Set of 2 torches. Each take 2x 18650 batteries (provided).
It also comes with a dual battery charger (USB)
They are really bright and effective!
There is a push button on one end, that, as well as turning the torch on and off, it also does 3 brightness settings, strobe as well as an S. O. S signal.
On the other end, the lens slides forward and backwards, to change from the brightest, focused beam, to a still surprisingly bright wide beam.
There is also a clip on the torch for clipping on a belt or pocket.
It is very lightweight and strong.
A really handy torch, easy to carry, that covers most eventualities!
I can't accurately give the longevity of the batteries, as they still haven't ran out yet!
But I know that 18650s are a long lasting and powerful battery. And each torch has 2!
