more logical

| Oct 30, 2021 at 1:00 | comment | added | Eugene | @WaterMolecule 100% and whole home no, but for many rooms in high latitude countries, pretty damn close. e.g most rooms with decently sized windows in most of Canada and most of Russia(although electric heating is very rare there) | |
| Oct 28, 2021 at 22:35 | comment | added | uhoh | ...but since they are more expensive, only if they are actually much longer-lasting. If not... LED Light bulbs burning out much sooner than expected and My Canister ceiling light bulbs, LED 65, BR30 burn out too quickly | |
| Oct 28, 2021 at 17:14 | comment | added | Shamshiel | I have yet to find an LED bulb that lasts anything close to 25000 hours even in ideal conditions, no matter what the box says. Certainly not an $8 one. Perhaps the lower lumen bulbs are generally more reliable; I tend to buy higher-lumen bulbs. (Though I have some 200watt-equivalent LEDs from some Chinese manufacturer that have held up longer than all my "regular" 60 or 100watt equivalent GE and FEIT LEDS.) | |

Thought of one practical example where you might always be heating at the same time you are using lighting: a ski chalet

| Oct 28, 2021 at 13:43 | comment | added | WaterMolecule | @PaŭlEbermann Except that there is pretty much no place on Earth where you would use the same energy. There are only very special conditions when you would always be heating your home at the same time that you are using lighting. The only practical possibilities that I can come up with is a ski chalet used only during the winter and an Antarctic base. | |

| Oct 28, 2021 at 9:45 | comment | added | ProfRob | "if you ignore the environmental costs" - and that's why we're all going to hell in a handcart. Roll on the day when those that pollute, pay. | |
| Oct 27, 2021 at 21:20 | comment | added | Paŭlo Ebermann | "Also, using less energy is better for everyone, especially if it comes from nonrenewable sources." – the premise of the question was that you use the same energy anyways (because it's needed for heating), so this is not an argument. | |

@Eugene: If you and the answerer are the only people in the comment section, you won't see the answerer show up in the @ suggestions.

| Oct 27, 2021 at 18:54 | comment | added | Eugene | Wow, talk about being proactive! But then again you are apparently a professor lol. Unfortunately, most people just replace light-bulbs when they burn out and you can't just leave empty/broken lights when you move out, or it'll come out of your deposit. P.S. why does you alias not come up when you try to @ mention? | |
| Oct 27, 2021 at 17:59 | comment | added | WaterMolecule | @Eugene Those are good points, which need to be considered. I will say that when I used to rent, I installed LED lights and took some of them with me when I moved (putting the incandescent bulbs back in their places). | |
| Oct 27, 2021 at 17:54 | comment | added | Eugene | This isn't an issue for enterprise users like municipalities, since they replace the fixtures as well, but if you e.g. unscrew a ceiling light and screw in a light-bulb shaped LED, you'll often find that the back of the fixture has 0 ventilation and the LED will fail in a fraction of it's design life-span. | |
| Oct 27, 2021 at 17:49 | comment | added | Eugene | There are 2 common real-world factors that seriously distort the maintenance calculation: 1- Lots of people rent and/or don't expect to stay in their current home for more than a few years, so any investments in really long-lasting lights are useless to them. 2 - LED lifespan degrades drastically if they overheat, which is a major issue, since "normal" light fixtures are still shaped for incandescents which generate almost all their heat on their front whereas their LED replacements generate most of their heat at the back, which is confined and unventilated in normal fixtures so they overheat | |
