Overview

Meet the KingPLUS KingLED KP4000, a high‑efficiency 400W full‑spectrum LED grow light designed for indoor gardening. With 2304 LEDs across red, blue, white, and yellow, it delivers a bright, even glow that supports seed starting, vegetative growth, and flowering phases without cluttering your space. The light’s output is intense enough to reach deep into the canopy while remaining energy efficient.

Designed for compact spaces, the KP4000 fits 5x5 ft or 4x4 ft tents, hydroponic systems, greenhouses, basement shelves, or living room setups. It offers three growth modes for different stages: VEG for seedlings and leafy greens, BLOOM for flowering crops, and VEG+BLOOM for a full life cycle. Height adjustment is simple with the included ratchet hangers, letting you fine‑tune intensity by raising or lowering the fixture rather than juggling extra controls.
