RAB ALED Field Adjustable Area Light 78W/90W/150W Type IV 3000K 480V Slipfitter Mount White (ALEDM4TSFYW/480)

This ALED Medium area light slips onto a standard 2-3/8-inch horizontal tenon and throws a Type IV distribution optimized for parking rows, driveway edges, and retail perimeters — a semicircular pattern that pushes light forward and to the sides without spilling behind the pole. The white die-cast aluminum housing carries a polycarbonate lens and holds an IP66 rating for dust and water ingress, UL Listed for wet locations.

Field-adjustable output steps between 150W, 90W, and 78W right on the housing, so one part number covers three light-level tiers without stocking separate SKUs. Wired for a 480-volt service, the fixture delivers up to 19,467 lumens at the 150W setting — roughly the useful output of a 400W metal halide head, using far less energy. The 0-10V dimming driver drops output down to 10 percent for off-hours light-level tuning when paired with a compatible dimming circuit.
