I am not familiar with the light used to test Euro bills. I suspect it is UVA (400 to 320 nm). In discussing UV, I prefer to refer to the wavelength, as that is not ambiguous. The manufacturer of your photoresist will tell you what wavelength is needed. It will probably be something around 366 nm +/-10 nm. However, some emulsions react to visible light.
Wikipedia gives the definitions of UVA, UVB, and UVC. Since you will be using regular glass, not quartz to press the positive image and sensitized plate together, you can be vitually certain your plates need UVA for exposure.
As for which bulb is best, check the label on the bulb. One clue is the appearance of the "glass." If it is perfectly clear, it may very well be a germicidal lamp with a quartz or quartz-like (Vicor) envelope. They emit mostly at 254 nm and are no good for making PCB exposures. For one thing, none of that wavelength light will get through the plate glass pressure plates.
If the tube looks white when it is off, if is probably a UVA bulb with a white phosphor. In the USA, it is type BL.
Different emulsions seem to be more or less sensitive to the light. MG's plates seem quite sensitive, based on reports I have read. I use Injectorall, and 3X15W new UVA bulbs at <6 inches take about 10 minutes. You can roughly judge your exposure time by the wattage, but it is not a precise calculation, and distance from the plates makes a difference too.
Good luck.
