Rayovac Extreme 300 Lantern - replacing the LED (Mod)

[BigRiz]

The board you see on CNC is called an MCPCB for Metal Core Printed Circuit Board, and it is required, so if you buy the LED by itself, you would still need to solder it to an MCPCB yourself, which requires reflow soldering, and is very difficult to do at home.. so definitely, always buy an LED that has already been soldered unless you're really get into the game and get the required equipment.
