Originally LED lights could not be dimmed and wouldn’t work with standard dimmer switches. However, now many types of LED lighting including white and RGB strip lights come in dimmable models that can be dimmed in two main ways: with LED dimmer switches, or using dimmable LED drivers and standard dimmer switches. These two options offer smooth, seamless dimming from 0% to 100% brightness, and mean that anyone can install conventional dimmable LEDs or even dimmable color-changing LEDs anywhere that they want LED lighting and the option to dim it.
One of the benefits of dimmable LEDs and LED dimmers is that they use a different dimming technology than most traditional dimmers, and they interact with LED technology itself in such a way that dimming LEDs has absolutely no adverse impact on the life of the lights. On the other hand, dimming has little to no benefit in terms of decreased energy consumption, unlike dimming incandescent bulbs, which can cut their energy usage. But this isn’t an issue for most because LEDs consume such low amounts of electricity that for many fixtures there isn’t much room for meaningful decrease.
Thanks for this info., but I am still getting frustrated with this LED dimming thing. I don’t under stand why all 12v DC LED’s can’t be dimmed? When I vary the voltage to a single LED;it dimms! Why are bulb suppliers trying to sell me ” dimmable” (MR16 4W) bulbs. When you consider the economics of PWM controllers, WHY WOULD I NEED THIS DIMMABLE BULB ? Again, I’m talking 12v DC; and which one of your controllers would I use; and what is it doing for me. If there is any advantage to these new “dimmable” bulbs, please enlighten me !
Thanks
Terry
