I have a lot of experience camping, and have used lots of lights in the tent for my family & me. Our current favorite & very versatile set up is a Quark X AA2 (now called the Quark QP2A-X) with a Fenix diffuser tip. It produces a true 280 lumens all the way down to a 0.3 lumens, and hangs from the center of the tent using a clip. The Fenix Diffuser Tip fits just fine, and spreads the light throughout the tent very well. When not in use inside the tent the light is one of the best all around general use 2 x AA lights. It has 5 output options plus 3 blinky modes. Here are the runtimes from Foursevens.com's website - Moonlight: 0.3 lumens, 15 days / Low: 2.7 lumens, 3 days / Medium: 24 lumens, 20 hrs / High: 115 lumens, 2.5 hrs / Maximum: 280 lumens, 0.8 hrs
I got the Fenix Diffuser Tip from FenixTactical.com. The tip is called "Transparent Diffusr Tip" for the LD/PD Fenix series of lights.
This whole set up is lightweight & great when you don't want to hike in with a monster sized lantern. I use rechargeable eneloops in ours for better runtimes compared to alkaline or I sometimes use Energizer Lithium batteries in it for the very best runtimes.
Another one of our favorites (but is a 3 D cell LED lantern) is a Rayovac Sportsman Extreme Lantern - got mine at Lowes. It's advertised as 300 lumens, but is more like 200 lumens. I don't take this hiking; just use it on basic camping trips. It has high & low. It can serve as a lantern on a table or, the hood comes off so it can hang upside down with its built in hook inside the tent (clever design.) It's a good one with awesome runtimes, and recommended quite a bit around here as a good LED Lantern.
Good Luck
