Check out LED lanterns. They are really bright (with a white light, but whatever) and the LED lanterns I've seen (~$20) will burn for something like 300 hours on one set of 4 D batteries. No rechargeables needed.
As far as Tiki's go: they are okay, I have just never wanted to deal with their leaking. Classic scene this September at Redwall Cavern: TL from another trip says to me (TL),
"Hey, are you guys leaking something?"
I say, "Uh, maybe, why?"
"Well, my wife said she saw some oil or something washing up on the beach over there." He says with a gesture over his shoulder.
"Oh, that's just XXXX, he was washing out his Tiki Rocket Box. No biggie, we'll try to keep it down. Hey, do you want a hit?", I say.
"No thanks. Where are you guys camping tonight?" he says.
Pretty classic Grand Canyon conversation.
