LED modules designed for household use usually contain internal drivers rather than separate, external drivers because they make replacing outdated lighting simpler. These include LED bulbs with standard screw-in or plug-in bases (E26 / E27 or GU24 / GU10 – see images below) or those that specify a line-voltage (120 volts) input. LEDs that typically require an external driver include cove lights, downlights, and tape lights, as well as certain fixtures, panels, and outdoor-rated lights. It’s simpler and cheaper to purchase a LED driver replacement than the LEDs. These bulbs are used for commercial, outdoor, or roadway lighting purposes.  Learn More Here!
