Know before you buy
The HLG Blackbird is specifically designed for a 4' x 4' flowering footprint when hung at a height of 20 to 24 inches. For vegetative growth, it can cover a larger 6' x 6' area if the light is raised to 30 inches.
No, the Blackbird features a passive-cooled design, meaning it relies on its physical structure to dissipate heat rather than noisy internal fans. This ensures silent operation and reduces the number of moving parts that could potentially fail.
Yes, the unit includes a dimmable power supply that allows you to adjust the output anywhere from 100 to 600 watts. This flexibility lets you lower the intensity for seedlings or clones and increase it as your plants move into the flowering stage.
The six-board configuration is engineered to provide exceptionally even light distribution across the entire canopy. By spreading the light source across multiple boards rather than a single point, it improves penetration and minimizes hot spots.
The lamp uses a full-spectrum blend of white and deep red LEDs. This combination is optimized to support your plants through both the vegetative and flowering cycles without needing to swap out equipment.
The unit features a wide voltage range of 120-277 VAC, making it compatible with standard residential outlets as well as higher voltage commercial setups. Always ensure your specific outlet configuration matches the plug type provided with your unit.
