Dividing battery capacity by tailcap current is a good reality check, and it’s a lot faster than a runtime test.
Determining candela is easy with a lux meter, and relatively few lights have this specified, but an amateur’s at-home measurement of output in lumens has even more variables than a runtime test, making it less credible to me. Even though few believe manufacturer’s lumen claims, we crave hard numbers :bigsmile: , so we get amateur lumens measurements. A reality check would be to compare measured emitter current with an output graph from Match . I don’t know how accurate Match’s lumen numbers are, but at least there would be a common reference point.
Heh! I think we already have one. :Sp
