At a glance

Solid brightness. No frills. Just reliable, industrial-grade light.
This 250W metal halide lamp pumps out 21,000 lumens in a neutral 4000K white — the kind that makes warehouses, gyms, and parking garages feel like somebody actually turned the lights on.
It slots right into your existing HID setup with a classic ED28 shape and E39 mogul base. Built for enclosed, dry-location fixtures. Works hard for 10,000 hours without needing attention.

• You’re replacing a 250W HID lamp in a high or low bay fixture

• Your fixture is exposed to wet conditions
