Looking for recommendations on 921 style LED bulbs need about 25 and want bulbs that won't cause interference with TV or radio but won't cost me a furtune.
Get panel style with aluminum backing. There's just a plastic plug with wires that goes in the 921 socket.
Aluminum backing is very important IMHO. Despite the common belief LEDs don't generate heat, that is only true for indicator grade. Heat kills LEDs, so keeping them under 50c will lead to the longest life.
