The Littlite LED Lampset with three-way rotary switch enables user to toggle between white light and red light output. It provides even illumination over a wide area, specifically designed to evenly illuminate consoles and control panels. Some LED lights produce a very bright "spot" of light, but this is useless for illuminating a broad work space. This is not the case with the Littlite LED. The Littlite LED is designed to be efficient - most of the power used by the Littlite LED is delivered to the LED's, not a resistor. The LED's in the Littlite LED are not overdriven and may be expected to remain useful for over 10000 hours of operation. Littlite lampset's have a 12" cord set terminating in a 2.1mm socket. GXF-10 power supply has a six-foot cable terminating in a 2.1mm plug.
