# Incandescent light bulb symbol Incandescent light bulb symbol that can be illuminated with 10mm (normal) or 12mm (most RGB) LED stripes, with room for a controller unit. The 12mm Version also fits most RGBW LED stripes so you have lots of options for some cool wall lights. The power cord opening should be big enough for most normal sized power cords. I left room for a small PCB, so there are lots of ways to control those lamps. I used an ESP8266 to control my RGBW lamp (the blue one) via my smartphone.
