Dimming For LED Lighting

WHAT IS PHASE DIMMING?

There are two types of Phase Dimming: Leading Edge Dimming and Trailing Edge Dimming
Leading Edge dimming is sometimes called Forward Phase or TRIAC dimming
Trailing Edge dimming is sometimes called Reverse Phase or Electronic Low Voltage Dimming.
There is a massive installed base of phase dimmers which is why they are so popular.
There are no additional wires on a Phase Dimming driver. The dimmer is wired in line with the output of the driver.
Phase dimming is only available in 120V input

WHAT IS 0-10V DIMMING?

This dimming type is used in most new construction and commercial applications.
There are extra wires (usually grey and purple) on the driver that hook up to the 0-10V dimmer.
9V is the maximum light level and 1V is the minimum light level.
0-10V dimming is available in universal 120V-277V input.
