No problem ... but I should qualify that to say the Eagletac M2C4 is pretty close behind in overall output (when also run on 2x18650).selfbuilt,..hope you don't mind I trimmed your quote,
to highlight a very important statement.
Your statement holds alot of gravity from all your testing & comparisons.
Hard to say by how much - my lightbox and ceiling bounce show these two as roughly equivalent on 2x18650, but I know the wider spill and lower throw of the M2C4 is giving it an advantage in both these testing paradigms. Thrower lights (like the V2) are always slightly unreported by both methods.
