This is completely OT but does anyone know of a source for 5 in., I think 4W UV tubes? I found a completely enclosed enclosure that has a regular 4W florescent tube in it. I was thinking of making a UV eraser out of it. Maynot be worth it since the ER2 is for $39 from digikey but if the tube is much cheaper then I'll go for that. Thanks, Shahid
