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.

The SolarSystem 275 has a maximum power draw of 200W and is a great choice for growers with smaller grow tents, such as 60 x 60cm (23,62'' x 23,62'') or 80 x 80cm (31,5'' x 31,5'') grow environments. The performance approaches, but doesn’t exceed that of a 400W HPS. Like the rest of the SolarSystem range, it uses blue, deep blue, red, deep red and white LEDs. This allows for good vegetive growth as well as good results in bloom. The spectral wavelengths have been chosen purely for growing cannabis and have been fine tuned in the USA over several years.

(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

Adjustable power from 0-100% (CONTROLLER needed!)
The SS275 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 SS275 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 SS275 brings professional levels of controllability into the hands of the home grower.

Please note: The SolarSystem 275 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 (sales@ledbypassion.com) before purchasing this unit to find out if the SolarSystem 275 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 SS275 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 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. The SolarSystem 275 contains red, blue and white Osram diodes. The blue, white 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 SS275 lights together.

We understand that many home growers like to link several grow lights together, and with the SS275 that is easy to do. Each light has its own power cable. If you are controlling all your SS275 lights from a single controller then the controller needs to be plugged into one of the SS275 lights. The remaining SS275 lights are all daisy chained to the first SS275 with standard ‘telephone-style’ connection cables. Using this system you can control a grow room full of SS275 lights.
