The FeatherBrite Moonlight bulb helps relieve the stress of night for those birds who experience "night fright". The bulb has 3 blue LED bulbs encased in a frosted white globe. It has a candelabra base and can be purchased with an adapter that can be used with a standard socket if needed. The bulb gives off a soft blue light that is very calming. Operates using only .6 watts of electricity. PLEASE SPECIFY IF YOU NEED ADAPTER. We have discounted the bulb if it is replacement not needing an adapter. Adapter NOT included unless requested.
