I have been debating between getting Streamlight's Stinger HP led, Poly LED, and regular Stinger for use in out Detective Bureau (I of course have my own lights
). I have an HP I recently purchased and must say, it is a thrower and can really reach out and touch someone. I am, however, giving it to my dad for use in spotting animals at long range on his ranch... The beam is just too tight (can something be too well focused:shrug:?) and it doesn't give enough spill for our uses. So I called out local Streamlight rep to ask about beams and reflectors, and why the three models all have different lumen ratings, as there is no explanation on the factsheets. I knew one had an OP reflector, but wasn't sure which one.
First, they advised all three lihgts have the same LED and driver (explains the similar runtime graphs). She said the lumen difference (140 for stinger, 180 for poly and 200 for HP) was because of the reflector difference. Now, I thought the Lux (throw) was the result of the reflector, and Lumens rating was total light from the LED itself. Is this misleading? Shouldn't all three have the same brightness, just focused differently? The regular stinger seems to have the beam we want, but 140-200 is a pretty significant total brightness difference (25%). Are they measuring this different than others? Also, they do not give Lux figures, but candella (which I know is also a unit of throw). As expected, the candella increases with the lumens. Do OTF lumen ratings change with the reflector? Could this be the lumen difference?
I guess my overall question is: Is Streamlight advertising their lumens differently than others and are these figures misleading, as compared to other manufacturers?
