Multiple channels solid-state circuits provide electronic redundancy, the LED Headlight include dual LED drivers and dual LED-Boards. If one channel fails, the second remains “ON” until the headlight is replaced.
The advanced electronics limits electro-magnetic emissions, and protects against Over/Under voltage, Over/Under current, reversed voltage, fast transient, and power port surges.
Forward-Cooling PAR46 Subway Car LED Headlight, 14 watts, 37.5 VDC, polycarbonate lens with an anti-abrasive hard coating, Mogul End, Brass-Nickel Plated Prongs inside an Epoxy-Potted Aluminum Housing, Max O/A Length 4-3/8”, 5 Year Warranty.
