I've got a Solarforce UV dropin (P60)
I can get a filter that will block about all of the visible light and let the UV through.
This is a 2" diameter round filter (that would be 50.8mm)
and I haven't been looking at flashlights with such big heads so have no clue what's available.
I see "SST-60" lights have reflectors/lenses around that size, but have no clue if this would take the dropin
Are there flashlights that will take a P60 dropin, and have a 2" reflector? Clue needed ....
<blockquote> Rosco's new Permacolor #3660 UV Pass Filter in front of a UV-rich source will do the trick perfectly. The formulation of the filter necessitates us to coat both sides of the glass, so this filter is more expensive that the other colors in the Permacolor range - but its dichroic formulation will hold up for many hours inside your newly created blacklight.</blockquote>

So I"m looking for a host that will take a P60 dropin, and a head that will host 2" diameter reflector and lens.
