What do you have for lighting beyond a few hours? What about longer term-- 2 nights in blackout for instance?

One of my favorite lights: Quark AA², S2 Edition Medium: 19 lumens for 24 hours (50ma)

Hmmm, where to start.

A couple of D cell Maglights (LED converted - lots of runtime), Several LED lanterns (over 24 hrs each), way too many LED flashlights, 2 "normal" candle lanterns, a tea light candle lantern, lots of candles for candle lanterns, propane lantern with several propane canisters and mantles, more batteries, and then even more batteries.

And if for some reason all of that isn't enough I guess I could always start the generator.

The worst part of the above list is I am sure I left several light sources out.

Candles. 6" diameter pillar candles and 9-hour UCO candles -- several dozen of them. And several UCO candle lanterns to put them in.

Flashlight/headlight-wise: Petzl e+lites which supposedly have a 35-45 hour run time, depending on whether it's on high and low. I have a few of these because they're so small and great for having in a purse, pockets, car, trailer... They run on two CR2302 lithium batteries.

I also have some small e-Gear LED lanterns which allegedly run 48-144 hours on four AA batteries.

4 or 5 LED Lanterns.
1 rechargeable the rest run on batteries and last a long long time (days) before dead, and then when dead we have new batteries.

We have not had power for 5 days and used the lanterns and they work fine. We have used them through probably 10 more days of power outages and still as bright as first day

We don't only use them for occasional use too they are used for reading (with or without power) as well as low setting leaving lit to light up an entire room.

Original batteries still!

Next power outage.... next week by my estimate!

I go old school.

Can be used every night for two weeks without refilling.

Dietz Air Pilot and Little Wizard oil lamps for area lighting long term

LED lanterns for short term

couple of LED MagLight 2D and mini mag LED (with split rings to clip to belt.. part of the lessons learned 05 hurricane season)

cyalume light sticks

LED head lamps for movement

I retired the mantle type lights, but have a couple just in case

I do not think I have ever seen a need to run a light for a continuous 24 hours. My multiple battery operated lights and a slew of new batteries would easily go for a week or more if needed. After that my crank-operated Eton radio-light thingie would continue to work, though a pain. Candles, open flame fire, and I suppose at last resort my camp stoves could sort of work.

I am a fan of going to sleep when it is dark and working when it is not.

I assume you mean general room lighting. For that I'd use a 4Sevens MiNi AA tailstanding for ceiling bounce. (@40hrs. runtime on low). Or a Maratac AA/AAA, PALlight, etc. Most LED lights with a low setting would run for days, especially if used only at night. There's also 12hr. glow sticks. And lastly I'd go with candle lanterns due to safety concerns. For long term outtage I've got a small 700ma USB solar panel for charging Li-ion and NiMH and even a Dietz Air Pilot. But thats really for outside use.

Best Flashlight for indoor Blackouts I have found. It lasts 40 hours which seems like forever if you use it properly (Not leaving it on all day and night). It Floods with a soft not overpowering light instead of a focused bright beam great for keeping your eyes adjusted to candles. Takes three AAA Cells which are cheaper then AA's.

I also use an array of candles for all the rooms and my 3Dcell Maglite if I need to see outside a window or go outside.
