RAB WHALE4H Field-Adjustable, Linear Washdown Vapor Tight — 265/225/145W Selectable — 3500K/4000K/5000K — Gray

The RAB WHALE4H is a 4-foot high-output field-adjustable linear washdown vapor tight fixture delivering up to 38,081 lumens with field-selectable wattage (265W / 225W / 145W, factory default 265W) and field-selectable CCT (3500K / 4000K / 5000K, factory default 4000K) via onboard switches. The WHALE4H shares the same 4-foot footprint as the WHALE4 but delivers significantly higher lumen output — suitable for high-ceiling industrial and commercial facilities requiring premium light levels. Operating on 120–277V / 50–60Hz with 0–10V dimming to 10%, the WHALE4H is UL Listed for Wet Locations, IP67 rated, IK09 impact resistant, and NSF Certified. Surge protection: Ringwave LN4kV / LN-GND 6kV. Rated for 100,000 hours, backed by a 5-year RAB warranty. DLC Premium listed.
