I picked one of those PL-20's a while back in someones basement and it works fine with your typical Mag or Streamlight 6V NiCad recaargeable. i believe the replacement bulb is the old school Streamlight SL-15 (remember those). You can also drop 4 C alkaline's or rechargable C's and it works fine also if its the aluminum model with a slight tail cap spring modification. But if its the ABS plastic C's wont work because the spring wont allow you to screw the tail cap back on and you dont want to modify the spring or change it due to the need for the spring to ground against the thin metal strip along the inner wall of the light body.
