Hi Pete, there are 2 different size battery sticks for these lights, both are a "stick" design, the LED model light uses a long thin stick batteries about the size of a "C" battery. the other light with the halogen bulb uses a shorter stubby battery stick, that looks more like a "D" size battery.
The LED battery stick part number is 20175, and the halogen bulb battery stick part number is 20170. Don't know if we have answered your question, the part numbers you sent us I don't recognize.
