Powerful LED High Bay Retrofit — Up to 73% Energy Savings The Light Efficient Design 270W Enclosed Rated High Bay Retrofit (LED-8242M50D-HV) is engineered for facilities ready to make a serious upgrade. Designed to directly replace HID fixtures consuming up to 1000W, this retrofit solution delivers dramatic energy savings without the cost of a full fixture replacement. Simply swap the bulb — your existing enclosed high bay housing stays in place. Built for Demanding Industrial & Commercial Environments With a high-voltage rating of 277V to 480V, this LED retrofit is perfectly suited for large industrial facilities, warehouses, manufacturing plants, arenas, and big-box retail spaces where high-voltage electrical systems are standard. The EX39 mogul base ensures a secure, compatible fit in most commercial high bay fixtures. The enclosed-rated design means it performs reliably even inside sealed fixtures where heat and airflow are limited. Crisp 5000K Daylight Output for Maximum Visibility Operating at 5000K (cool daylight), this retrofit produces bright, clear light that enhances visibility, improves worker safety, and brings out true colors on the floor — critical in environments where precision and safety matter most.
