King X4 1200W is a COB‑based LED grow lamp from King LED lights’ former X‑series. Despite the 1200W model name, user measurements report actual draw around 200–215 W and suggest it for small spaces. The fixture uses four COB modules with a dimmable driver and a broad spectrum including blue (~450 nm), red (~660 nm) and far‑red/IR (~730 nm), with some UV near 410 nm. Typical effective coverage is about 2×2 ft for a compact canopy; larger footprints generally require multiple units. Physical dimensions are roughly 31×21×6 cm (12.2×8.26×2.36 in).
