*** Test Completed 9/9/2010; Results Below ***
Alright, I said I'd do this, so here it is... I'm going to watch the grass grow over the next few days and see what time will tell us.
Here's my test... At Noon today, I fired up 3 single AA Quarks and an Eiger #1 all running on AA batteries. (The Eiger via the VC AA Arc adapter)
2 of the Quarks (one XP-E and one XP-G) and the Eiger are running on freshly cycled (via the lacrosse discharge/refresh selection) Eneloops.
One of the Quarks (an XP-E) is running on a brand new Duracell Alkaline AA
I am having a heck of a time with uploading photos, so I'm going to run this test verbally for all of you as I'm simply running until lights off.
I'm not expecting much of a difference between the two crees overall, so I also feel the Alkaline running with the XP-E will be fairly indicative of the XP-G runtime when all is said and done.
I'll check the lights @ roughly 12 hour intervals and make updates here every 12-24 hours as I expect this to be a long one!!! (at least I hope so) I'll also update if anything changes... for instance, as the Eiger dims over time and gets to the output level of the Quarks.
Hope you enjoy this one folks, the latest of the lowest of the lows series of time killers!!!
Update 9/9/2010: For those of you intereted in the lithium primary version of this test, a new post has been started here: http://www.candlepowerforums.com/vb/...28#post3519028
Also, forgot to note that all three Eneloops came off the charger @ 1.46v and were between 1979 and 2000 mah as indicated by the lacrosse after the refresh
As for the three Quarks: One XP-E is a tactical, one is a standard. The XP-G is a tactical model. I Don't forsee this skewing anything, but if anyone knows differently, let me know
I honestly don't remeber which XP-E got the alkaline, but I'll note that at the end of the test. (It was the regular UI version)
Peak Eiger XP-G #1 (Eneloop AA, VC AA adapter)
25.5 hours to 50%
30.75 hours to less than Quark moon mode (The Eiger "moon" mode lasted 3.5 hours)
47 hours to tritium brightness and .97v
Conclusion: A very nice steady, predictable and utterly usable decline over the course of 47 hours. This light will not just turn off on you and the VC AA adapter is extremely well made and makes for a great camping/survival rig. (I still prefer the AAA format for EDC given its compactness)
Quark XP-G Tactical (Eneloop AA)
266 hours to off and .91v
Quark XP-E Tactical (Eneloop AA)
270 hours to off and .90v
Quark XP-E Regular (Duracell Alkaline AA)
470 hours to off and .77v
Conclusion: Holy Guacamole! 19.6 days continuous on an alkaline!
