Thanks. I think koef3’s “corrected” test represents an emitter in a C8 reflector, but without driver and lens. If I understand koef3’s updates and follow-up post, the reflector alone seems to cost 6. If an AR lens costs another 6, that leaves around 8-18% lost in the wiring and driver.
The koef3 numbers I quote are the “reduced” values, which are labelled “CORRECTED” in the top-most “LED TEST” chart. The other charts only show the initial bare emitter figures. I am somewhat new to the details, but I do understand what domes do and such.
I’ve been reading this and related posts as well, but I was most interested in the difference between tm07 and nkresho’s lights. tm07’s light appears to be making 2000lm or more if both cd figures are accurate.
