Coast Rechargeable HP7R
Not the cheapest option, but it’s the complete package. This comes with a spare lithium-ion power pack, as well as standard alkaline batteries. The USB charge lead has mains and 12V adaptors, plus a neat cover for the socket. It oozes quality, with a sliding collar letting you shift the bright LED easily between wide and narrow beams. And this top performer was still working at the end of our 10-hour test.
