I can’t tell from your pics of the pill, but your pill appears to be similar to the dive light I reviewed previously, here:
In this case, the driver is press-fit into the pill and should be removable. Mine had a single screw under the driver which held the pill/PCB/reflector assembly together.
My suggestion would be to retain the existing driver, and replace the existing LB clone emitters with something better.
Based on my picture of the driver, it MAY be resistor moddable…
…if you lower the resistance of the two parallel R150 resistors… I haven’t tried this on mine; it might burn the driver or not work as expected, but it’s a thought.
