Query: how many people to change lightbulb

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.
It could be either.

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!
