The Pinnacle of Performance By harnessing the power of Pure Drive technology, the entire ST4K Stedi range has been made to take full advantage of the input power, it is able to harness 97% of the input power and drive the 40, Osram Oslon LEDs. These LEDs have been hand picked by Stedi for their high luminous flux, their optical properties as well as their perfect, crystal white, 5700k colour temperature. Jack of all Trades The ST4K 22 Inch, 40 LED Light Bar brings together the strengths of both spot and flood reflector distributions. With a 8 Flood / 24 Spot / 8 Flood reflector array, Stedi are able to harness the light to deliver an amazing 663m at 1 Lux, with a 90wide flood beam. Built to go all night the extruded aluminium heat sink is finished in a UV and abrasion resistant powder coat to ensure your bar will NEVER discolour. Stedi have thrown down the challenge, drown your lights. With an IP68 rating it is dust and particle tight as well as waterproof up to 3 meters. Your 4WD will go under before these lights do!
