With the choice of Constant Light or Energy Saving modes the iH9r lets you choose between focussing on brightness or battery life so you always have the performance you need. The option of red, green and blue light in addition to a standard white LED of up to 600 lumens makes this the ideal choice for a variety of uses both industrial and for general outdoor. The iH9r can be used as a hand held torch, or mounted to a helmet with the anti-slip head band. Using the included rechargeable battery which can be charged via the magnetic charge system, or two standard AA batteries, you'll never find yourself in the dark.
