The ST4 Evolution is a hugely versatile LED light bar which at 8” in length delivers incredible lighting performance which belies its diminutive size. High-density 11W LEDs are carefully selected for their high ‘bin’ rating, and deliver 4,136 lumens. Advanced electronic design, combined with sophisticated thermal management systems, and ultra-reflective vacuum-metallized reflectors, harness the light output into a flood beam pattern optimized for both on and off-road use.

Performance aside, the ST4 Evolution is built to last. With a 5 year warranty as standard, and a lifetime guarantee on the ‘unbreakable’ polycarbonate lens, which is coated with a hardcoat lacquer to protect against any scratches, the lamp is capable of withstanding the harshest environments. An IP69K rating certifies the lamp will not be subjected to moisture or dust ingress, with additional counter-measures to ensure the unit remains fully contained even in the most extreme of temperatures and humidity. The full aluminium housing gives the lamp its strength and rigidity, while an e-coat pre-treatment provides automotive quality corrosion resistance. Dynamic drive modulation optimises light output considering the thermal conditions of the lamp (preserving the longevity of the LEDs).

The ST4 high performance LED light is DOT compliant for use on public highways where state laws permit it, please click here more information.
