Oooo that makes perfect sense. Now I can finally read and understand selfbuilts charts when he reviews lights. Lol how about the different types of emitters and what character of beams it produces?
I know xp-g produces more concentrated beam thus more throw
While xm-l produces more of a floods beam.
Idk what xr-e is or q5 r2 r5 if that even relates to the latter.
Each emitter type has a 'bin' classification. The higher the bin the higher the lumen output for that emitter type. e.g.
XM-L's have been available in quite a few bins, the last three have been:
T6
U2
U3
with U3 producing the most lumens for a given current.
Q5 is a common bin acrosss several emitters (although means different things for different emitters), but is tyically meaning an XR-E. An R2 XR-E is a higher bin, but quite rare these days.
Things that affect throw are emitter luminesance (sp?). XR-E have a brighter surface area than an XM-L, it's just the XM-L is a lot bigger hence more lumens.
Reflector size, large reflectors will throw further than smaller ones for the same emitter.
Relative emitter size vs reflector. So a larger emitter in the same size reflector will throw less than a smaller one.
Lumens do play a part of it, but a bit like torque does with engines when talking HP. In the way that more lumens might mean more lux, but they might not depending on other factors. However given equal variables a higher lumen emitter of the same type will throw further if all else is equal.
