This is an upgrade to the standard incandescent bulb that comes with our night lights. We will substitute the standard bulb with this bulb. It is the new style "filament" type LED. It looks very much like an incandescent bulb, with a tall filament inside the bulb that emits light along its entire length. We had these specially made for us to have the same "warm white" 2700 degrees K. color temperature as an incandescent bulb. It does not have that harsh bluish green light that many LED's have, it looks really nice with our night lights! It runs much cooler, at .7 watts, it uses 1/10 the power of a regular bulb, and it is rated at 15,000 hours, or ten times the lifespan of an incadescent bulb.
