I've become a fan of LED lights lately, although we had them as kids in the 80s for Christmas tree lights they've come a long way since then!
This torch looks like a good one at a decent price:
Tecxus Rebellight X90 Led Torch
Tecxus Rebellight X90 LED Torch
Measures 97 x 19mm, weight 100g
Always good to have a torch about the house!
