LED CFL Replacement Bulbs

The pin configuration is only the beginning of a CFL-to-LED replacement: the lamp must also suit the ballast or approved bypass arrangement, fit the housing and direct light appropriately in its installed position. Narrow the search by the original format, including PLC replacements or PLL replacements, before comparing output and color temperature. For repeated maintenance purchases, record the full replacement model and compatibility details against the fixtures it will serve. Similar-looking bases and comparable wattage descriptions are insufficient to establish interchangeability, especially where a building contains several generations of fluorescent equipment.
