400W Metal Halide Replacements
Many older 400W high bays can be replaced with lower-wattage LED fixtures, but ceiling height and layout decide the right output.
Metal halide fixtures can create slow warm-up, dim work areas, color shift, failed ballasts, and frequent maintenance. Warehouse LEDs replaces older metal halide high bays, wall packs, and area lights with commercial LED fixtures matched to the building.
Every existing building is different. The walkthrough reviews fixture type, ceiling height, current brightness, access, maintenance issues, and how employees use the space.

Good lighting is easy to notice in person: brighter work areas, cleaner ceilings, safer movement, and a building that feels easier to operate.
