If you have an XML and xml2 in two identical reflectors, and both had 800 lumens would the throw be the same?
If you don’t mod it, (and for arguments sake assume that my previous calculations were correct) and decrease the output from 3000 lumebs to say 1000 lumens, then the kcd would just be 45kcd… Right?
My entire reasoning is based on that premise. I will measure this next week to confirm, unless someone else volunteers (its a 2 min experiment).
My two personal examples of the XM-L2’s offering a higher percentage of Kcd vs lumens -
TN31 XML U2 - 1075 otf at 30sec
122Kcd
TN31 XM-L2 U2 - 1275 otf at 30sec (18.6% increase in lumens)
157Kcd (28.6% increase in throw)
BTU XMl U2 - 2975 otf at 30sec
132Kcd
BTU XM-L2 U2 - 3670 otf at 30sec (23.3% increase in lumens)
181Kcd (37.1% increase in throw)
All these were done with the same batteries and same meter before and after testing. Not sure why, but XM-L2’s to appear do be better throwers than XML’s.
I was showing mine off all week. My son and daughters friends were amazed. It’s like turning on a streetlight in your backyard. Any light that smokes my TN31’s to me is pretty damn mean. This BTU is mean.
