5000K 210W LED High Bay Fixture Gen 3

The Keystone KT-HBLED210-3F-850-VDIM /G3 LED High Bay delivers powerful, energy-efficient illumination for commercial and industrial spaces that demand reliable overhead lighting. Part of Keystone's Generation 3 High Bay series, this 210W fixture produces 33,600 lumens at an efficacy of 160 lm/W, with a 5000K color temperature and CRI greater than 80 for accurate color rendering in warehouses, gymnasiums, manufacturing floors, and other high-ceiling applications. Built with an architectural-grade compact design, the fixture features a bent steel housing with a polycarbonate frosted lens that eliminates glare while maintaining high light output. The frosted lens and 90 deg beam angle work together to provide broad, even coverage across large open areas. This fixture operates on a universal 120-277V input and includes a Keystone 0-10V dimming driver, dimmable down to 10% with dim-to-off capability - ideal for pairing with occupancy sensors or daylight harvesting controls to reduce energy costs further. A built-in sensor receptacle allows for easy screw-in installation of optional PIR or microwave occupancy sensors (sold separately), and the fixture is compatible with Keystone SmartSafe emergency LED drivers and 480-277V step-down transformers. Durability features include built-in 6kV surge protection and an LED chip rated for L70 >100,000 hours at 25 deg C/77 deg F ambient fixture temperature. The fixture is UL Listed 1598 and suitable for damp locations, with an ambient operating temperature range of -20 deg C/-4 deg F to 50 deg C/122 deg F. V-hook and chain mounting accessories are included for straightforward installation. Note: This fixture is not suitable for environments with caustic or corrosive chemicals present (including sulfuric or hydrochloric acids, sodium hydroxide, chlorine, acetone, methyl ethyl ketone, ammonia, or hydrogen peroxide).
