Upgrading commercial facility lighting to high-efficacy UFO LED High Bays can lower electricity consumption by up to 70% while drastically improving foot-candle uniformity and worker safety.
UFO LED High Bay lights are compact, circular commercial fixtures built for ceiling heights between 15ft and 45ft. With luminous efficacies up to 170 lm/W, 0-10V dimming, and DLC 5.1 Premium listing, they're direct replacements for old 400W to 1000W Metal Halide fixtures and qualify for the biggest utility rebates.
1. What is a UFO LED High Bay Light?
Unlike old rectangular fixtures or traditional metal halide bell housings, UFO LED High Bays use a finned die-cast aluminum heat sink shaped like a flying saucer. This round design pulls heat away from the LED chips efficiently, keeping the lights running for over 100,000 hours.
A good retrofit does more than save energy, it flattens the light across the whole floor, not just in a bright circle under each fixture.

2. Metal Halide vs. UFO LED Replacement Matrix
Use the following sizing standard when retrofitting legacy HID lamps:
| Legacy Metal Halide | UFO LED Wattage Equivalent | Target Lumens | Recommended Mounting Height |
|---|---|---|---|
| 250W Metal Halide | 100W UFO LED | 14,000 – 17,000 lm | 12ft – 18ft |
| 400W Metal Halide | 150W UFO LED | 21,000 – 25,500 lm | 18ft – 25ft |
| 750W Metal Halide | 200W UFO LED | 28,000 – 34,000 lm | 25ft – 35ft |
| 1000W Metal Halide | 240W – 300W UFO LED | 40,000 – 51,000 lm | 35ft – 45ft+ |
3. DLC 5.1 Premium Certification & Rebates
Choosing fixtures certified under DLC (DesignLights Consortium) 5.1 Premium means they meet strict efficacy standards (over 140 lm/W) and support integrated controls. Utility companies across North America offer upfront rebates from $40 to $150 per fixture when you replace older, inefficient lamps with DLC Premium fixtures.
