PR Bulb Focusing Spacers ?

[Bob96]

Many years back I had some thin washers that were designed to aid focusing in flashlights using PR Bulbs. The washer just slipped over the glass part. I think they may have been supplied by a Bulb Mfg.? Are these still available?

I seem to remember one of the incandescent "high performance" bulbs sold by Maglite came with small focusing washers. I'm sure these are still available, but I would check their website.

I have some bulbs that have the washers with them made by streamlight.... excaliber halogens is what the package says.
