The manufacturer decided to leave out the feature: it simply was not included in the circuitry. Why aren't some LEDs dimmable?īut why are some LEDs not dimmable at all? Simple. Simply connect the two output wires from the power supply to the dimmer unit, and. Waveform Lightings FilmGrade LED Dimmer, for example, includes DC plugs on both ends, allowing you to assemble everything in a matter of seconds without any tools.
#WHAT DIMMER FOR LED LIGHTS DRIVER#
This driver determines how the LED will react to different types of dimmers: incandescent phase control, leading-edge, trailing-edge, three-wire Lutron, or 0 to 10V dimmers.Īnd just because one LED dims just fine with one type of dimmer, that doesn't ensure it will work with others. DC PWM dimmers are typically very simple to assemble and connect to the power supply and LED strip. The sheer number of scenarios is due to LED bulbs having much more complex circuitry inside, referred to as the driver. This happens when the applied voltage (or the average of the applied voltage) drops below the minimum voltage required to power the LED. There is also a chance the LED works fine but shuts off or "drops out" below a certain brightness level. Flickers at specific or all dimmer levels.
If you use an LED bulb with an incandescent dimmer switch, you may find that the bulb: The same isn't always true with LEDs, however. Adjust the voltage applied by raising or lowering the dimmer and the brightness of the bulb will change accordingly. With incandescent bulbs, dimming is simple, since the brightness of a the bulb is directly related to the voltage applied. Hums, flickering and other dimming problems Unlike incandescents, all of which dim indiscriminately, LEDs either dim or they don't. In many cases, your existing incandescent dimmers won't play nicely with newer LED bulbs. If you're shopping for LEDs, there are many options to choose from - and dimmer compatibility only complicates matters.Įven if you pick the proper color temperature, lumens rating and a desired beam angle, you might run into another snag: dimmers. LEDs that are incompatible with dimmers tend to flicker.
