Heinnie Haynes have some stats listed here: http://www.heinnie.com/Style-PS-&-Monarch-3-Combo/p--10670/Quote Monarch 3 -ANSI max luminous flux (lm): 16ANSI max beam distance (m): 18ANSI peak beam density: 81ANSI working time (h): 1816 lumen for 18 hours sounds pretty good to be honest, but I always take manufacturers numbers with a pinch of salt.

Light OutputTotal lumens of output, measured in an integrating sphere after the light has been on for 30-120 seconds. 30 seconds gives a little time for the LED to get hot and the battery voltage to sag which will usually result in a lower output number.RuntimeThe amount of continuous runtime (in minutes) until the light output drops to 10% of its original value (measured 30 seconds after turning the light on).This test is done using the batteries included with the flashlight.[1] If no batteries are included, the test is done using the manufacturer-recommended batteries.[1]The test is done in an integrating sphere just like the lumen test with light output measured every 15 minutes. 10% of brightness probably gives inflated runtime numbers. In the past, some testers used 50% to be a little more practical, but with most batteries, the drop-off is usually pretty quick and the time between 50% and 10% usually is not long.
