Robin,
Fly Zapper tubes are around 350nm but will be changing soon to 368nm
The following from:
http://www.lamps-on-line.com/uv-lightbulbs/blacklight-bl350.htmlApplication:
The most popular application for BL350 bulbs is in Bug Zappers or Fly Killers.
They can also be used for Nail Curing, photopolymerisation and curing of plastics and varnishes.
Technical:
bulbs emit UV Radiation at 350nm.
Recent changes to legislation (RoHS compliance) has meant that
lamps in the near future will emit UV radiation at 368nm.
Although called Black Light BL350 bulbs are white in appearance and have the same electrical characteristics as standard fluorescent tubes.
