Yeah and then do what I did...find some pics here
Energizer Folding LED
Basically I took 2 old hard drive magnets, and added a magnet to one of them. I know that sounds crazy but the magnets aern't magnetized throughout the metal, no a 3 magnet approach was necessary. The black magnet is cemented to the HD magnet. Then I cemented a mounting plate (Like $0.58 for 10 at Lowes) to the Energizer and then you stick the single magnet outside the tent and stick the double magnet inside the tent and then you can easily "stick up" and "pull down" the LED Lantern. It was almost perfect for a Springbar tent, just a tiny itty bitty more light would've been nice, but springbars are really tall tents, so for your application it should be fine.
The Arc AAA is only found on the Web. Texas Tactical Supply and, if they have them in, Vicomtel are the best plavces to get it. Having an Arc is an absolute must. Get one. You'll be glad, but I think an Arc is almost but just not quite enough light for a 6-man tent. Smaller tent? Sure, 6-man...not so sure.
I think the thing I like the most about the Energizer is that because it isn't a torch it's more useful than you'd expect when camping. Somethimes it's nice to have a highly defused light, like for outhouses and stuff.
Now to answer your question, what's the
best light for a tent...that would be the superlight I'm working on
