What is a good source of light that doesn't use electricity and won't use all my oxygen?

I am looking for a way to provide light in my room without using electricity. I tried regular candles, but the flames ate up all the oxygen in the room within a single hour. It is far too cold for me to open a window, so that option was out.

The light doesn't have to be overly bright, just enough to read by. It need not be on twenty-four hours a day - more like ten or so hours per week at most, perhaps for five hours at a time. I'm not ruling out fire, but if I'm going to use fire it will have to be in such a way that it doesn't consume very large amounts of oxygen too quickly. I cannot drill holes or modify the building in any way.

I am hoping that perhaps there is a particular type of candle or burning fuel that prevents the fire from using too much oxygen. Any and all ideas are welcome, I only hope I'll find something that works.

Update:

I'd prefer not to spend too much money, as well. I worry that buying tons of glow sticks might get expensive over time - the idea is to save money on electricity.

Update 2:

I'm trying to avoid battery-powered items as well, as batteries become very expensive over time. Rechargable ones lose their charge too quickly, and regular ones are just plain expensive, especially the lithium ones which work the longest.

The flashlights that you shake to recharge do not produce enough light - I've tried them.

I'd also like to stay away from electricity completely, including things like batteries, if possible. I'll use it if it's my only option during the winter when it's too cold to allow air into the room, but I'd prefer not to. The room is very small, and I had to light about ten small candles to get the amount of light I needed, so it did use up O2 very quickly.

    Chemiluminescence (a/k/a firefly light) would work, but it's expensive. The commercial version is a lightstick, usually used in emegencies or for directing traffic at night, etc.

    If you mean only that you don't want to use electricity from the utility company, you can use a crank or galvanic flashlight that charges a battery by shaking or cranking. Usually these have LED bulbs because they use very little power per lumen (light output).

    All burning uses oxygen, though it's hard to imagine a candel using up too much oxygen in a room. A gasoline or propane/butane lantern (like a Coleman lantern) is very efficient in its use of fuel (and hence oxygen) because it uses the generated heat to cause rare metals to glow. This is might brighter than just the light from the burning fuel because some of the heat energy from burning is converted to additional light energy. Do, however, be careful using any combustible fuel, especially gasoline, indoors. And don't use it in a small enclosed space (like a tent) where you could use up oxygen faster than it's replaced.
