How Many Amps Does your UFO LED High Bays Draw?

LED UFO high bay lights use fewer amps than HID (Metal Halide) fixtures. The formula to calculate amp draw is:

Watts / Volts Draw = Amp Draw.

Here are some examples with 300-Watt lights:

300 Watts / 120V = 2.5 amps
300 Watts / 277V = 1.08 amps
300 Watts / 480V = 0.625 amps

Comparatively speaking, the 1000-Watt HID fixture is designed to replace (including 15% ballast draw):

1150 Watts / 120V = 9.58 amps
1150 Watts / 277V = 4.15 amps
1150 Watts / 480V = 2.39 amps

This is why it is more efficient to run lights at a higher voltage. You can install more lights on one circuit.

Do You Sell Reflectors for these Lights?

Yes, but you won’t need them. Reflectors work great for non-directional light sources, like Metal-Halide. The lumens they produce need to be “collected” and then reflected back down to the floor. LED Lights are already directional, so reflectors are not needed. We do offer several reflector options if you need one.

How Can I Calculate Light Coverage at X feet Height?

The UFO lights we offer have interchangeable optics. Like 60, 90, and 120 (Standard) degree beam angles. Each will produce a different result. Coverage is also affected by how close the fixtures are together.

Are there any rebates or incentives available for purchasing UFO High Bay LED Lighting?

There are. However, rebate availability and amounts are determined by local utilities. So it’s up to them to decide what rebates they are willing to provide, what the rates of rebates are, and when the rebates can be applied for. So while our LED High Bay Lights are DLC Listed and/or Rebate eligible, there’s no guarantee you will get a rebate.

However, without rebates, many of our lights pay for themselves in 6 months to 2 years, depending on electricity rates and usage. So, you might not need a rebate as the ROI is very positive and short.

Do Your Lights have Power Cords? How Long are They?

Standard whip sizes vary from fixture to fixture, ranging from 3 feet to 6 feet. All the power cords are bare-ended and do not include a plug. A plug can be added if that’s what you need.


How easy is it to Install your UFO LED High Bays?

It’s an easy install process. We provide all the instructions you will need. Any qualified electrician should be able to install and wire UFO High Bays.

There are two main mounting options – eye hook mount and pendant mount. Eye hooks clip in. So if you are replacing an existing HID Fixture with an eye hook, this is a very simple installation. Same with the pendant mount, they will screw right into the existing conduit pipe.

How do I Wire a UFO LED High Bay?

Wiring UFO High Bays is simple. Our wire whips contain three wires – line, neutral, and ground. This is a very easy connection for a qualified electrician to make an easy installation with these fixtures.
