| Answer: Definitely more than one! I've had a high intensity desk lamp for a good 20 years, but this is the first time I've had to change the bulb -- a halogen 12V 20W JC G4 (two-prongs). I ordered replacement bulbs off the web, and have tried several, but the lamp still doesn't work. I'm wondering if it's the bulbs or the lamp (or even me). I do know to hold halogen bulb with paper, not fingers. When I insert the lightbulb into what seems to be the only spot possible (and from where I removed the burned out bulb), it feels as though I am pushing the prongs into styrofoam. Is that the way it should be? Photo of insertion area is attached. Thanks for any help to what sounds like a silly question -- even to me! |

| When the lamp failed to work, you assumed that the "bulb" (which actually is a lamp) had failed. And you have assumed that the "new" "bulbs" are good. Without testing by a knowledgeable person, it is not possible to know exactly what has failed in your situation. I have no reason to believe that you are installing the lamp incorrectly. |

| Failed transformer. |

| I do know that lamp is the technical term for bulb, but since I'm a lay person, I persist in using the wrong term. I guess my main question is whether inserting that type of lamp normally feels as though one is sticking the points into Styrofoam. It's the only such fixture I have that uses that type of lamp, so I've no comparison. Thanks. |

| Many bi-pins have little to no 'feel' as the pins insert, while some have a distinct 'grip' to the contacts. If you have access to a volt meter, a pair of small wire stubs will allow you to quickly see if there is any voltage at the socket. Be sure to check on both AC and DC scales. |

| Thanks, brickeyee. I don't have a volt meter, but we have a really nice old-fashioned hardware store in town -- maybe they will test it for me. Have a nice holiday, everyone! |
