Second-generation LED high-bay fixtures typically reduce energy consumption by 60-70% compared to metal halide and high-pressure sodium (HPS) lighting. For an industrial facility running 50 fixtures of 400W metal halide replaced with 150W LEDs at 12 hours per day and 300 days per year, annual savings usually fall between $5,000 and $9,000 depending on the local electricity rate. Industrial retrofit projects generally reach payback within 12-24 months.
For factories operating 12 hours per day, industrial LED retrofit projects typically pay back in 12-18 months. Facilities running 24 hours per day, such as continuous manufacturing and cold storage, often reach payback in 6-12 months because the higher operating hours accelerate monthly energy savings. Projects with payback under 24 months are considered excellent investments given the 50,000+ hour LED lifespan.
Ceiling height directly determines the LED wattage and beam angle required. For 6-8 meter ceilings, 150-200W LED high-bay fixtures deliver optimal lux levels. For 8-12 meter ceilings, 200-400W LED high-bay fixtures are recommended. For ceilings above 12 meters, 400W and higher LED high-bay or stadium-grade fixtures are needed to maintain adequate illuminance on the working plane.
