If you are still sourcing UV bulbs, you can buy BL (Black Light - the type used in pubs and clubs) tubes and bulbs from branches of Maplin Electronics - website is at http://www.maplin.co.uk/ . Look under 'disco lighting'.
BTW I expect you already know but it's best not to look into the solaria without eye protection for any length of time.
Thanks; are Ray Bans sufficient to check the print exposure ? Otherwise, what do you use ?
Thanks for all the input guys, I hope it helps others going into alternative printing too, because most of the "vocal" people and articles speaks of experienced users who "build their own" etc.
Might all be very well to make one, but that doesn't help newbies getting started :-)
