UFO high bays (also called round high bays) are used primarily in applications such as warehouses, gyms, factories, airports, and garages. In the past, metal halide bulbs are used in a circular fixture with a reflective cover to shine the light down onto the space below. Fast forward to the 21st century, and LED lighting fixtures are completely changing the lighting landscape with higher lumen output (brightness) and lower wattages to save energy and money and reduce overall burnout maintenance caused by the shorter lifespans of older technology. LED UFO high bays have become the “go-to” choice for builders, contractors, electricians, and project managers because of these considerable upsides.
When retrofitting older fixtures with UFO LEDs, understanding equivalency is essential. Many old metal halide bulbs/fixtures will consume much more energy due to the higher wattages needed to create the brightness required for the application. For example, a 300W HID should replace a high output 100W or 150W UFO high bay. Another consideration is the light given versus the ceiling height. Many older applications need to have suitable light in the first place due to poor design or incorrect product specifications. Our recommendations for lighting are reasonably straightforward. For every 10ft of ceiling height, it should match a UFO LED in 10,000 lumens. For example, if a ceiling height is 30ft high, we suggest using a fixture that outputs about 30,000 lumens. In this case, a 30,000-lumen institution would be our 200W UFO LED high bay. A ceiling of 20ft. would lead you to our 150W LED with an output range of about 22,000 lumens or so. Some customers are happy with using a 200W in a 20ft. setting (extremely bright) for extremely brightly lit applications.
Here is an easy wattage conversion list to make the shopping experience easier.
- 100W LED UFO will replace a 400W metal halide (HID)
- 150W LED UFO will replace a 500-600W metal halide (HID)
- 200W LED UFO will replace an 800W metal halide (HID)
- 240W-300W LED UFO will replace a 1000W metal halide (HID)
