Is leading edge dimmer suitable for LED?

Leading edge dimmers are suitable for inductive load, for example magnetic low voltage transformers; and resistive loads like incandescent light bulbs. They are generally unsuitable for LED light bulbs.

What does leading edge mean on a dimmer switch?

Leading edge dimming cuts of the front edge of each waves’ half cycle. Conversely trailing edge dimming cuts out the second half of each waves’ half cycle. Trailing edge dimmers are now the more popular of the two types.

How many LED lights can I put on a dimmer switch?

A good rule of thumb is to allow 100W for each LED fixture so in this case, the 600W dimmer can handle only six LED fixtures. If you are meeting all of the electrical requirements of the dimmer and you are still having flicker issues, you can try adjusting the low-end trim.

What is a leading edge LED?

There are two types of dimming modules, leading and trailing edge, which we will look at below. LEADING EDGE. These dimmers were originally used for dimming incandescent and halogen lamps. Due to their original use, these dimmers have a high minimum load, making them less useful for low energy lighting such as LEDs.

Can dimmers damage LED lights?

The simple answer is yes – there can be a fundamental incompatibility between the LED driver and the dimmer which leads to spurious and often very large current pulses into the driver. Oscillogram 1 shows the measured LED voltage (red) and current (yellow) of a GU10 LED lamp being dimmed with an incompatible dimmer.

Are LED leading or trailing edge?

Leading-edge: inductive loads (e.g. magnetic low voltage transformers), resistive loads (e.g. incandescent). Trailing-edge: capacitive loads (e.g. electronic low voltage transformers, LED drivers), resistive loads (e.g. incandescent).

What happens if you don’t use an LED dimmer switch?

If you install a non-dimming LED bulb in a circuit with a dimming switch, it will likely operate normally if the dimmer is at its 100\% or fully on. Dimming the bulb, will likely cause erratic behavior such as flickering or buzzing and ultimately may cause damage to the bulb.
