51.5 Inch 50 LED Slim LED Light Bar - Part Number: LEDST3K-50L
The STEDI ST3K 51.5 inch is a slim-line LED light bar running 50 OSRAM OSLON LEDs in a 10 flood + 30 spot + 10 flood reflector layout. STEDI rates the beam at 1 lux at 778m, with a 50 degree wide beam and a 5.8 degree spot, packed into a low-profile bar that sits neatly on a bull bar, roof rack or grille mount.
Colour temperature is 5700K true white, and STEDI's Pure-Drive circuit sends 97 percent of input power to the LEDs. The housing is finished in polyester UV and abrasion resistant powder coat, a pressure equalisation vent protects against water, dust and contaminants, and the bar is IP68, waterproof to 3 metres, with protection against EMC and RFI interference. The profile is just 51mm without the side brackets and 63mm with them.
STEDI's Easy-Fit high beam plug and play harness with H4 and HB3 adapters is included. Out of the box you may hear a rattle: STEDI explains this is the captive nuts in the end caps for the side brackets, and it stops once the brackets are fitted and tightened.
