Nice review. Question - you say it maintains 2000 lumens for almost 2 hours but neither runtime test supports this. Just wondering how you come up with that?
“Excellent Runtime, it manages to maintain 2000 constant lumens for over an hour”
“• Turbo mode starts with 4000 lumens going to about 3200 lumens in 10 seconds. This level manages to remain almost constant for 3 minutes until the temperature rises dramatically and the torch is forced to step down to a lower level of about 2000 lumens. After 6 minutes there is a stepdown to an even lower level of about 1000 lumens and from here on the brightness remains constant for over an hour and 20 minutes, up to the direct drive of the vials and turning off the flashlight.
• The High level starts with an output of about 1800 lumens and then goes, after two minutes, to 1650 lumens and after another 20 minutes to 1000 lumens. From here on it behaves exactly like the Turbo: constant light for over 1 hour and 20 minutes until direct drive.
• The Medium, Low and Firefly levels show a constant trend for the whole duration of the tests. A sign of excellent regulation.”
