KP4000
Grow Lights400W
The KP4000 is the largest panel in KingLED's KP series: 2304 LEDs sold under a 4000 W name; the actual draw is 400 W.
The board splits into 896 white and 896 warm-white diodes with 256 blue at 460 nm and 256 red at 660 nm, the white channels running 3000–5000 K. Separate VEG and BLOOM switches bring up the blue-and-white set, the red-and-warm-white set, or everything at once.
KingLED states a 4 × 4 ft or 5 × 5 ft footprint, which puts the KP4000 in full-tent work rather than on a shelf. An aluminium heat sink and quiet fans hold it in the 50–60 °F band while it runs. The fixture takes 100–240 V at 50/60 Hz, measures 28.9 × 13 × 4.13 inches and weighs 10.58 lb; a power cord, a rope hanger and steel hooks come with it.
