(HDL) High Output Downlight

The HDL High Output Downlight family is engineered to deliver precise, high-intensity illumination, especially in spaces with high ceilings and demanding visual requirements. Powerful lumen packages up to 10,000lm enable mounting heights up to 24 feet.

Wet-location rated below the ceiling, the HDL confidently extends from interior spaces to building entrances and overhangs, ensuring consistent illumination for safe and welcoming entryways.

Common applications include automotive dealerships, transportation hubs, and transit halls. Retail, financial institutions, libraries and art galleries with multi-story stacks use this product to provide the focused, high-fidelity illumination without harmful UV exposure.

With powerful outputs, fewer compromises, and confidence at every height, the HDL is designed to help you reach higher.
