HLG 600W Blackbird
A high‑efficiency, dimmable LED Quantum Board fixture delivering around 1,567 µmol/s output at up to 600 W (≈2.79 µmol/J) with full-spectrum white + deep‑red diodes. Passive cooled, auto‑sensing, IP rated and ideal for a 4×4 flowering footprint.
Designed for home growers and smaller commercial spaces, the Blackbird employs six QB‑200 Quantum Boards loaded with Samsung LM301H + deep red (660 nm) LEDs. It runs dimmably from 100 to 600 W, supports 120–277 VAC auto-sensing input, and provides even canopy penetration thanks to diffused light output. Passive cooling eliminates fans and enhances reliability. Suitable for full-cycle vegetative and flowering growth, it covers roughly a 4’×4′ flowering tent when mounted 20–24″ above canopy, or up to 6’×6′ in veg. It includes a manual dimmer and optional GrowFlux controller compatibility. Warranty is 3 years.

Frequently Asked Questions
Better build quality, more even coverage with 6 quantum boards, Meanwell driver reliability, and established brand support.
Yes, external driver generates some heat but can be mounted remotely to reduce tent temperature.
100W minimum to 600W maximum, smooth dimming throughout range, no flickering or dead spots.
Excellent, 6 separate QB200 boards provide very even PAR distribution across 4×4 area, minimal hotspots.
Yes, low profile design works well with 6-7 foot ceilings, can be mounted closer to canopy than single-board designs.
