Have you tried 1000bulbs.com?

They have a pretty wide array of bulbs.

Good luck!

I tried them, but they do not have any single contact bayonet base B15 bulbs - theirs are all pretty much standard domestic bulbs. I need something more exotic - bulbs that have a base that is standard in Britain (and other countries that use British bulbs), but at 120-130 volts. The only other countries I know of where this is standard (beside Saudi Arabia) are Barbatos and Jamaica, which use British sockets (because of the British influence), but use voltage around 110-120. Even Belize uses Edison screw base bulbs. The company in New Jersey sold them to people who had British or other foreign fixtures that they had not rewired. I guess there is not that much of a demand for this.

One of our clients goes to Barbatos fequently, but I don't think I could ask her to pick up some light bulbs for me. We have a showroom in London, but the light bulbs there are 220-240 volts instead of 120. I guess I could use those for the dielectric tests, but they wouldn't perform correctly.
