Upgrade Your High Bay Lighting Without Replacing the Fixture The Light Efficient Design LED-8030M40-MHBC is a plug-and-play LED high bay retrofit engineered to replace up to 400W HID (High-Intensity Discharge) lamps — including metal halide — with no fixture rewiring required. Simply swap out your existing lamp and let your current MH ballast (up to 400W) do the rest. It's one of the smartest upgrades you can make for your facility. Designed for Demanding Industrial & Commercial Environments With its EX39 mogul base and upward-facing LEDs, this retrofit delivers bright, uniform 5700K daylight illumination ideal for warehouses, manufacturing floors, gymnasiums, big-box retail spaces, and distribution centres. The cool white colour temperature enhances visibility, improves worker alertness, and makes colours appear crisp and true-to-life. Significant Energy Savings, Immediate ROI By replacing a 400W HID system with this LED retrofit, facilities can dramatically cut energy consumption and reduce maintenance costs associated with frequent HID lamp replacements. The ballast-compatible design means zero downtime and zero fixture investment — just real, measurable savings from day one.
