Yes and No. First, not all LEDs are dimmable. The driver must be designed to allow dimming. Secondly, you must purchase the right type of dimmer. Most retail stores now carry dimmers specifically designed for LED bulbs. Please note, if you purchase a non-dimmable LED bulb and try to dim it, it will cause the bulb to fail and also void the warranty. Some of our industrial and commercial LED fixtures (high bays, floods, area lighting, retrofits) work with a 0-10V dimming system. 0-10V dimming requires special wiring and a special type of dimmer. The two most common types of dimming is: 0-10V low voltage and Triac dimming.
