Have you considered the wind-up variety - which you can recharge yourself

There is also a torch which can be shaken. It comprises a tube with a
fixed magnet at each end. In the tube is a third magnet which is free
to move. Around the tube is a coil. Shake the torch and it charges a
capacitor which in turn powers the light.
