Performance & Coverage

The Grote 61291 LED WhiteLight recessed-mount dome light is engineered for interior illumination in heavy-duty trucks and commercial vehicles. Its six high-output LEDs deliver 940 lumens of clean white light while drawing only 1.75 A at 12 VDC, with a controlled inrush of up to 2.7 A at start-up. The wide-spread optic pattern projects wall-to-wall coverage, making it an efficient, low-current alternative to fluorescent fixtures. Measuring 18.26 in x 6.25 in x 1.75 in, this low-profile, flush-mount design integrates cleanly into headliners and compartments, maintaining clearance and minimizing snag points in cabs, sleepers, and cargo areas. Rated for operation from -40°F to 122°F, it performs consistently across diverse climates.

Rugged Construction & Protection

Built for vocational and fleet duty cycles, the 61291 combines an aluminum housing, acrylic lens, and plastic back panel for durability with reduced weight. Encapsulant-potted electronics shield the circuit board from vibration and environmental stress, while a built-in automatic thermal protection device and self-resetting internal cut-off switch safeguard the lamp under over-temperature or over-current conditions. The reduced-diode, standard-output design maintains uniform illumination with fewer emitters, supporting efficiency and reliability. With a 50,000-hour rated life and a 3-year warranty, this interior utility light lowers maintenance burden and battery load over time, making it a dependable choice for trailers, box trucks, work vans, and tractor interiors where uniform, reliable white light is required.
