SS550  Controllable Spectrum example

SolarSystem 550 - Spec Sheet


The SolarSystem 550 uses 400W of power on maximum power, it suits people growing in 100 x 100cm (39,4'' x 39,4'') or 120 x 120cm (47,25'' x 47,25'') grow environments with results approaching that of a 600W HPS light. The SolarSystem 550 has similar PPF light output to a 600W HPS with reduced heat which allows quality improvements over HPS grown crops.


(To use all features, you will need the Controller. The Controller is sold seperately.)
SS Controller
● 400W power draw
Approaches a 600W HPS but with less heat production and lower running/energy costs

● Adjustable power from 0-100% (CONTROLLER needed!)
The SS550 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 SS550 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, white 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.  And you can turn off both blue and red light to view your plants in the special ‘White Light’ plant inspection mode.  The SS550 brings professional levels of controllability into the hands of the home grower.

● 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 SS550 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.

● 3 Year Manufacturer Warranty / 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 allow 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.

Spannabis Award for 'Best Grow Product 2017’

The SolarSystem grow lights won the prestigious Spannabis 2017 Award for ‘Best Grow Product’. Thats a significant breakthrough for LED grow light technology and recognises the price, performance and build quality for these professional grade products. What made the Spannabis award extra special was the quality of the technology and companies that were also competing for the same award.

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 550. The SolarSystem 550 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 SS550 lights together.

We understand that many home growers like to link several grow lights together, and with the SS550 that is easy to do. Each light has its own power cable. If you are controlling all your SS550 lights from a single controller then the controller needs to be plugged into one of the SS550 lights. The remaining SS550 lights are all daisy chained to the first SS550 with standard ‘telephone-style’ connection cables. Using this system you can control a grow room full of SS550 lights.
