Why You Might have A Low Load Dimmer Switch?

For those who plan on buying dimmable LED it is worth checking their compatibility along with your existing dimmer switches. Dimming an LED Bulb will not be as simple as dimming a halogen bulb where a simple change in voltage will suffice. Rather, the switch has to compensate for his or her constant current and low wattage.

The first thing to recollect is that there are two main forms of dimmer switch; leading edge, often known as triac dimmers, and trailing edge. These switches usually are not interchangeable. The internal driver on LED Bulbs require a trailing edge dimmer switch with a purpose to work.

Standard switches are designed to operate with relatively high loads, typically between 40 and 200 watts. With a purpose to function correctly the circuit load, the combined wattage of all the bulbs on the dimmable circuit, must meet the minimum load stated on the switch. The circuit load may be calculated by multiplying the number of bulbs on the circuit by the person wattage of every bulb. If the resulting figure is lower than the minimum load on the switch you run the chance of under-loading it, which can cause problems similar to limited dimmability and flickering.

While halogen bulbs, which use about 50 watts each, don’t have any problem achieving the minimum load on a dimmer switch (the major concern here is overloading), it can take several LED Bulbs before the minimum load is reached. This may not be an issue in case you are running ten or more light bulbs on the same circuit, but if you’re using less you will need a low load dimmer switch.

Low Load Switches are designed to compensate for the low energy requirements of LEDs. Because the name suggests they’ve a much lower minimum load than standard switches allowing them to run fewer dimmable LED Bulbs on a single circuit.

Most switches are designed with an in-built micro-processor that gives protection against overloading. Because of this should you mistakenly connect too many bulbs or transformers to your switch it’ll protect itself by automatically dimming the lights or by shutting down altogether.

If you would like any more information on dimmable LED or low load dimmer switches please leave a comment and be sure you consult an professional electrician before attempting to change any electrical connections to avoid any possible accidents or mishappenings.
