..to modify my Dive light Part 4 (Light Test)

I could not use the light for too long due to the heat produced. Therefore, just a short 5 minutes test.
About 1 meter from the floor. Now the problem of the LED placement coz the little black 'O' in the middle.

30 cm from the wall.On the floor to see the brightness at estimated 1100mA & 3.7V.
About 10ft away from the torch.
Direct at into the light. Wonder if it'll spoil the camera.
Still need regulator, else the heat can reshape the battery holder or even the battery EN-EL5 itself. Dangerous.
