SolarSystem UVB KIT

The UVB Kit consists of two SolarSystems UVB plus brackets.

The SolarSystem UVB of California Lightworks uses 25 watts per module and features the latest generation UVB T5 fluorescent bulb. The system is perfect for a single light in a tent or several hundred lights in a large commercial operation.

Overexposure to UVB light can be dangerous for plants, but small amounts of UVB light can have beneficial effects. UVB light enhances plant growth, improves essential oils and aromas as well as chemical profiles. Use caution not to expose eyes or skin to UVB light!

The SolarSystem UVB light can be combined with all of our LED modules to provide you with the most potent end-product. For the best possible quality, chain the two UVB's together with the SolarSystem 550 or Solarsystem 1100 in the last two to three weeks of the flowering phase for about 3-4 hours per day and connect them to a timer, it is recommended to use the UVB during the middle of the day.

UVB Module - Spectrum

UVB light is 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. Also be very careful not to expose your skin to UVB light.


Plants sense UV light which damages the DNA, therefore plants start to repair the DNA by creating enzymes. The plant creates an extra layer to protect itself which can be compared to the use of sunscreen.

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 the chemical profile of certain plants.

Please be aware that the UVB 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.
