I was in CostCo the other day ordering some new contact lenses (wearing my glasses spoils my good looks.....), and I stumbled across a 3-pack of pocket torches. As I wanted one for the car, one for the truck, and one for the kitchen drawer, I purchased said pack.
Bargain!! About 16 quid incl the VAT for 3 torches that have the batteries supplied too; 3 settings - 50% beam, 100% beam, and strobe function, selected by sequential click of the tail cap button. Very bright for their size.
There may well be brighter/more robust torches out there, but for near enough a fiver a pop with batteries, I reckon they're an absolute steal!! (and you won't weep when you lose one.....)
Get 'em bought.
