Help with Solarforce L1200

Before I wreck-it-ralph what appears to be a hard item to find now (the driver) it appears the legs to the current stock bulb are soldered to the G4 socket. Has anyone had any issues removing the stock bulb and using other bulbs…does one need to RE-solder a new bulb in or is it good to go? The current bulb I have now is stock and working but I want to change it out for a 12v 35w Jc bulb.
