the spectrum from the SolarSystem 275 VEG. The SolarSystem 275 VEG contains red, white and mainly blue Osram diodes. The blue and red diodes are controlled on separate circuits. This allows you to adjust the light spectrum according to the specific needs of your plants during veg. The controller also allows advanced programmable control over your LED grow light and allows sunrise/sunset modes for better daily growth and even allows your whole grow to be programmed months in advance for seedlings, veg and bloom growth. The in-built digital timer eliminates the need for external timers or contacts and allows customisable grow schedules for each strain.

Using multiple SolarSystem 275 VEG lights together.

We understand that many home growers like to link several grow lights together, and with the SolarSystem 275 VEG that is easy to do. Each light has its own power cable. If you are controlling all your SolarSystem 275 VEG lights from a single controller then the controller needs to be plugged into one of the SolarSystem 275 VEG lights. The remaining SolarSystem 275 VEG lights are all daisy chained to the first SolarSystem 275 VEG with standard ‘telephone-style’ connection cables. Using this system you can control a grow room full of SolarSystem 275 VEG lights.
