My bi-pin to PR holder Mod

AW · Aug 13, 2005

Spent couple hours fooling around with some left over ceramic materials.......

Made a few of these ceramic bi-pin to PR base bulb holders. However, the bulb filament is riding too high for a proper focus, I have to adjust the socket by inserting a spacer to lower it by about 5mm. I put in a WA1185 and ran through a whole set of batteries for about 45 minutes. Nothing melts and everything seems to hold up pretty well /ubbthreads/images/graemlins/blush.gif

I tried that a while back, but over time the ceramic in the holes got eroded away and the bulb would not stay put. Kinda annoying....

It is the metal pin holders inside holding the bulb, not the ceramic itself. My pin holders have a very tight grip holding the bulb.

Willie Hunt supplied me some holders like this several years ago. I don't think he made them. Just this week I was wondering if I could get more or whether to have a go at making them. Your post may have tipped my balance towards making some.

I use them in bicycle headlights with a 5V 0.85A bi-pin xenon halide bulb. Any ideas of good sources for these or similar would be appreciated - I can't find them in Australia! Don't want to go much over that because the Audax riding I do requires very long run times.
