Pretty dumb rewiring question

I have what I think is a really basic rewiring question that I hope someone who knows more than me can help me out with.

My sister bought me a beautiful lamp in the UK that I have coverted for a while, but the problem is that I live in the US. (Read - I can't just buy this in the US and save myself the hassle!)

The actual bulbs are like Christmas tree light type affairs rather than regular incandescent bulbs. The fixture plugs into a transformer (the plug from the fixture is tiny and I don't recognize it as any standard). Transformer input is 240v - 50hz and output is 24v - max 50 VA.

Now, I assume that I need to use a different transformer, but I don't think its just a simple job of buying a new transformer (and US plug), plugging it in to the fixture, since the aforementioned output plug is very odd. It is 2 pronged and roughly 1/4 inch diameter.

Can I just rewire the fixture thus:-

1.cut off the weird plug from the fixture
2.Get a new transformer (pressumably input 110v, output the same - I'm guessing a standard for Christmas tree lights)

splice it in
away we go

Am I missing something? If this is correct, are the parts I would need expensive?

Many thanks

You might want to consider changing the bulb type to 12 volts. 24 volts is not standard here. Juno makes a transformer for that but the cheapest is $180. I'm sure you could find a surplus one for a lot cheaper. Are the sockets something that's compatable with American bulbs? BTW when I do this kind of rewiring I stagger, solder and use shrink tubing.

Can also be expressed as *pints halogen*.

You seem to have the right idea, most transformer packs seem to come with an output cable so just splice that onto the lead from the lamp. Stagger the joints a little and solder and tape.

If you havetrouble finding a transformer, then search the Newark site - or maybe Digikey. They supply transformers of all varieties, and are sure to have one suitable. Best to show it to someone with a bit of electronic knowledge to make sure it's suitable. The cost in the UK would be around £15 ($25?). Could always post to sci.electronic.basics ... hth Neil

sounds like a quarts halogen lamp.

dunno about christmas tree lights, but the transformer shouldn't be too hard to locate. try a lighting supplier.

If the transformer is bare a case would be a good idea.

I'm guessing $40

You might have a browse at the local tip for a printer power pack of the right voltage - might save you a lot of work
