SolarSystem 550 UVB

The SolarSystem 550 UVB of California Lightworks is a professional and powerful LED grow light which is designed for commercial indoor horticulture. The SolarSystem combined with the UVB LED light can provide you with an even higher yield. For the best possible quality, add the UVB's in the last two to three weeks of the flowering phase and connect them to a timer to elevate the chemical profile of certain plants.

The power and spectrum of the SolarSystem 550 can be adjusted if you connect the SolarSystem controller. The controller allows you to manually or automatically control the light’s spectrum and power, it eliminates the need for an external timer.

With this purchase you'll receive one SolarSystem 550 with two SolarSystem UVB's.

You can use the system as a single unit in a tent or with multiple units chained together in a larger application. The SolarSystem 550 uses 400watt on full power and can easily be compared to a 600 watt HPS light. The waterproof system is developed and produced in California and features OSRAM LED diodes, which are the most powerful LEDs available. The SolarSystem UVB only uses 25 Watt per module.

For the best yield, add UVB's in the last two weeks of the flowering phase and use them for about 3-4 hours per day.

Spectrum UVB LED By Passion

LED light can be harmful for your eyes, therefore we recommend you to wear the Method Seven glasses to protect your eyes. Besides protection, the glasses filters the light to normal daylight colours which allows you to see the normal green colour of the plant.

- Control/program the entire growth cycle
- A single controller handles un unlimited number of lights
- Automated program for sunrise/sunset

- Digital timer eliminates
the need for other external timers

- Day, week or season program

- Smooth transition from veg to bloom


One of the benefits of the SolarSystem 550 is that the LED diodes (red, blue and white) are located on separate electronic circuits cq. drivers. This means all three channels (blue, red, white) can be controlled separately and set with the controller, in comparison with the SolarSystem 275 where only two channels (blue and red) can be controlled.

The advantage here is that you can set for example more blue light in the growth stage of the plant, when the plants need it the most. If for example your sativa is stretching too much you can reduce the red light and increase the blue to reduce internodal distance. On the other hand, if your indica is too short you can reduce the blue light and increase the red light to enlarge the internode distance and build a bigger plant structure. The controller also allows the LED's to automatically and gradually switch on and off at sunrise or sunset.

The light system is very light in weight (about 6kg) and has a very large coverage area, compared to other systems. The grow light is ideal for professional home growers who want to increase yields, quality and profitability. The benefit of using an UVB light is that this light enhances plant growth it improves essential oils and aromas as well as chemical profiles.

If you would like to use several SolarSystem's 500 at the same time, they are easy to connect to each other with a phone cable. You can connect the controller to the first SolarSystem and daisy-chain (link the others accordingly), the controller can handle up to 1000 lights.

Important information !

Please be aware that the UVB LED grow light can damage skin and eyes. Therefore it is very important you turn of the light before entering the grow room. Use this light only in dry locations, otherwise you risk an electrical shock. Do not use this light on a dimmer circuit and only use the SolarSystem T5 UVA bulb. Always use a Method Seven glasses to protect your eyes.

Overexposure could be harmful for the flora, however small amounts of near-UV light can have beneficial effects. This is an indication of near-UV light effect on metabolic processes. Studies show that 385 nm UV light promotes the accumulation of phenolic compounds, enhances antioxidant activity of plant extracts, but does not have any significant effect on growth processes. UVB has also been demonstrated to elevate chemical profile of certain plants.

Award winner

The SolarSystem LED grow lights won the Spannabis 2017 “Best Grow Product”, beating off some top quality competition. The SolarSystem series has been completely renewed in 2018, the efficiency improved greatly by this update. The LED system has been designed and produced in the USA, with the highest quality OSRAM diodes and a well balanced spectrum.
