The 4-inch member of Black Oak's Pro Series 3.0 double-row family. Double row means two stacked rows of LEDs in one housing, which buys output without making the bar any longer — useful when you only have four inches to work with.

Flood optics, so it spreads rather than reaches. At this size that is the right call: a 4-inch spot does not have the aperture to throw meaningful distance, but as a wide fill light tucked into a bumper opening, an A-pillar or a rack corner it earns its place.
