King Plus 1500W
Grow Lights260W
The King Plus 1500W sits in the upper half of KingLED's double-chip line: 150 pieces of 10 W Epistar diodes, a stated draw of about 260 W, and the same spectrum as the rest of the series — 410 nm, 430–440 nm, 450–475 nm, 620–630 nm, 650–670 nm, white and IR at 730 nm.
The panel is 400 × 213 × 60 mm, or 15.75 × 8.39 × 2.37 inches, and covers about 4 × 5.6 ft. It runs on 85–265 V at 50–60 Hz, cools with fans over a 3.0 mm board, and is rated past 50,000 hours.
260 W over a 4 × 5.6 ft footprint is thin if you push it as a sole flowering light; treat the coverage figure as the outer edge, not the sweet spot.
