In the bulb format, the driver is usually located inside the base of the bulb. Almost all LEDs make use of a driver as part of their construction, which is because LEDs mainly work on a low DC voltage whereas the electricity found in our power outlets is a higher volt AC.

The differentiating factor between these has to do with the driver they use. The reason for this is rooted in the difference between dimmable and non-dimmable LEDs. We have already established that you shouldn’t use non-dimmable LEDs on dimmer switches, but this answer isn’t very satisfying if you don’t know why this is. The Difference Between Non-Dimmable And Dimmable LEDs Photons (particles of light) are given off as the electrons and holes recombine. Electrons and holes cross the junction and combine. 5 Can A Non-Dimmable LED Ever Be Dimmed? Battery connected across the p-n junction makes the diode forward biased, pushing electrons from the n-type to the p-type and pushing holes in the opposite direction.4.2 The Lifespan Of The LED May Decrease.4 Consequences Of Trying To Dim A Non-Dimmable LED.3 Why Non-Dimmable LEDs Won’t Work On A Dimmer Switch.1 The Difference Between Non-Dimmable And Dimmable LEDs.
