Light Emitting Diodes (LED)

Daktronics recommends LED displays employed in ITS applications use high-quality, latest-generation AlInGaP (aluminum, indium, gallium, phosphide) technology to maximize visibility. AlInGaP LEDs ensure the display consumes less power yet produces light brighter than obsolete fiber optic, incandescent bulb, and reflective disk displays.

For maximum LED lifetime brightness, Daktronics recommends the LED manufacturer's specifications always be followed when determining display drive current, which in most cases is 30 milliamps.
