Truck-Lite’s Super 80 LED interior trailer lamp with infrared motion sensor is similar to the company’s 80251C but eliminates the switch by its ability to be activated automatically when motion is recognized — or turned off subsequently. Perhaps a small bonus but a real one in the operator’s daily routine.

The LED Dome’s IR sensor, which compares changes in heat coupled with motion, can sense movement up to 10 ft away from the lamp surface. The lamp is designed to stay on through 5 minutes of inactivity before automatically shutting off, reducing power consumption.

The lamp sports a die-cast aluminum housing and a polycarbonate lens. The near flush mount design is 1.1 in. thick, compared with 1-5/8 in. for fluorescents, and thus leaves a little more clearance for loads or loading equipment. Retrofit or replacements are said to be quick and easy with a recommended cut-out of 16×4 in. A new potting material completely encapsulates the LEDs’ circuit board to ensure resistance to shock, vibration and fluids from cleaning activities.

Most trailers supply between 9 and 11 volts, but Truck-Lite says its Super 80 will function at full brightness from 7V-16V. Standard fluorescent lamps don’t work below 10v. The lamp’s 10 LEDs will reach full brightness at 9.5v, thus eliminating problems of low voltage.
