The STEDI ST3K 21.5" is a low-profile light bar (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 20 emitters, sealed against dust and water to IP68.

With 4,100 effective lumens and a beam reaching out to 493m, it's a solid mid-range option for grille or bumper mounting where you want genuine driving-light distance in a slim housing.
