Hand winding LED Torch replaced with green LEDs

The three white LEDs seen in the previous picture where unsoldered and replace with 3 ultra bright green LEDs. The green LEDs are brighter firstly because the human eye is actually more sensitive to green light and also the white leds are not actually white but slightly violet ( this is because ultra bright white leds are actually ultra violet LEDs with a chemical compound that change the UV into white light ).
