The cool new Sentina ZenLight ($40) combines modern technology with ancient Japanese design to create a tranquil and energy-efficient nightlight that automatically turns on when you enter a room and turns off when you leave. This stylish motion-sensitive light produces soft, peaceful lighting that's easy on the eyes through authentic Japanese Shoji rice paper sealed within the clear plastic case. It uses only 3W of energy to power 16 pro-grade LED lights that last virtually a lifetime and can be set to automatically come on at dusk as an ambient nightlight or adjusted to be always on, always off, or at 1, 5 or 10-minute increments before shutting off. Perfect for hallways, bathrooms, bedrooms and more. (via Michael Kiely)
