Go to Tesco and get a blue and white 7 inch long (18cm) Toshino “Living Simplicity” flashlight. It is re-chargeable, lightweight, and the damn battery just won’t quit on these things. It’s an LED light with either 3 or 6 LEDs you can turn on at a time. I used one for 5 hours of snake hunting, then, as a test, turned it on 36 hours ago – on full 6 LED – and it is STILL WORKING. It is not as bright as it was with full-charge – but the fact that it’s still working after 41 hours of use is incredible.
I think it cost 160 THB.
