Light Emitting Diodes (LEDs) have emerged as a solid-state replacement for HID lamps. As implemented in the Christie EnteroTM LED rear-projection display systems this technology provides a number of distinct operational and performance advantages that solve many of the challenges of projection arrays in general, and video walls in particular.

Operationally, the prime advantages of LEDs are high reliability and long life. For example, reliability data from LED-manufacturer Luminus Devices based on several million device-hours of testing, predict median lifetimes in excess of 50,000 hours, potentially as high as 80,000 hours, under operating conditions typical in projection applications. This figure is far in excess of the expected lifetimes of HID lamps, which can vary from as low as 500 hours for some high-power Xenon lamps to as high as 10,000 hours for certain low-power, ultra-high pressure mercury-vapor lamps.
