SolisTek 600W SE 4K is a single-ended metal halide grow lamp built for high-frequency digital ballasts. The “4K” designation denotes an approximately 4000 K white spectrum that provides a balanced, blue‑rich output suitable for vegetative growth and transitional bloom. It features a standard E39 mogul base, low‑iron glass for improved UV/visible transmission, and a pulse‑start arc for faster ignition and stable PAR maintenance. When paired with a proper 600 W SE reflector/fixture, practical canopy coverage is about 4 × 4 ft. Typical rated service life is up to 10,000 hours. This lamp sits within Solis Tek’s high‑frequency MH family offered in multiple wattages and Kelvin options, and operates reliably with Solis Tek or other quality digital ballasts specified for MH lamps.
