NICOR HML1150U40A HML1 130W Linear LED High Bay 4000K 20574Lm 120-277V 86 CRI 0-10V Dimming White

Nicor’s HML1150U40A is a high-performance, LED high bay designed for rugged industrial and commercial spaces such as warehouses, gyms, and manufacturing facilities. With a compact 10x14 inch footprint at lower wattages, this fixture delivers substantial light output suitable for tall ceilings and large work areas, while supporting single-person installation. The unit is DLC-listed (including DLC Premium) and UL-listed, underscoring its compliance with common specification requirements for quality and energy performance in professional settings. The 4000K color temperature provides a neutral white light, and the 86 CRI helps ensure accurate color rendering for task visibility. The fixture supports 0-10V dimming, enabling compatible lighting controls to adapt illumination levels to varied tasks and occupancy patterns, which can contribute to energy savings and workplace comfort. Its white, durable finish and ceiling-mount design make it suitable for a range of installations where a robust, maintenance-friendly high bay is needed.

From a construction and performance standpoint, the HML series features a single-piece cast aluminum housing designed to withstand demanding environments, while maintaining efficient thermal management to maximize lumen output. The model’s specifications show a reported lumen package of 20,574 lumens and a luminance efficiency of approximately 141 lumens per watt at 147 watts, indicating strong output relative to input power. The fixture is intended for indoor use in damp locations and is not rated for wet locations or hazardous environments, which is important for planning installation in spaces with humidity or washdown needs. This high bay is offered with a package that is listed as a single unit, suitable for ceiling mounting, and is compatible with standard electrical supply within 120-277V, enabling flexible installation across different facility layouts.

When selecting lighting for industrial facilities, consider ceiling height, aisle arrangement, and control strategy. The HML1150U40A’s 4000K color temperature and high CRI support clear visibility for work tasks, while dimming compatibility allows integration with sensor-based or daylight-harvesting systems where permitted. The product is RoHS compliant, which aligns with broader sustainability goals, and its DLC certifications indicate alignment with energy-efficiency program requirements in many markets. Packaged as a single unit, it is ready for ceiling-mount installations and straightforward replacement in existing high-bay layouts.
