LED Bulb Compatibility

Due to the lack of uniform standards in the expanding LED market, LED lamp (bulb) technology and performance currently varies greatly. This has made compatibility with dimmer switches a difficult issue to resolve for manufacturers. Lightwave dimmers have been purpose designed to automatically calibrate to individual lamp types to ensure that they are compatible with the latest dimmable LED lamps, and in this regard the dimmers are one of the leaders in their class. Whilst the majority of dimmable LED lamps perform very well from the moment that they are installed, some varieties of may require manual calibration, or additional lamps on the circuit to increase the total load. A minority of lamps may continue to function poorly even after calibration. To guarantee the best experience with dimmable LEDs, a good solution is to use the pre-tested bulbs recommended on our compatibility chart.

Our new chart is constantly being updated and expanded. If you do not see the lamp type that you require, please feel free to give us a call for extra advice.

As a general rule we do not recommend exceeding 60W of LED load per gang for Lightwave Smart and Connect Series dimmers (unless exceptions are recorded on the charts), but damage to dimmers may occur at levels below this if the LED lamps used are not not dimmable (always check the lamp spec) or incompatible, so we strongly recommend adhering to the compatibility charts..
