Stretch Light RT5064 Torch.
This versatile torch converts to a lantern when you slide the top away from the body, making it ideal for walking or working. In torch mode it projects a focussed, high intensity LED beam through a magnifier lens and, as a lantern, it provides a useful ambient light in a room or tent.
The body is machine crafted aluminium and the three AAA batteries (supplied) will last for up to three days. It's 12.6cm long and weighs just 91g.
