Lumens of any flavor doesn't tell you the output characteristics (floody, throwy, or something in between).
ET publishes LED Lumen
and ANSI Lumen -
99.9% of the world does not know what ANSI means.
What percentage of car manufacturers publish Rear Wheel HP specs rather than Engine HP??? Same diff.
:shrug:
I personally prefer - and encourage manufacturers to publish:
- LED Lumen
- OTF or ANSI Lumen
and
- LUX
so that one can compare apple to apples between all the models and all the manufacturers.
- LED lumens is verifiable by looking at the specs from the LED manufacturer,
- LUX is verifiable with any cheap LUX meter.
- OTF/ANSI is not so easily verified.
I can't believe that in 2012, there is still some company that uses the intentially misleading and disingenuous practice of advertising emitter lumens to snare unsuspecting customers.
