I actually just purchased the 502b AND a 9 uv led and they both aren't very useful for detecting fake IDs and cash... I spent about $15 for just the 502b bulb and it's wavelength is 390-400. Try shining it on an ID with uv markings, it'll still light up the markings, just not very well. The "Urine off" UV led tends to light up every uv hidden item on the IDs as well as cash. Most of the WF501B's light is white light because it's at the end of the wavelength spectrum. Bright doesn't equal useful.
