chaos is probably referring to Quark 123², S2 Edition:
Quote:
Moonlight: 0.9 lumens for 702 hours, (1ma)
Low: 4 lumens for 120 hours (10ma)
Medium: 19 lumens for 20 hours (50ma)
High: 83 lumens for 270 minutes (250ma)...

How long will the game last?

I have the AA version and it's a great light. Numbers are a tad better than the 123²:
Quote:
Moonlight: 0.2 OTF lumens for 30 days (1ma)
Low: 4 OTF lumens for 5 days (10ma)
Medium: 22 OTF lumens for 24 hours (50ma)
High: 85 OTF lumens for 5 hours (250ma)...

If your life depends on a specific tool, don't worry about the cost effectiveness of throwing away an extra $50 . . . In the real world, you can carry extra batteries. I use AA lithiums in that light.
