Dabbled with several wind up devices and just find them a pain. The winding really doesn't store much energy in the battery. My lamp i have to charge up at home and don't even bother with the wind up function, even then it will hardly last for 4-6 hours let alone a long session. So having disposed of the cheaper option (battery wise) does anyone have any suggestions for a decent bivvy lamp that won't break the bank and will last a while? Any method of energy will do. Looking to spend around 20 quid tho i'll stretch to 30.
Cheers
