Solis Tek 400W 10K is a high-frequency, pulse-start metal halide finishing lamp for horticulture. Rated at 400 watts with a 10,000 K color temperature, it uses low‑iron glass to increase UV transmission compared with standard envelopes. Within Solis Tek’s MH range, the 10K spectrum is intended for the final bloom window, typically swapped in for the last 7–14 days to promote ripening and finish. As a 400 W HID source, it is commonly used over roughly 1 m² canopies, fitting 100×100 to 120×120 cm tents depending on reflector and ventilation. Designed for use with compatible MH/digital ballasts, it emphasizes blue/UV content during the finishing phase.
