The STEDI ST3K 51.5" is the largest bar in STEDI's slim single-row range, with a low profile (51mm without brackets, 63mm with brackets attached) designed to fit tight spaces like front bars or grilles while keeping the factory look. It combines flood and spot beam technology using OSRAM OSLON® White LEDs across 50 emitters, sealed to IP68.

With 10,250 lumens and a beam reaching out to 778m, this is the long-range option in the ST3K range for large 4x4s and trucks that still want a slim, low-profile bar rather than a bulky double-row unit.
