King X4 Dimmable 1200W is a compact COB-LED grow light from King LED lights for full-cycle cultivation. Independent sources describe a full-spectrum output covering approximately 410–730 nm with infrared at 730 nm, operating at 50–60 Hz. The X4 uses a chip‑on‑board module rather than dispersed SMD diodes and is dimmable to match plant stage and canopy distance. Reported physical size is about 12.2 x 8.26 x 2.36 inches. Real-world power draw is cited around 215 W, with a recommended coverage near 4.2 x 6 ft for indoor gardens and tents.
