Substitute for a G2.5 lamp?

For Christmas, I got a light that uses a G2.5 lamp. I didn't know "G" lamps also come in pin-size 2.5.
It looks like this:



I want to use hi-cap NiMH's and a lamp with a high amp rating in this light. The G2.5 seems to be practically impossible to find (where I live anyway) and I don't know if it's available in hi-amp either, so I'm looking for a substitute.

Anyone have any ideas?

I might also experiment with overdriving a three-cell lamp (like the Tec 40 trick), but that would be more for fun.

Thanks for any help you can give me.

The 4.8 mm bulb envelope circumference is the same as exists with T-1 1/2 bulbs.

Welch Allyn's T-1 1/2 bulbs have 3.05 mm pin centers with .203 diameter pins.

Carley's T-1 1/2 bulbs have 1.270 mm pin centers with .508 diameter pins.

The wide G2.5 pin spacing makes it non-interchangeable with the alternatives that first come to mind.

Don't really understand why my post has been moved here, as all I want to do is change the lamp. I see such posts on the general forum almost every day. Oh well.

So Lemlux, you don't know of a direct replacement? Perhaps a stupid question, but what if I carefully bend the pins of a possible substitute?
