What is Dimmable LED High Bay Lighting?
Dimmable LED high bay lighting fixtures are fixtures that can dim using low voltage dimmers. This means there are typically 10 dimming steps available. The low voltage inputs are either 0-10V DC or 1-10V DC. The difference between 0-10V and 1-10V is that 0-10V allows for turning the fixture off when a 0V signal is sent.
Two dimming wires are included with the fixtures and are wired separately from the powered 3 wire inputs. You can daisy chain multiple fixtures together to dim a section of lights.
Dimming High Bays is also the mechanism of how motion sensors work. The motion sensor sends a signal through the dimming wires to brighten the fixture or dim the fixture, depending on whether there is activity in the area.
We also have 120 Volt LED High Bays.
