The Smart LED Desk Lamp from Satechi is the ultimate in energy-efficient desk lighting. It uses a bank of LEDs that use only 1/8th the energy used by an incandescent bulb and less than half that of a fluorescent bulb. A touch panel toggles the lamp through four brightness levels: study mode (brightest, bluest light), reading mode (bright, blue light), relaxation mode (dimmer, warmer light), and bedtime mode (dimmest, warmer light). (Click the image for a better view of the four modes.) The Smart LED lamp has flexible joints that allow you to bend the lamp to get the light exactly where you need it. It will provide 40,000 hours of light with a color-rendering index of 90. In addition to using less power, this lamp has no mercury or other environmentally damaging materials. There’s also a USB port on the back of the lamp’s base that can be used to charge your devices. The Smart LED Desk lamp is available in black or white for $99.99.
