This is important because, although the natural light from the sun contains significant quantities of UVB, HID and LED lights do not normally cover the UVB spectrum (since LED lights focus through contracted diodes they only offer a slim spectrum). To overcome this problem and to produce lighting that more closely mimics the natural energy from the sun, California Light Works have included T8 fluorescent UVB bulbs within the structure of the SolarStorm 440. These UVB lights have a separate control so growers can regulate their usage, providing optimal UVB levels at the required stages of growth (typically during the final weeks before harvest in order to boost growth).
Designed for medium sized or home grow operations, the SolarStorm 440 grow light offers comparable output to the traditional 600w HPS or Metal Halide systems, but at a far cheaper running cost and minimal heat output. The result of much research and consultation with local indoor growing experts. 144 high flux bin OSRAM SSL emitters with a narrow radiation pattern to increase lighting efficiency. Covers 3 feet x 3 feet during the blooming stages and 6 feet x 6 feet in the vegging stages. T8 fluorescent UVB bulbs for lighting that more closely mimics the natural energy from the sun.
