The kind of father I am going to be, lmao. Saying batshit so my children think that I am actually insane, while having the ability to provide to the family and keep a good life. I think this is one of the most fatherly skills. A dad can come up to a son and say things like “led lightbulbs are bad, they don’t warm the room like the old ones” (my dad actually said that, while working with electrical engineering).
…I mean that’s actually a thing, the electricity savings on your power bill are reflected in your heat bill. Canadian farmers use a single 100 watt incandescent bulb in a 4x4 shack to keep the water pump from freezing at minus 40. Never mind the idiocy of LED tail lamps in cold climates.
Wasted energy isn’t just heat, it also includes chemical energy (chemical bonds), kinetic energy (noise and vibration), activation energy (chemical reactions), and light.
So a lamp that heats up the room but also makes noise is not using its energy 100% efficiently. Because the noise is not wanted.
The point was we want the heat from them not being 100 percent efficient…now consider why you’d bother with a LED with a heat circuit when incandescent exists.
I don’t think you understand their point. Typically, heat is the only undesirable byproduct of electrical devices, so the less heat it produces, the more “efficient” it is. However, if what you want is heat, then all devices are 100% “efficient.” (Minus any EM or kinetic energy that leaves the area as anything but heat)
A 100W incandescent light bulb and a 10W LED+90W heater are exactly the same in terms of how much heat they produce for how much energy they use, with the bonus that when you don’t want that heat, you can turn off the 90W heater and have the same light for 10% of the energy expenditure
But you’d have to replace it often. The space heater can also have frost guard so it will turn on when the temperature goes down. Imo it’s the better option
200 euro or kroner or whatever they use for a fire starter of massive overkill vs a light bulb, which lasts far more than 1000 hrs especially if not switched off n on.
Oh no, you have insulted my currency, I think? Guess I have to fold and agree that an old bulb with a rated lifetime of about 1000 hours, realistically 800 hours, and an anecdotal lifetime of 1000000 hours is the better option. (Notice my use of sarcasm)
Especially as it’s half the price of a product made to guard against frost that lasts basically forever. Because on the north American continent, it is much cheaper to have something that you just run day in and day out instead of only when needed. How much is 400 kWh in CAD? You can figure it out, but don’t bother replying, or do, I don’t control you
In Canada ain’t nothing for cheap. Except the light bulb.
Jokes aside until Amazon started bringing us cheap crap there was no practical low cost alternative, aside from gutting a coffee pot or something. I fixed an old water trough once that was heated by a 240v stove element brazed to the stubs of the old 120v one that had burned out. 2kW / 4 = 500W which is about the right power level for this job.
Stove element from the dump $0, Canarm watering bowl element $70

I replaced an incandescent bulb in my basement with an led, and my pipes froze the next winter. Took me a minute to figure out why.
As long as you’ve got some form of heating running, every electrical device in the room is ~100% efficient.
Also, because this is absolutely hilarious: They make heated LED lights for use in really cold places.

You’re right, but that wasn’t his point, he’s talking about all the electrical devices being 100 percent efficient and heating as separate.
Why not just have a small cheap space heater that lasts forever and for light source, the LED?
Because a light bulb is just a mini space heater, and it does the job.
But you’d have to replace it often. The space heater can also have frost guard so it will turn on when the temperature goes down. Imo it’s the better option
Show me this magic space heater that’s cheaper than 12 light bulbs and lasts that long.

Looks like crap, they discontinued the better variant (200 W) that was cheaper.

I don’t know what 12 old bulbs cost, but I know the life expectancy was about 1000h or so. I wouldn’t pick it anyhow, the heater is cheap as dirt
Edit: actually a 60 W old bulb is 101 SEK

I’m pretty sure you’re just kinda dumb at this point.

Actually I agree, it’s a pretty good source of heating elements. I’ve scavenged from some old toasters and sandwich iron
