I guess it would depend on which Spectroline flashlight you have.
I've only seen the Fluke RLD2 at a couple of trade shows, so I have no idea what the battery condition was, but from what I saw, my Sprectroline OPX-500CS OPTIMAX Jr light(the small one with 3 AA batteries) absolutely blows the doors off the Fluke one for UV light intensity. and range.
The fluke one can also be used as a flashlight, and has a laser pointer built in, but the UV LED's are fairly low output.
The intensity of the UV light put out by the single LED on the Spectroline light is orders of magnitude higher.
It is kind of like the difference between one of those cheep 20-40 lumen LED flashlights with a bunch of LEDs compared to a 100 lumen tactical flashlight with just 1 LED.
If more government is the answer, then it's a really stupid question.
