Sanyo is quite successful with their range of pre-charged rechargeable batteries called Eneloop. I use them for all my gadgets at home.
Today Sanyo announced a cool new gadget in the Eneloop line with the ENL-Y1S Eneloop Lamp.
The Eneloop Lamp a very stylish rechargeable interior light that becomes a flashlight if you lift it up. The Sanyo Eneloop Lamp uses a contactless charging system and has no metallic contact on the product body, giving it a nice exterior appearance.

The eneloop lamp can be used 3 different ways: as an Interior Light that gently lights up a room from a table top, floor, etc. with a white lamp (2 modes to choose from: Clear Mode (high) / Fade Mode (low)); as a 'Healing Light' that creates a healing ambience with a blue lamp in a space like a bedside (Healing Mode (continuous) / Flicker Mode (Flickering)); and as a Flashlight that comes on automatically when the unit is picked up due to a built-in acceleration sensor.

High-luminance LEDs are used for the light source. A white lamp lights up the surrounding space clearly in Clear Mode and may be used as a night-light in Fade Mode. A blue lamp that creates a healing ambience can be switched between Healing Mode for continuous lighting and Flicker Mode for gently wavering brightness. The lighting type can be selected to match the room ambience or personal mood.
When the lamp unit is tilted by 90 degrees or more, a built-in acceleration sensor senses it and the flashlight automatically turns on, making it possible to quickly obtain a light source in an emergency situation like a midnight earthquake without looking for a flashlight, as well as being able to use it as a daily-use handy light.

This very cool lamp will go on sale on September 11th. There is no pricing yet.
