Well, point is, if you know how to wire a fluorescent lamp, you have the circuit. If you want a timer, then catalog no. Z60072 in Vorlac's ( http://www.vorlac.com.au/vorlac/vorlac1.htm ) December/ January clearance stock for 50¢ should do the job nicely (you supply the knob!). Supplier of germicidal tubes *used* to be Gelman Clemco/ Gelman Sciences, but hey, that was long ago and far away. If you buy a 4W tube and get a small fluorescent lantern from FDBs/ Woolworths, could be quite cheap. If however, a 20W tube is just as cheap, consider a 20W fluorescent batten fitting, approx. $20. Look for some painted (black) metal louvre mesh to make a skirt all around to keep the UV in but air circulating and fit an interlock switch in the bottom so it only operates when standing on the bench (on a piece of newspaper - don't stand it on the carpet!). Of course, I scored one at a garage sale (but it was from a mate). -- Cheers, Paul B.
