It’s a 1 watt LED lamp called the Havaleena by Tayo Design Studio. These lights only require three AAA batteries to run, and fully charged batteries provide 20 hours of illumination. Each light comes with four colored filters and they are priced at $59.
We featured some LED candles from Phillips previously but these lamps are available for only $9.95. The LEDs inside this lamp simulate a real candle. It’s powered by three rechargeable or regular AAA batteries. Available from CB2. Found via Better Living Through Design.
