HDLS-100W High Bay Light — Powerful, Efficient, Stadium-Grade Illumination

The HDLS 100W high bay is engineered for demanding indoor venues — sports courts, gymnasiums, warehouses, and industrial halls — delivering bright, uniform illumination with industry-leading efficiency and reliability. The PC ring lens and carefully tuned optics produce focused, glare-controlled light while preserving color fidelity and visual comfort for athletes, staff, and spectators.

We offer CCT, CRI, and optical distribution customization to match your venue’s performance and visual requirements. For project quotes, photometric files (IES), or controls integration support, click Inquire Now or contact our sales team.

Why Choose HDLS-100W

Exceptional luminous efficacy — up to 168 lm/W, giving a typical output of ≈16,800 lumens at 100W for bright, energy-efficient performance.
· Customizable light distribution — available beam angles 60°, 90°, and 120°, so you can tailor flood patterns for high ceilings, raked seating, or wide open floor plates.
· Accurate color rendering — selectable CRI 70–90 options to match application needs from general utility (CRI70) to color-critical sports and retail areas (CRI90).
· Robust IP65 rating with double waterproof protection (waterproof structure + high-resistance silicone sealing) for reliable operation in dusty or humid environments.
· Intelligent compatibility — supports 0–10V, 1–10V, DALI, and DMX512 dimming for integration with modern control systems and energy management.

Design & Reliability

The fixture uses a full die-cast housing with a finned heat sink and recessed airflow outlets that optimize convection cooling and extend LED life. Surface treatment uses electrostatic powder coating to resist high temperatures and weathering, ensuring long-term aesthetic and performance stability. The internal power supply provides instantaneous starts and a power factor over 0.98 for efficient, reliable operation.

Benefits

Switching to LED high-bay luminaires like the HDLS-100W lowers energy consumption and maintenance costs compared with traditional HID/HPS systems — LEDs offer higher efficacy, instant start, and significantly longer lifespans, reducing replacement cycles and downtime in commercial and sports facilities.
