The Hollis Micro Light is incredibly tiny -literally a size of a key ring and certainly small enough to carry in your pocket with minimal space, but bright enough for a backup.
From its size it's hard to believe it actually packs 55 Lumen, with a burntime of 1.2 hours and with the double o-ring sealing it is depth rated to 300'. The single AAA alkaline battery is included with the torch.
The torch has a handy tie-point at the rear for attachment.
