I use a rechargeable Nitecore LR10 for my tent lantern. 2 oz and its very nice to have at night. Outside the tent its all up to my headlamp and either the moon or the campfire.
Solar powered Luci lights work great, lightweight, no batteries. I hung 2 in the sleep tent and 1 in the cook tent this year and it worked well. Just put them outside in the a.m. to charge all day. If we needed more light in the tent to dig through a bag we used headlamps. Very pleased with this setup.
