Metal Halide & HPS to LED Conversion Guide
Metal halide and high-pressure sodium fixtures are energy hogs that take minutes to warm up, fade as they age, and need a lift to relamp. Converting to LED cuts energy dramatically and ends the warm-up and relamping cycle. This guide covers the switch.
Replace HID high bays and area lights with Stingray, Round Bay UFO, or Hammerhead LED fixtures to cut energy 50 to 75 percent, gain instant-on light, and move service to the ground.
Why Convert from HID
- Energy. LED delivers the same light for far fewer watts.
- Instant-on. No warm-up or restrike delay after a power blip.
- Maintenance. No more lift-based relamping; tubes swap from the floor.
- Light quality. HID fades and shifts color; LED stays consistent.
Choosing Replacements
Match the old fixture's job: HID high bays become Stingray or UFO high bays (see the high bay vs low bay guide); HID area and flood lights become Hammerhead fixtures. Size with the calculator.
Steps and Payoff
- Map existing HID fixtures and wattages.
- Select LED equivalents by output, not watts; see lumens vs watts.
- Confirm DLC for rebates.
- Calculate payback with the ROI guide.
Warehouses are a classic conversion; see the warehouse buyer's guide.
