SolarXtreme 500 UVB combines California LightWorks’ 400 W SolarXtreme 500 LED with the SolarSystem UVB kit for supplemental ultraviolet exposure. The LED uses a COB, driverless AC design and delivers full-spectrum output for all stages. Coverage is 4 x 4 ft in bloom (5 x 5 ft veg). The kit mounts two UVB T5 fixtures alongside the LED. The SX 500 fixture measures 18 x 8.5 x 4 in and weighs about 5 kg, with active cooling and heat output around 1,280 BTU. Typical hanging heights are 18 in for flower and 24 in for veg. This bundle targets growers seeking a simple, plug‑and‑play setup that adds controllable UVB during late flower without changing the main spectrum.
