For car camping
I have an old cantankerous Coleman dual mantle - if you don't prime and light it right, you WILL get a very good portrayal of Mt. Vesuvius. Impressive, but it makes the natives restless. Properly done, it does through a gawdawful lot of light. It has a soft spot in my heart. Though it may be from the heat and sun-like presence.
I have a wally-world kerosene lantern. Not nearly as much light, and no pyrotechnics. I drain the reservoir before packing, to ensure no spilling of fuel through where the wick comes through. It works, does the job, and kerosene or lamp oil is available in many places. Good kit.
I have a Coleman battery powered fluorescent lantern. It takes 8 D (yikes) or two of those large square batteries. It has two settings, kinda high and not so kinda high (can you tell there's not much difference?). For the weight, cost and output, I'm not impressed.
For packing:
I have one of the UCO candle lanterns. Neat little thing. Classy.
I had a Brunton LED Glorb, but have no idea where it got to. 250 hours on 4 AAs. Booyah. I miss it. Cylindrical, even light.
My in-laws just gave me a Coleman exponent LED lantern that i will be using at PWYP next month. It has a square shape, slides up out of a housing, takes 4 AAs and weighs half a pound. The square shape gives the light an interesting effect that I'm not totally sold on. It has two levels of light, but can be further attenuated by closing the light some (but not all the way, as it will extinguish the light). Coleman also makes a smaller, triangular version marketed more for backpackers. Jury is out.
I have used the candle in a pop-can. It worked for what I needed it for - light at the dinner table, but the candle wax did make a mess. Caught several bugs in the wax (take that bugs!).
I have used headlamps and flashlights as tent lights, including a Photon with a gator clip attachment that I think I lost. The Photon with a clip was pretty good - just a little light in an otherwise pitchy blacky kinda place goes a long way. With the clip, I was able to place it in a couple different spots. I have a Fenix L1D that I can't wait to see how it compares, with and without that goofy little diffuser.
I've also used cyalume sticks. Hate the green and yellow glow. They make white, but the white don't last as long.
Pros and COns:
White gas is versatile, if you also have a stove that uses it. Ditto for propane, so include that in your planning.
I do not know that comparative flammability of Kero to White Gas.
There is a caution about carbon monoxide, but most tents are ventilated enough for this to not be an issue - but think about it.
The candle in a can trick worked nicely, but I didn't set it up right and it wouldn't stay put in the wind. So I used it sitting on a table.
The UCO has Citronella candles (I have not tested these yet), 9 hour candles (they do last that long - verified on a trip to the Fingerlakes area of NY in the fall), and bees wax that cost more. I have not used the bees wax, but the advantage is that the higher the bees wax content, the less wax buildup you will have in the lantern. It can be a bit of a pain to pry, scrap and clean - but it's what you get. Alternatively, UCO also makes a tealight version and while I have not yet tried, I have heard you can rig a tealight into the larger lantern. Burn time is about 4 hours for most tealights.
Batteries - cold affects them negatively; lithium helps negates this, are lighter than alkalines, but cost more. NiMH can be nice, reserach the consumption curves in the product you're using it in. Additionally, if you are away and can standardize all your equipment to, say AA, then look at either a car adapter charger, or a solar charger for those longer trips. Costlier, but guilt free lumens has that nice warm fuzzy feeling.
I have simply typed and have only corrected typos as I saw them. There is no way I'm going to read my own drivel. Any mistakes you read are entirely your fault and is in no way attributable to me.
LOL - I've been reading Hitchhiker's Guide. Does it show?
