Bees wax versus tallow. Candle versus oil lamps.  Whale oil versus petroleum oil.  Oil versus gas.  Gas versus arc lights.  Arc versus incandescent.  Incandescent versus halogen versus xenon versus fluorescent.  And now led.  The wheel goes on and on.  I bought my first cfl 20 years ago.  I retired the last of the oldest ones 2 years ago.  I'm awaiting the death of the rest so I can justify replacing them with the new leds. Some cfl were horrible but those from well known manufacturers performed well the crummy ones performed badly.  My first forray into leds involved wiring diodes with a resistor for 12 volt units.  Those early ones with the first flawed manufacturing processes really were horrible.  Too blue with bad quality control and cheap components. Fast forward a decade and off the shelf units from national retailers are cheap and longlived.  As to the light quality Nothing holds a candle to daylight if you will pardon the play on words.  As to complexity I would say leds allow you to lessen the complexity of your power generation so it should count as a plus for them.  One of the main sources of complexity and failure is the driver which has to regulate voltage and also fit in the tight package of the traditional Edison bulb design.  Think of the screw in leds as a stopgap measure at best.  More and more the new units are enclosed with a separate driver to control one or a string of fixtures.  These new gen ones are modular, replaceable and extremely longlived. Also since they generate very little heat their enclosures are much less complex.  No metal junction box and elaborate heat dissipating solutions incandescent lights require. Available in many spectrums based on taste and task. Stick to well known manufacturers do your research and you will love them.

I find to very odd, that as LEDs operate with 2-3 voltage and you use 230 voltages from the wall socket, it is 100 times more they need, so we use energy to transform energy: also need resistors, which heat up usually more than the LED itself..

If you have right voltage, you dont need resistors or/and transformers with LEDs.

I found this monster sized incandescent the other day and realised I would have to post it here!

This 1000W bulb was run on a dimmer switch (usually underpowered) in an outbuilding workshop at my parents old house. They built the workshop to help construct the house in the early 80's and it wasn't demolished until around 2004. So I reckon its has had at least 20 years of use of fairly consistent use and the filament looks as good as new. It wouldn't suprise me if my dad bought it second hand as didn't remember him having any spare giant lightbullbs of the same type.

What an eye opening post. Wow.

I searched through all of the posts that mention battery back-ups (electrical inverter power), because that is what is most relevant to me in Haiti. I buy CFL's, not because they "save the earth" or are "cheaper in the long run." I buy them because they let my inverter power run for a longer amount of time. In fact, in Haiti, the corner-store boutiques refer to CFLs as "inverter lights," because they help inverter power to last longer.

I was wondering how these calculations hold up when taking this matter into account. What about the cost of a generator being run more frequently? What about the decrease in the life-span of an inverter battery due to increased cycling? What about the strain on the actual inverter itself?

Unfortunately, I could not find any direct references to research in this vein. Perhaps one of you could point me to some...

I'd be happy to provide numbers (cost of batteries, cost of fuel, generator servicing, etc.) if someone wants to try to calculate. Or, if someone has a suggested calculation, post it here and I'll plug in for the variables.

To my mind, the discussion begins and ends with incandescents produce heat. I don't do heat. Most of my life, we had no heat, other than the occasional fire, solar in the late 70's, early 80's was terrible. Then as an adult, we couldn't afford it. I have heat now, but wouldn't use it, if I lived alone. As long as the house doesn't dip below 40 degrees, I'm good.

Cool thread. Any idea where to find incandescent lighting experts? I'm looking for engineers who know about manufacturing parts - and have a good breadth of knowledge about the range of incandescent lights out there (in various frequency ranges). I'm working on a project and looking for consultants, engineering students, or whomever has the most experience in this "old fashioned" technology... Easy to find LED experts, of course

I might posit that LED flashlights/worklights are greatly superior to  incandescent. Much brighter, and they give longer battery life.
The reason that they aren't as pleasing to use for interior illumination is because any given LED can only emit one wavelength of light, so to make "white" light, it is actually a composite of emitters. It kind of works, but your eye/mind seems to know better.

i use all 3 for different applications, here is why:

incandescent, for heat and light, for the chicken coop in the winter, when there are days they are completely snowed in and it might take some time to shovel a path to them to let them out. the light helps keep their water from freezing entirely.

fluorescent for indoor grow boxes, because they are fucking everywhere and last a long time, and dont make as much heat as incandescents(important for an almost fully enclosed grow box, i prefer to smoke and/or cook what im growing AFTER its been harvested), i stock piled CFLs as they are everywhere they were being given away for free, so have a bunch in storage. long flourescents are also available everywhere, folks get rid of them for free so much.

LEDs, for the general lighting in the house. these were also being given away for free in a lot of places. i don't have them as stocked up as the CFLs, but have enough for most of the rooms in my house. i like how efficient they are electicity wise. id like to learn to make LED arrays myself, so i can grow more indoors, year round microgreens, clones and seedlings to market and plant in spring.

i don't know if/how significant differences there are in the industrial processes for making them vs other bulbs, at a certain point i consider that splitting hairs, and greenwashing. i take no responsibility for the world capitalist industry has built for us. im doing what i can with what i have, and i have little to no power in these dynamics. my impact is insignificant compared to systems beyond my control, challenging those systems, like the military, and industry itself, are my priority, not peoples consumption habits, which are divisive, and unecissary, egoic and elitist, a distraction from organizing our power as people to challenge the destructive systems.

As for heating goes, we live in a newer mobile home, rather efficient design, lots of south oriented windows with central oil heat, i shut the vents to underused rooms in the winter, as well as my own bedroom. Its one of the most efficient homes ive lived in in Maine(not saying much, our housing stock is getting super old, poorly insulated, drafty). Its more efficient then electric heating, both cost wise and on the environment.

We'll be using more wood this year in a conventional fireplace. I'm trying to get permission from the landlord, and help with buying materials, to build a greenroom on the deck, to get some passive heating of the house, and a warm entry into a grow room. Plan to extend the greenhouse out from this 3 season deck, connecting the two, and use a rocket mass heater to keep it all warm. On sunny winter days i plan to just open the porch door to let in all the excess heat from the greenhouse/3 season room, into the house, which is already south oriented and toasty on sunny days.

It's 2017, and I still use LEDs as my favorite illumination.
My favorite USB powered light bars are all Piranha LEDs, and
My favorite flashlights are all KREE
 
I agree. Here's the link: http://stoves2.com
