The Bulbcap is a lampshade, slightly more than a lightbulb.  The caps are directly pulled over the lightbulbs of up to 40 watts.  Any wattage can work when using economical lightbulbs.  The Bulbcaps can be fixed on hanging bulbs from the ceiling, or on standing lamps of any kind.  Mix and match various colors to create a collage of lights!

*Maximum 40watts**Luminescent caps contain special pigments that charge with light in order to glow for a short while in a green/yellow tone after the light has been turned off.
