    Default LEDs can have a negative effect on your health and eyesight.

    http://tapnewswire.com/2016/10/to-pr...escent-lights/ --I came upon this website while doing a search and felt like I needed to share it with y'all. The article says that the red in sunlight, candles and incandescent lighting is good for you and healing. The warm white LEDs may appear warm, but still aren't close to incandescent lighting. If you have to use LEDs, use ones with the highest CRI (97). Also, the flickering (pwm?) of LEDs is also bad for you. Good news though, in another article on another website from December of last year our president deregulated the legislation that was going to kill off incandescent lighting. Bad news from another website says he's being sued for doing that. If our president wins this we can at least have access to healthy lighting again. Don't get me wrong, I find LEDs very handy, useful and efficient, but after reading the article I posted, I might start ordering some incan bulbs.

    Yes, this has been known for a while now, we are programmed for, sunlight, fire, candles, oil/other fuel lamps, incandescent bulbs for reasons mentioned in the article.
    I think LED's are convenient for many reasons except your health.
    We now walk at night in our local large forested reserve. My wife used to carry a small LED light but since trying out a variety of my incan flashlights, she prefers them even though they are larger and heavier.
    Having said all this.....when we will get our next camper trailer, we will insist on installing only warm white LED's in it, yes in this case the convenience factor wins for various reasons....our flashlights will remain incan....

    I found some halogen bulbs for a table lamp recently. Made in USA too.

    For flashlights I really like Tung Sol bulbs. Nice beam, nice sunset glow. They were produced before krypton and xenon entered the scene. Maglite bulbs are the most durable for PR based lights but those Tung Sol and Chicago Miniatures (from the 1960's) just put out a nice color.

    I ordered some bulbs for my solitaire and today I checked my email and Tony Maglica has written me a personalized thank you message because I bought something from them. - Now that is a nice touch indeed. Never got that from Walmart, white's or home depot when I bought a maglite. I invited them to come on the forum since fenix is already on here and there are a lot of people here that like maglites.

    My android is the main source of blue light, so last night I installed a blue light filter from google play and also a pulsating red light app that is supposed to be a healthy thing to look at--don't know about the latter, but I got sleepy as soon as I started using the blue light filter and it wasn't too long I done went to bed. Maybe that is why I stayed up all night long and got sleepy when I saw the sun. The sun was giving me what I needed to go to sleep compared to my android robbing me of it. Now I understand--I thought I was just weird or something.

    Mr. Bykfixer, a dorcy 4.2 volt krypton bulb in a old 4aa flashlight of mine puts out a beautiful beam of light. It is the original bulb that came with the flashlight too. It seems to have a warmer color temp to it than rayovac or maglite bulbs--krypton or xenon. I like the whiter color of the mag bulbs, but now that I know the red spectrum is good for you I can appreciate the warmer tints more.

    Yeah, those argon gas bulbs put out a nice color.

    I don't know if colors help or hurt my sleep. All I know is when the sun goes down my body thinks it bedtime. Man at time change when the sun goes down an hour sooner I'm all drowsy by 6. Maybe it's from working outdoors.

    Could be Mr. Bykfixer. I've been working dayshift lately- 7am-7pm. I mostly sit in my truck. I do good to get 4 hours sleep a night time I get home, eat and unwind. Most of the time I unwind on my phone and I feel like this blue light filter is helping me go to bed sooner. 6 hours sleep would be great.

    I always like to read in bed for a good half hour before sleep and Always use an Incan light in the dark, my partner is on her tablet thingy until 3 or 4 in the morning and keeps saying she`s just not tired! I think I`ll sugest this blue light filter to her

    Mrs. Katherine, I was like that, but sometimes I didn't go to bed till 5am. I was strickly a nightshift person, but I did this even on my off days. A while back when I was unemployed I would go to bed usually around 3am and get up around 10 or 10:30 am. This was before I gave in to having a cell phone or computer--before 2003. So, I guess staying up late is natural for me or was. I just don't need some android keeping me up later.
    I got in bed a little after 10:30pm last night which is good, but had to wake up at 4am just to get to work on time. I was 4 minutes late though.

    I want to thank candlepowerforums for upgrading my status.

    Uh, I just posted a smilie in this post, but the system posted another. Had to delete it because it was embarrassing.

    Really hope we can get a victory for the incandescents, I too love my LED's but just ordered a 4D Xenon maglite to add to my collection and I still love using my mini maglite with the incandescent, very easy on the eyes and bright enough to use to walk to the bathroom at night.

    I might even pick up a 3D Incandescent for fun.

    Also, this is making me want to break out my Wickedlasers Torch again... Really enjoy that one, bright as I could need and I can start my camp fire with it if I so choose.

    Yes sir mrsteel, I miss the old days when we didn't have as many choices and incan lighting was good enough. Flashlights were cheap with the most expensives ones just being around $20. If you got tired of the ones you had to whack every now and then you could just buy a better one and be done with it. I just hated that it didn't take long to get the lense dirty and then out of ignorance I would scratch it trying to clean it. I heard of surefire and streamlight from hunting mags, but thought they were specifically for guns and had a non adjustible laser beam which wasn't good for general purpose. I had a 2d maglite and a rayovac industrial safety light and I was purty well satisfied concerning flashlights.
    I guess LEDS are useful for me to a degree because they help to keep me awake while working on a vehicle at night--which is my favorite time to do that. I don't want to fall asleep under a vehicle and wake up with ants on me. My ol truck must love me because it seems to find reasons for us to spend some quality time together. Next up I need to check and maybe replace the wheel bearings because ol truck seems to be steering weird.

    I have posted other articles discussing the same MIT innovation, but this one that claims a product is now available is news to me. Might be years or decades, but incandescents more efficient than LED are coming. I am not sure the innovation can translate to flashlights, small or large, but I will be happy to see them for installed lighting.

    Me too chillinn. I wonder what the color temp will be.

    There is also a design in Korea using tiny mirrors to amplify the light output.
    Imagine the two combining.

    Right now I have a table lamp using 60 watt incan bulb to keep the wife's bird cage warm. The heat of the bulb next to the cage using the lamp shades as a funnel for the heat to rise warms up the steel bars, acting as a radiator and instead of some multi hundred watt thing it only uses 60. I don't think the bird cares about the tint. Hope not anyway.

    That's a good ideal bykfixer, I would like to try that if I ever hatch out some more baby chicks. Those big bulbs use too much electricity and they aren't real durable.

    As you know, light bulbs put out a lot of heat. It's placing metal objects near one that multiplies the heat radiation.
    Years ago while living at my brothers he used an electric radiator in his bathroom since his wood heated home only had one stove. The radiator did ok if he put it on max. One day I rolled it over to his porcelan pedestal sink and used the cermaic sink as an additional radiator. At first he was skeptical but after a couple of days had turned the radiator down to low.
    In his kitchen he would drink coffee next to a radiator with a jacket on. I slid a small table lamp under his mostly metal chair. Again he was skeptical. But after about an hour of sitting over top of a 60 watt light bulb he was peeling off his jacket. Now he uses table lamps near metal objects as radiators since even the curly fry bulbs he uses put off plenty of heat.

    My home does not have any LED bulbs in lamps. Just CFL or light bulbs so I really cannot say if LED lights affect my sleep.

    Not sure it matters now, but if you come across such a set up. 6" computer fans in one of the top corners of all the doorways spreads the heat throughout the house, making only one stove work everywhere. So the bathroom door would stay open, usually, then shut when in use. Not my idea, but I have seen this used to excellent effect. I am a huge fan of wood burning stoves, especially the small modern ones. I hope someday to have a need for and money for and get a Kimberly. Outrageously expensive, but super efficient, super neat stove.

    I've got a wood burning stove in my trailer. It burns so hot we have to open both doors even if it is very cold outside. Its one of those boxwood stoves. We have to feed it just right or it will put out too little or too much. I've also have 4 90 degree pipes mixed into my stovepipe to retain heat.

    This is my experience with wood burning stoves... 3 feet of snow on the ground, log cabin, all windows open, front door open, shirtless w/shorts, and fresh air. Heated front porch. The stove was a little big for this place, basically a full beer keg sized stove in a small room, but in the mountains, they don't mess around. May still be there, I am speaking of the only log cabin I saw on the New River, last property before the park.

    When he was married to x wife #3 they had 3 stoves. She got the two small ones in the divorce. X wife #2 got the old natural gas heater.

    He lives in the huvel my ancestors built when they first arrived to America from Germany. My great great grandfather saw things taking place under the Kaiser and got the heck out of there while he could. A few years later WW1 broke out. It's a half house where he built the first half thinking some day he'd build the other half. My brother added plumbing and a kitchen in the 1970's. And now he has "modernized" the ceiling lights to CFL bulbs when the 4 for $1 light bulbs kept blowing every few days.
    He's retired so I suppose if the lights he uses affect his sleep it really doesn't matter much.

    So, there we have it. Since the invention of LED lighting for home and office use, I couldn't stand that light. And I mainly stick to incans for my flashlights too, as the quality of their light is SO much better. As soon as just RUMOURS were there that incandescent light bulbs were to be ruled out in a few years completely, I started to buy them in bulk. Currently I have MORE than enough incan light bulbs to last for the rest of my life. I have chandeliers all over my home (even one in the toilet!) and these use anywhere between 5 and 16 bulbs. The larger ones can be switched in two halves, in the living room I have special bulbs having an extra low color temperature (the so called "Rustika" bulbs with an enormous filament, not even blinding when you look straight into them), half of these are 25 Watts and the other half has 40 Watts. I may have a total of around 700 of these candle-bulbs, so that will be enough for the years to come. LEDs as home lighting? NEVER! Not in my home, that is.

    The negative heath effects of CFL have been known for decades. What is new is UV leakage.

    I was raised in natural light. The sun is an incandescent light source. And you better believe it flickers!
