Gelert 0.5W Led Headlight.
The Gelert 0.5W LED Headlight is powered by AAA batteries; it usually runs off two, but when required it can run off just one. This is particularly useful for power saving or if there's a limited supply of batteries. The casing is water resistant for use in the rain and has a soft feel rubber textured finish. An adjustable head strap ensures a good fit for all sizes of user and the torch angle can be altered to optimize effectiveness during different activities.
