Those spex are only valid when the light’s sitting still. Once you start moving the light around, it goes into higher-current mode and runtime drops to 34.5hrs, but it’s lots brighter!
I think he means that moving the light around would allow for better cooling - the assumption would then be - that thermal regulation would affect the outcome.
Nobody remembers the Volkswagen “scandal”? The car runs in “clean” mode when on a treadmill and not moving (ie, it knows it’s being tested), but in Real Life™ it just runs nicer.
It was a joke. Like the funny kind, only different.
Oh, I’m sorry but english is not my first or second language . I do remember the Volkswagen incident, now I get it . I thought the flashlight had some kind of integrated motion sensor like there was or there is a maglite. I have always thought that motion sensors should be integrated into the flashlights for several purposes:
- If you have an accident in the mountain (or other distant place) and the flashlight know that is not moving then it would change to a beacon mode and very low consumption.
- If you forget to turn off a flashlight, she alone would go into saving mode.
- If an elderly person falls, the flashlight could switch to an alert mode or call for help.
You can turn on or turn off a flashlight by shaking it, baby!
There are many applications that I can think off, and with tiny accelerometers is even more easy for manufacturers or even hobbyist to integrated it in the drivers. But somehow motion sensors are not a “thing” in the flashlight world.
Per request, here is a dump of five other runtime graphs from five of my other Maglites. Note that these were done over the last two years, and the format is not always the same. Some of the graph's notes were meant for my own knowledge, and not necessarily for posting (keep that in mind). Some of the graph's lumens values are based on Maglite's spec, some are based on the Texas Ace Calibrated Lumens Tube. None-the-less, this is a great snapshot of how Maglite handles runtimes. One of Maglite's tricks that you'll see on some of their lights - is to have this initial spike at 40 sec (not 30 sec per ANSI) right after turn-on that only lasts a few seconds, which then becomes their basis for lumens output on high.
The first is my foliage green ML50LX, a 2C LED light (HIGH).
Yeah, I think there is a Mag that does that, an XL something? 500?
I could use that for mum. She leaves flashlights turned on overnight, etc., and claims she doesn’t. Crappy 3×AAA lights, but still. I burn down those “dead” cells in dumb lights that wring ’em dry, and I can’t even keep up, not even “wasting” them as nightlights.
Something that’d turn off the light after 5min of non-use would be ideal.
Thank you so much for this. So, they are cheating about the high mode, but no the low mode.
Still a lie, but at least they have the expected performance in low mode, sometimes is what you are looking for in a flashlight, low lumens but very long runtime.
This thread is primarily about the 6D version of this light. However, having just purchased the 4D version of this light, I'll post the runtime graphs here, rather than making a separate thread.
The 4D version of this light is fairly new. Maglite makes an interesting claim (here) on the 4D version, which would imply that you'll get 1000 lumens continuously.I have not seen this type of claim on their other lights. From Maglite add (snip):
The runtime graphs will tell us if the above is true . . . .
We'll start with 4 NiMH Powerex D cells. Note the common characteristic I've seen with other Maglites when first turned on. The output ramps up to peak brightness during the first minute, before throttling way down. Note also, I could not get the claimed 1000 lumens with the Texas Ace Calibrated Lumens Tube (although we're within 10%).
Here's the same graph zoomed in to the first 15 minutes:
The 2nd test is with 4 Duracell Quantum D cells. Note Maglite uses alkalines on their runtime tests. Note again, the initial ramp-up to peak value in the first minute.
Here's the same graph zoomed in on the first hour:
