I would highly recommend the Survival PALight with the 5mm LED & the white cone. Get the Motorist Pac & request the 5mm LED & white cone. In the tent you'll have a very low, medium, & bright area light. The always on is great because it'll let you see around the tent but not bother your sleep. There are now 2 different ways to hang it: a wire loop on the end & the SS clip on the side. You'll have to take out the lens to put in the cone, but that's the way I prefer to use it anyway. If you need to go outside for something, just pop off the cone & turn it on high. You'll have a light that puts out a large area of light with a decent centerspot. Also, if you go walking at night, you can put the cone on, hang it on the outside of the tent, & put it on flash. Makes it very easy to find your site when you come back (and your not having to shine your light on everyones tent, if you camp at a site with other campers).
The Energizer folding LED Saaby mentions is nice too, but even the 1 led mode is too bright when you want to sleep. And it doesn't convert to a flashlight. You'll also probably find the PALight pulling double duty sitting on your nightstand when you're not camping. I think the PAL is the perfect tent/bedside light. TX
