400W metal halide fixtures are common in older commercial buildings
Warehouses, shops, gyms, exterior walls, and parking areas often still have 400W metal halide fixtures. They may still turn on, but the usable light can drop as lamps age and lenses get dirty.
LED replacement is not just matching watts
A 400W metal halide is not replaced by another fixture simply because the wattage sounds close. LED output, beam angle, mounting height, fixture spacing, and the work area decide the right replacement.
Maintenance savings can be a major reason to upgrade
Metal halide lamps and ballasts can create recurring service calls, especially in high ceilings or exterior poles where lift access is needed. LED replacement can reduce that headache when the fixture is selected properly.
