I’d like to see these back in streetlights and vehicles as well!
Inside your house, wherever you spend the most of your time, you should use exclusively incandescent. Anywhere else, like closets, outside or the cellar, LED is fine. Your body NEEDS the near-IR light and we don't get enough of it because we don't have woodburning fireplaces and we don't go outside.
If you use red LEDs, you can also use the room as a darkroom and develop prints.
You can efficiently give yourself cancer by witholding the "inefficient" IR heat.
I think we often associate incandescent with low light temperature, which seems to be better overall for things like circadian rhythm etc. While cost wise, incandescent isn’t as efficient, I would love to see more of that color spectrum back, over the bright white of most LED’s that people are switching to, in their homes especially.
Agreed. Incandescent is superior, but the fuckers (Trump) made them illegal.

What lamp do you usually buy to avoid UVC but with a good spectrum in IR?
I bought some cases. About 1000 lamps for the next years
You dont get uvc from incandescent. To get uvc from a fluorescent (mercury plasma) bulb, you need it to be void of phoaphor and made with a quartz tube. Otherwise, UVC is only present when you are in proximity to welding. Uva and uvb are what you get sunburn from, and what gives you that unpleasent tingling when you're in direct sunlight at high-noon. Its best to avoid direct sunlight mid-day and stay in shade amidst greenery, because Rayleigh blue-scattering is minimized at that time of day.
I have many halogen bulbs (metal halide) but only because i couldnt get incandescent
I am beginning to think the vitamin-d deficiency is a huge debacle, reversal of cause and effect where D3 is a byproduct of UVB ionizing stress and an indicator of sunlight exposure more than an overall indicator of health
The ir spectrum of incandescent matches full-sun more than metal halide. Its the green and blue light component of halide bulbs that provide a higher color temperature, thereby simulating a higher filament temperature. The old "daylight" incandescent bulbs largely only filtered some of the red light, also simulating a higher temperature. Nonetheless, halide bulbs are a suboptimal light source, particularly at night from a IR health perspective.
I understand that is the current concensus on the topic, however no science is settled. Regardless, I won't suggest anyone act on mere speculation on vitamin D being unnecessary since it certainly can't hurt and more likely helps.
If you compare total energy magnitude of incandescent, halide and late afternoon sunlight under typical circumstances, the incandescent yields almost twice near-ir than halide, and this even with low frequency kurtosis. Of course this should be obvious since the total electrical wattage is also almost double.
why red 🤣 how bout pink? he he 😂
My solution is to use a 3in1 lamp base expander and just put 3 halogen bulbs in place of the one incandescent.
Its true the sun radiates both atomic excitation emission frequencies and blackbody radiation, more akin to the halide group.
I would be surprised if monochromatic was healthier than even the most average LED warm white bulbs.
I want bulbs with as many lumen as possible and I would want an extreme brightness screen so I can comfortably see it even against a bright window at noon. Locking light out during the day so you can see the screen is probably as bad as having much blue light late at night.
That said, I almost never have issues falling asleep.
If any specific wavelengths matter, LEDs will either have to produce all of those or there's no alternative to an incandescent light. But I suspect the human genome mostly developed absent any artificial light, including fire, so it's probably healthiest to get out during the day and sleep at night. It's not the most productive, especially where nights are long but that's kind of what we are built for.
Just incandescent ones since everything else was pretty expensive for some reason
Yes the led "filament" bulbs are utter flickery trash. They also lack spectrum in the yellow and far red region rendering them depressingly dim.
Proclaimed superior by moronic tech geeks, LED manufacturers and the scientific governmental complex sponsored by chinese industrialists.
And anyone that installs lights of all kinds for a living
This photo looks like a genuine edison bulb, but try to buy one and its the simulated LED filament trash
You know, not that long ago they piped gas to every room for light fixtures. That's why the old-style chandeliers have gas-valve keys
I know all about that. My dad was a professional light bulb salesman and installer. That's a whole different story, now you're bringing commercial lighting into the mix. I'm only concerned about domestic lighting.
If you went that route, now youre dealing with natural gas contaminents. You'd only want to burn propane in a situation because its a refined petroleum.
Regular led bulb > regular incandescent imo
They fail less and have less duds out of the package(in my extensive experience) and don't heat up to dangerous temperatures (which causes many issues beyond the fire hazard). They also use 1/10th of the power
The positives for incandescents are that they don't dim as much over time and they are cheaper to make.
The things I care about as an electrician are the things in column A.
I used to be in your camp. Efficiency and longevity was my primary concern. Then I learned about intracellular photosynthetic production of melatonin.
Also, as soon as they started sponsoring the CFL bulbs, the incandescent bulb quality went through the floor and what would last years started lasting months.
Yeah, that's about as interesting to me as astrology. Light is light. What changes is the spectrum and that can be set at any wavelength with LEDs. There is no meaningful amount of anything else radiating from an incandescent light. The fact that it's a piece of molten tungsten doesn't make the light different than a cold diode of the same color.
Ok. I guess I don't know what I'm talking about. Next time I'll call my electrician before I read any scientific literature.
Yes I know. I deliberately use mercury plasma to create disinfection lights. I was speaking about the metal halide lamps. I could not find the spectrum of any but some that are sold as full spectrum specify that people should not spend there more than few minutes because of the UV. So the question is. Is there one or more full spectrum minus UVC on the market, not for plants only.
Some specify of the dangerous UV emission because they are for growing plants. Are there some specific brand and model that have a full spectrum from deep IR to UVB with no or little UVC and a spectrum similar to the solar one?
UVC is highly carcinogenic. You don't want to be exposed to anything that emits it, even for a few minutes. It can also burn your corneas and cause blindness. UVC doesn't occur naturally on Earth because it is filtered by the ozone layer, scattered by the Rayleigh effect, and absorbed by oxygen gas. Metal halide bulbs, which are mercury vapor bulbs, do produce UVC, although they have a coating to absorb most of this spectrum. I was mistaken in earlier posts, confusing halogen with metal halide. Yes, you do not want to be in close proximity to metal halide bulbs, not only because of some UVC emission but also due to their intensity in the UVB and UVA spectrum.
Snark all you want. If you think your incandescent light bulb has some kind of health benefit, I have a bridge to sell you.
Would you say the same of sunlight?
Just to be clear, the most beneficial region emitted by incandeacent is near-IR. The specific frequencies that stimulate melatonin generation in the mitochondria is not known, but it is believed to be between 700 and 1100nm
I use UVC to kill bacteria and mold. 10 minutes is like exposing something to the sun for one day
The sun is not a small band of glowing tungsten. Troll harder
great thread:
I love it here 😂

Since it wasn't mentioned in the replies yet (*I think...), red light only is not the solution.
You need to max out Daylight similarity.
Therefore look for lightbulbs of any kind you like with very high CRI (Color rendition index) and flicker-free dimming.
*
CRI 99 is almost indistinguishable from daylight based on spectrum perspective
