Convoy S2+ with ZWB2 filter only way to go. I’m a little late to this thread, but for those still with questions about the filter you can get some answers here. For the fluorescent mineral hobby, a filter is a must. Other applications it may not seem so important, but a filtered light is significantly better than non-filtered.
On that note, has anyone seen the fellow selling Convoys with filter claiming that he owns a patent covering the use of glass filters in a UV flashlight. His claims are so broad, they seem to even cover any UV flashlight with any glass lens, even a clear one?

LOL, a discussion of the possible use of a Woods glass (link) and later the actual testing in a 365nm flashlight (link) here on BLF in 2015 was possibly the first ZWB2-filter/UVled-flashlight combination that was ever made (edit: nope, see pirateo’s post below), and was ultimately the reason that (much later) Convoy started building ZWB2 filters into their UV-lights. Further, in the mineral collection hobby, Wood’s glass and similar filters have been used in combination with mercury lamps for ages.
