If you’re on the prowl for energy-saving lighting solutions this Satechi LED Desk Lamp is a very nice combination of style, functionality and cost savings. The lamp features easy-to-use touch screen controls as well as a variety of light-intensity modes and brightness levels.
The desk lamp’s modern, minimalist design has a nice clean look and consumes only 1/8th of the power of an incandescent lamp and less than half of the power of a comparable fluorescent lamp. The lamp’s LED has a 
lifespan of over 40,000 hours with a color rendering index (CRI) of 90. And, unlike CFLs, it contains no mercury or other environmentally harmful substances.
The design features several flexible pivots to ensure it fits into any desk space or position. Additional features include an energy-saving timer function that can turn the lamp off after a period of inactivity and a USB port that enables you to charge various USB-chargeable devices by plugging them into the lamp.
