TSEXES — 400W LED Corn Light (Mogul Base Compatible)
TSEXES presents a 5000K LED corn light designed to replace 400W metal halide/hid fixtures with an E39 mogul base. The LED option promises up to 50,000+ hours of life, high lumen output while enabling ballast bypass and simplified installation. It provides a high-efficiency alternative for open fixtures, enclosed luminaires, and high bay environments seeking improved energy savings and reduced maintenance.
Buying Guide: Key Considerations For 400W Metal Halide High Bays
- Fixture compatibility: Verify ballast type and whether ballast compatibility or ballast bypass is required when replacing HID with LED or swapping lamps.
- Beam angle and lens design: For open high bays, aim for wide beam distribution; for enclosed fixtures, ensure lens and housing tolerances suit the space.
- Color temperature and CRI: Common HID options are around 4000K; LED replacements often offer 5000K with high CRI for true color rendering in workspaces.
- Lifespan and maintenance: LED replacements typically offer longer lifespans than traditional 400W MH lamps, reducing maintenance cycles in hard-to-reach locations.
- Water and dust ratings: In wet locations or outdoor bays, select fixtures rated for wet or damp locations to ensure reliability and safety.
- Energy efficiency: LED options can dramatically reduce energy use compared with 400W HID lamps, improving energy bills over time.
- Installation ease and retrofit costs: Consider the total cost of ownership, including ballast bypass, fixture replacement, and any wiring changes required.
- Color rendering in practice: Higher CRI (close to or above 80) helps workers distinguish colors clearly, improving safety and productivity.
