Streamlight Sledge Features The Streamlight Sledge runs on two white LEDs rated for a 50 000 hour lifetime driven through a multi function push button switch with four output modes. Low delivers 100 lumens and a 35 meter beam for up to 13 hours Medium steps up to 300 lumens and a 58 meter beam and High reaches 600 lumens with an 85 meter beam for close to 4.25 hours of runtime. The THRO mode provides a temporary 1 000 lumen 110 meter burst for 60 seconds when maximum brightness is needed triggered by holding the button for three seconds while the light is on. That tiered output lets the user match brightness to the task rather than draining the battery on full power constantly. Built from tough polycarbonate thermoplastic with an aluminum faceplate and an unbreakable polycarbonate lens the Sledge is rated IPX4 water resistant and tested to 2 meters of impact resistance. The 45 degree tilting head lets the beam angle down without tilting the whole headlamp and the USB-C rechargeable SL-B26 battery recharges fully in about 5 hours. At 4.6 ounces with the battery installed it stays light on the head during extended wear. Backed by a limited lifetime warranty and serialized for positive identification the Streamlight Sledge is a dependable choice for hands free lighting in demanding environments.
