Are you looking for maximum coverage, top-tier light uniformity, and professional-grade yields? The LED Grow Light PH-B8-D 640W is a heavy-duty, 10-bar grow light that delivers an incredible efficiency rating of 2.8 µmol/J (PPE) and supports a massive potential yield of up to 2.5 grams per watt. It is engineered to provide a perfectly uniform, hot-spot-free footprint across large 1.5 x 1.5 m grow tents and rooms.
At the core of this fixture is a massive array of 2,160 genuine Samsung 281B LEDs, ensuring industry-leading light intensity and highly stable performance.
Why choose the PH-B8-D 640W?
- 10-Bar Professional Layout: The multi-bar configuration distributes light exceptionally evenly across the entire 1.5 x 1.5 m area. This eliminates shadows and guarantees that edge plants develop just as robustly as those directly in the center.
- True Samsung 281B LED Spectrum: Equipped with 1296pcs (3500K), 576pcs (6500K), and 288pcs (660nm) deep red LEDs to create an optimized full spectrum that accelerates vegetative growth and maximizes flowering potential.
- 100% Silent Passive Cooling: Despite its solid 14 kg build and immense power, this fixture features no noisy fans. The aluminum chassis dissipates heat silently and efficiently, ensuring a long 50,000-hour lifespan.
- Advanced Daisy Chain Dimming: Features a multi-stage dimmer knob (OFF-20%-40%-60%-80%-100%). Easily link multiple lights together and synchronize their intensity across your entire grow room from a single master controller (0-10V control).
- New Clear Waterproof Glue Technology: The protective layer over the LED bars utilizes an advanced clear waterproof glue coating, keeping the electronics safe from high humidity and splashes without sacrificing light output.
- Certified Quality & Safety: Built with an integrated, UL-listed waterproof driver. Backed by a 3-year warranty, CE approved, and DLC & ETL listed for complete peace of mind.
