Hi Andy! Does your UV bulb look like a normal screw-base incandescent bulb? Or is it a long fluorescent tube? Incandescent UV bulbs work just like any other incandescent bulb. The only difference is that the dyed glass acts as a filter which passes UV light but blocks most of the visible light. All incandescent bulbs put out some UV light along with visible and infrared light. If you are comparing the filament of this bulb with a normal incandescent bulb, make sure both bulbs have the same wattage rating.
