Electrifying Performance At the core of the ST-X 50 Inch Light Bar you will find 20 x 15W LEDs with reverse facing emitters that push out a staggering 10,000 Lumens. In a stunning 5000K colour temperature, the light is pure white and easy on the eyes. The 30 degree horizontal beam pattern is optimised for medium to long range illumination, all the way out to 1 lux at 941 meters. The ST-X 50 Inch delivers very little light in the first 80 meters, making use of your vehicles lights. The 15 degree vertical spread means minimal light wasted and avoids that annoying reflection from road signs. A Cut Above The Rest The built in amber (2700K) or white (6000K) DRL / Position Light function keeps you visible day or night. The amber light is perfect those early mornings and for cutting through fog and bad weather. Amber lights can be better in the rain as it penetrates water, rather than reflecting off it - perfect for judging puddles and pools after a drenching! Stedi have strategically hidden the separate positioning light LEDs, this offers stunning uniformity of light distribution within the light bar. Near Invisible Frame The Stedi name has become synonymous with cutting edge, innovative design. Stedi have proven this once again with their new edge to edge bonded lens. It results in a clean looking edge without the thick outside bezels with hardware and fixings. The ST-X light bar range is absolutely stunning from every angle. Stedi uses a hooded reflector design and they call it "High Beam On Steroids". The ST-X range excels in high speed, highway applications. It excels when mid to long-range visibility is critical. The horizontal and vertical light spread significantly minimises the reflection from road signs and the pure white colour is great on the eyes. The ST-X range is a cut above the rest.
