More tubes
Thanks richie boy i forgot to mention this is a T5 tube. Can this type be powered without ballast and starter?
I've attached a new shcematic with 2 tubes is it correct? In case yes can i keep adding my other remaining 2 tubes in parallel as shown? This would mean 4 tubes in parallel 1 stater and a 30W ballast.
Thanks

I use proper UV tubes designed for PCB exposure, I got them from RS Components a few years ago. I usually expose for 3 minutes. However your tubes will probably be a different wavelength as well as having different power and coverage so you need to experiment with the time.
Hi richieboy do you have a copy of the plans you have used with dimensions you can send to me if possible. My email is thrillseeker182@yahoo.com

BIG Problems with my Tubes
Am back after some long time. I tried to experiment with my tubes in parallel or series as attached but was able to keep only 1 tube on. In the attached wiring its always tube 2 which gets on. From time to time 1 can get tube 1 but for only a few seconds but then tube 2 switches on and tube 1 is off. Could it be the ballast or something else?
If i connect only one tube it works fine but for two only 1 is on.
Thanks for the help

Thanks again richie boy but the thing that strikes me is how it is behaving so strangely as only 1 tube is on. By the way these tubes come from an insect killer they sell at Game store here. I've lighted one of the units but its really light. I wonder if these actually use a ballast inside????? Its not worthwhile buying one to dismantle it. In case i can i'll try another ballast just to check. At worst the only choice is 4 starters, 4 ballast
