BLACK DIAMOND COSMO 300 £30

The Cosmo 300’s real selling point is its IPX8 rating (tested to operate at least 1.1m underwater for 30 minutes), making it a very waterproof product – perfect for Britain’s rainy climes. Maximum output is 300 lumens with 74m range, or for mid-distances the 150 lumens option is ideal. The classic design features an adjustable headband and a simple, hinged headlamp with just two buttons.

VERDICT An excellent all-rounder with a great price and superb waterproofing – essential in wet winter weather.
