A colorful hat for your lightbulb. If a regular shade just won't work or you want something a little less stark than a single bulb hanging from the ceiling, the bulbcap may be it.
Available in six different colors , these simply slide over a regular bulb. Special pigments in the material keep the glow on for a short while after turning off the light. Think glow in the dark stars on the ceiling of a kids room.
