Climate Change Thread

When I see opaque bulb I can easily guess why is it made that way and what kind of light it emits.

A standard incandescent bulb, with the glass or plastic out cover tinted green, is still emitting the same light frequency, even it is re-filtered by the particular coating being used.

Being picky, I would say "limited translucency." A truly opaque bulb would emit no visible light, only ultra or infra wavelengths. Just being snarky.

You may easily guess that when I say I don't like that kind of light I don't go into comparing wavelengths, frequencies or voltage. It is just a feeling that doesn't need any intelligent substantiation except one - it feels like a hospital.

Then your snarkiness (is it a word?) is ill-aimed. The word "opaque" was used by Papewaio and I believe he is an authentic speaker of English. Since he used it I assumed it was acceptable. But your correcton is sensible. From now on I will say "the bulb that Papewaio terms opaque". It will make communication a little awkward, but accuracy matters.

When fitting LED lights, the key is the color temperature. The first LED bulbs were higher temperature bulbs, which gave them a (ironically) cold, bright feel. This is no longer an issue. Most LEDs should have the color temp on the package, look for ones in the 2500-3000 K range.

They have gotten better.

Concur. I have three incandescent lamps in my office and leave the sickly flourescents OFF whenever possible.

I don't think I've had incandescents in my home since I was quite young. Actually, I suppose I still do; my old nightlight might be around somewhere.

They're still the majority in private settings, but current figures indicate they more-or-less no longer exist in commercial or industrial settings (in the OECD world).

More interestingly, outside the OECD world kerosene plus CFL beats out incandescent.

Kerosene!

My house is wired with a central ceiling mount (it's not uniquely Ukrainians) and Fluorescent bulbs always leave the room dark and shadowy. I have a halogen lamp on desk, another fluorescent lamp above it (that I never use) and an incandescent by my bed. The Incandescent, despite being in the corner, light the room almost as well and the fluorescent on the ceiling.

I'll grant you they're better, but they're still crap.

My friend's aunt who lives on the Navajo reservation used to use kerosene to light her home because she didn't have electricity. I was pretty surprised to learn people still use kerosene for anything other than camping in the US.

That is pretty rare, but more likely in poor areas such as the larger reservations. We also lose homes and families every year to people using kerosene heaters indoors without proper ventilation. Not common, but still happens.

'Opaque 1.
not able to be seen through; not transparent.
"bottles filled with a pale opaque liquid"
synonyms: non-transparent, cloudy, filmy, blurred, smeared, hazy, misty, dirty, dingy, muddy, muddied, grimy, smeary
"the bottle was made of opaque glass so that the contents could not be seen"'

So a white light bulb or pearl using the marketing terms where you cannot see the filament. CFLs use these almost all the time.

CFLs have to. If the coating inside the the bulb is damaged in any way, they emit unhealthy levels of ultraviolet radiation. Add that to their mercury content, and I think CFLs are actually kind of awful. LED bulbs, which are getting more reasonably priced, are a good alternative.

This thread is moot. President Trump will rip up the Paris agreement and we will just have to bank on Elon Musk somehow whipping his engineers into making a magical CO2 extractor machine.

I'm honestly hoping for at least a continuation of the Paris Agreement from the USA, because the Europeans will stick to it.

Except the Paris agreement has more then the US involved

We can just install an enormous, coal-powered refrigerator (= energy pump) there and make China pay for it.

Without commitment from the US to reduce carbon emissions, we are not going to make our goals. You know this.

[Greyblades]

Had China agreed to the Paris agreement? Without commitment from the Chinese to reduce carbon emissions, you are never going to make your goals, USA or no.
