The Pinnacle of Performance. Compact Power, Unlimited Potential.
The STEDI™ ST4K 8” Double Row LED Light Bar proves that size isn’t everything. Designed to punch well above its weight, the ST4K 8” delivers a remarkable 363 m beam distance at 1 Lux, lighting up the road shoulders 55 m to each side. With a compact yet powerful design, this bar is the perfect choice for those needing serious performance from limited mounting space.
