FW3A Useful Information.....

Not that simple. :slight_smile:

There is a ‘shelf’ between the driver and LED MCPCB. This light is not a ‘pill’ design.

Remove bezel, lens, and optic from head.

Unsolder red and black wires from LED MCPCB.


If you are swapping just the LEDs, you can leave the driver in place. Otherwise, remove driver ring and remove driver.

Clean the old thermal compound from the shelf and the MCPCB. Use a small amount of new thermal compound.

Be careful not to twist the red and black wires when reinstalling the optic/lens/bezel.
