The Ultimate Light Bar. A Powerhouse of Performance.
The STEDI™ ST3303 PRO 39” LED Light Bar is the pinnacle of double-row lighting performance. A culmination of nearly a decade of innovation, refinement, and real-world testing, it represents everything that has made STEDI™ a global benchmark in LED lighting technology. Designed and engineered in Australia, the ST3303 PRO delivers overwhelming light performance and rugged durability in a class of its own.
Driven by 60 × CREE® XLamp XP-L HI emitters using SC5 Technology™, this behemoth outputs a staggering 65,700 raw lumens (33,600 effective) and a peak intensity of 919,681 candela. The result? A commanding flood and spot combination beam that projects far into the distance while delivering a perfectly balanced spread across the road shoulders.
