    Lightbulb Non-Blue Light Emitting Sources?

    I'm quite keen on cutting blue light out of my evenings when the situation allows, but I've been having trouble. My primary pre-bedtime habit is reading by candlelight, and I have a terrible qualm with it.

    I use some tea lights I got from my local perfumery, which are, unfortunately, unreliable. When you first light them the flame is so dim I have to light lots and lots, as the flame doesn't really get illuminating until the wick has burned a few minutes, melted the wax slightly, and had the wax harden again.

    I sleep on the floor atop a sleeping bag -- in it, in winter; I'm in Texas -- and place some on both sides of me to ensure total lighting. In the best of times I only need two, but when the candles aren't burning in my favor I can use up to six at once, and they go fast.

    I have plenty to keep me going for now, but once I run out I want a better, more reliable alternative. Are there, perhaps, flame sources out there better suited to light up the place, or perhaps a non-blue light emitting electronic.

    I do have and have used orange-tinted glasses, but I don't like that the light can still seep in around the borders and the way my color perception is so drastically changed. I also have F.lux on my computer, but that's largely irrelevant.

    Thoughts?

    I love oil lamps, especially the ones that are adjustable and have chimneys. They do burn liquid paraffin (i.e. a form of kerosene), so they emit some toxins (carbon monoxide). But, then, so do paraffin candles (which most candles are unless they state they are beeswax or soy, etc.). Oil lamps do tend to burn clean, especially if you don't have the wick up so high it smokes, and if you're using ulta-pure lamp oil. And, they do a great job of emitting light. You just have to weigh the pros and cons for yourself...

    If you are new to the PB - please ignore ALL of this stuff, until you've read the book, or at least http://www.marksdailyapple.com/primal-blueprint-101/ and this (personal fave): http://www.archevore.com/get-started/

    Thanks all. Interesting advice.

    Sounds good, but only partially. I sleep on the floor, which is carpeted, so that sounds awfully dangerous unless I were to take some steps to fireproof the area, which I might be able to if I expend some thought. I may not get it for my bedtime reading, but it sounds practical for putting on my stand-up desk for nighttime studying/writing. Thanks!

    What I really wonder if, aside from the oil lamps mentioned above, there's a candle with a special type of wick out there that will burn more brightly due to its construction. After all, old timers of the past once had to write by candle-light, no? Perhaps since the candle industry was much bigger back then they had developed a more practical way for them to be made for lighting? Our current society doesn't value candles for their lighting purposes much anymore, which could have change their construction due to the change in purpose. My tea lights, for instance, are more meant for mood lighting and scent distribution, not illumination.

    For now I'll consider saving up for an oil lamp and continue on investigating.

    To some extent ... I expect most people got their heads down. And a few followed other pursuits that are perennially popular and don't need much light, such as drinking.

    I've got a copy of At Day's Close, which is a fascinating history of nighttime. It tells how some people liked to get up during the night, after sleeping for awhile, and do this or that before returning to bed. We know this from personal letters and so forth. Certainly some people wrote:

    Amazon.com: At Day's Close: Night in Times Past (9780393329018): A. Roger Ekirch: Books

    I guess the amount of light you gets depends on how many candles you burn. And, then again, they may have had a fire going, too.

    Poor people may have used rushlights rather than candles on grounds of cost. However, I recall that indefatigable diarist Gilbert White writing that his poorer parishioners would often buy candles rather than use rushlights, although people of middling income like White himself were sometimes reluctant to do so.

    I think people did what they wanted, or could, depending on their habits, the price of lighting and so on. Or you might be in a situation where you had to pay for lighting materials so that you could pursue a trade after the hours of darkness. People would sit up over their work after dark, women over sewing, for example, if they needed the income from that.

    ________________

    You might try pure beeswax candles. They burn cleaner than candles made from tallow, leaving no residue and no unpleasant smell. They might possibly be a bit brighter, although I've never thought to compare that. I guess yellow or red colored bulbs in tablelamps are more practical, if less atmospheric.

    The low-energy bulbs give off predominantly blue light hence I am against them.

    I use very low lighting during the evening and am a fan of candlelight.

    There are 12v LED lights out there that emit little blue light. Some are even dimmable. Initially expensive but they have a long life

    I got an oil lamp and LOVE it. It's the perfect solution. Very, very bright for any reading and writing, without any worries as to it petering out too soon or being unable to burn sufficiently. I might get another one for "stereo" light, though it's probably unnecessary. I think this is all I need.

    I have heard before that blue light in the evening can wake you up and make you more lively
    Our bodies have developed to produce serotonin in the daytime and melatonin in the nighttime. Serotonin, among other things, makes us wakeful while melatonin makes us tired. One huge thing that influences serotonin secretion is the blue portion of the light spectrum -- blue light.

    That means that if you expose yourself to blue light sources at night, such as from your computer, you can trick your body into thinking it's daytime and secrete serotonin, which can drastically hurt your sleep.

    Hence, I've been looking for better lighting sources for my night reading. Flames, I've heard, don't emit blue light at *all*, which is why I've been going to candles and oil lamps. I can read however much I want in the flame light and still get a great night's rest.

    Oil lamps can be pretty inexpensive. Fred Myer and some home improvement stores sell them for (if I recall correctly), about $15-30, and the oil is about $8. As long as you don't knock them over, they won't be dangerous...

    Amazon also has oil lamps. I have quite a few from Lamplight Farms, and they work very well and are very affordable. They're the same ones you can find at Fred Myer and home improvement stores. I like--and own--this model with the loop to put your finger through to carry it securely:
    Amazon.com: Lamplight 110 Chamber Lamp: Home & Kitchen

    Here's 32 oz of lamp oil--it will last many good hours (about 60 hours):Amazon.com: LAMPLIGHT FARMS 6045 "ULTRA-PURE" LAMP OIL 32OZ-CLEAR: Home Improvement They also carry it in the 64 oz size: Amazon.com: Lamplight Farms "Ultra-pure" Lamp Oil 64 oz Clear: Home & Kitchen

    I hope that helps!
