Product Overview

The Ultra-Thin PB Series Quantum Board LED Grow Light (available in 100W, 200W, and 400W configurations) is designed for indoor plant cultivation, grow tents, plant racks, and greenhouse supplemental lighting. Featuring an optimized diode placement layout, it generates an even light distribution of up to 1625 umol/m²/s PPFD at 30 cm, promoting uniform plant growth and higher yield potential.

Constructed on an ultra-slim aluminum substrate, the fixture utilizes passive heat dissipation to maintain low diode temperatures without mechanical fans. Its full-spectrum output (3000K + 5000K + 660nm Red) targets critical photosynthetic absorption bands, while the IP65 waterproof coating ensures long-term reliability in humid grow rooms.
