Incandescent bulb’s future dims

Because of the quote of a light bubls energy being lost to heat. For the most part in order to generate light you need to heat up a materail to the point that it glows.

In an incandescent bulb, yes. In a florescent bulb, not so much. Pretty much by definition. There are many ways to use electrical current to excite particles so they emit light. Some of those means produce more heat than others.

I'm leaving LEDs aside, because I don't think they're relevant to the discussion until I start seeing them on the aisles at the local Home Depot. When I see them, I'll buy them, unless they're absurdly expensive.

Yes, I know the difference, I made a mistake. Acknowledged three times now.

Mercury emissions by a CFL lamp from electricity consumption over its lifetime is about 2.4mg of mercury. Emissions from an incandescent light bulb is about 10mg for the same period through electricity consumption. Therefore a CFL bulb emits 76% less mercury over the same time period. However, mercury stored in CFL bulbs is perfectly safe unless the glass is in someway damaged, in which case the bulbs can then emit mercury vapour. If the mercury from a CFL was to escape it would total 6.4mg, a 36% reduction on emissions from an incandescent.

I’m talking about BREAKAGE! We’ve all lived very long with regular bulbs. When these new bulbs break you have to go HAZMAT!!!

We are already seeing, handcranked led flashlights, In a couple of years we could easily have these in the form of desk lamps, and reading lights. All we need to do is find a way to have them glow with a softer light instead of blue.

I was picturing a modern double-walled stove, not a pot-bellied or Franklin stove. The one my Dad had was basically a two-foot by two-foot box, insulated, the exterior warm to the touch but it wouldn’t burn you.

I have all the oil lamps I need, but here’s the funny thing — my mom bought some of them as pieces of decor. They’re a nice homey touch, but they don’t do anything. I have lamps, I have fuel. What I lack is wick cord.

It’s always the small stuff that trips ya up.

I guess you missed reading this-

mercury stored in CFL bulbs is perfectly safe unless the glass is in someway damaged, in which case the bulbs can then emit mercury vapour. If the mercury from a CFL was to escape it would total 6.4mg, a 36% reduction on emissions from an incandescent.

By the way, you have 50 milligrams of mercury in a conventional tooth filling for a cavity.

Sorry....don’t want those light bulbs EVER!! Nanny state crap.

I buy my wick cord in 30ft. rolls for my 50 or so lanterns from the 1800’s from Woody. Hobby of mine. Check out his site - he sells everything and that includes parts. Friendly to talk to also.

Out of curiosity, do you have ionization type smoke detectors in your house?

Some of the high-end — I’m talking $250 per — LED flashlights are considered non-lethal weapons. No joke. Cops are actually trained in how to use those flashlights to temporarily blind a suspect.

Then they hit him on the head with the flashlight, but that’s another part of the training. I have a friend who’s a POST trainer, and ... well, never mind.

I have LED flashlights. One is charging in a wall socket in case the power goes out. Another is on my keychain. Another is in the center console of my car. And another is in the inside pocket of my favorite jacket. I like redundant backups, and I hate it when I can’t see,

The question is, when will I be able to buy an LED lamp that will screw into the socket of my home light fixtures? It’s a mature technology. We know it works. We know that it draws a tiny amount of power for the same amount of light relative to incandescent and even compact fluorescent bulbs. It’s environmentally responsible, cost-ffective, and long-lasting. So where the hell is it?

As far as the color goes, LEDs can emit any color. You can tweak the electronics, or you can just paint them. Spray dye on the diodes. seriously, that’s a non-issue. A few years ago, I threw a valentine’s day party where the whole house was lit in pink. How did I do that? I wrapped all the light shades in pink saran wrap (Brits call it “cling film”).

I DETEST fluorescent bulbs in any form.

I will hold out / hold on until LED bulbs are affordable. C.Crane Co. sells LED’s (equivalent to 75-100 watts) for about $60.00 ea.

When the price becomes more competitive, I’ll be near the front of the line.

Politicians are stupid. These bulbs don’t work in refrigerators or stoves. There are no “night light” compact fluorescent bulbs. They don’t fit in all old fixtures.
The cost of disposal is conveniently passed over, but we all know that the politicians will sooner or later have to impose a disposal tax.
I take it back. Politicians are not stupid. They are fascists.

I live in a high rise apt with hard wired smoke detectors....hope that helps you.

[rmh47]

Sorry. I didn’t see the other replies until after I had posted.

[Westlander]

Too pricey for $60. Rumor has it that by 2010 prices will dramatically drop for LED’s. In the meantime you can buy 48 CFL’s on eBay for $50 and that includes shipping.

[HamiltonJay]

CFL’s are OK for some applications.. say a porchlight where you will turn it on and leave it on for hours, and it doesn’t matter if it took 15-30 seconds to warm up and emit its full light output.

However in a situation where you want INSTANT ON like say a bathroom at night, or most indoor room applications they are a poor replacement for incandescence.

There is NO WAY I will replace ever bulb in my house with CFLs. I have tried them, and use them where they work for me, but they are not equivalent to an incandescent.

Make them illegal, and I’ll just become a criminal and get them on the black market.

[maine-iac7]

Ahem, the big 3 light bulb makers have already announced they will no longer be making incadescents so this proposed law is useless.

And who do you think is behind the scenes? Especially since there have/are other better alternatives - or would be if they were allowed to produce?

Someone should be ferreting out who owns stock that will bring some very big dividends on the new bulbs...

(BTW, I believe it's spelled "incandescents"? Gonna embrace 'em, aught spell 'em right, right?)

Also, BTW, I have some in my house, but not in all lamps. They dont' work in my lamps that run on the motion detector switches - they flicker like mad - and from reports - can be dangerous. I also find them uncomfortable to read by. So I have regular bulbs for those applications. Should be MY CHOICE - not dictated...(and for a product that requires hazmat 'rules of engagement' to clean up should one break, just how is this passing the CDC criteria for doing one of the FEW things big Gov's IS supposed to do - protect us from hazards that we can't ourselves. For months now, almost on a daily basis, we hear of new recalls of anything 'China' = and then we force these on everyone? (Doesn't pass the smell test.)

Meanwhile, I'm stocking up. That said, if the "proposed law is useless," why is it being implemented???

Ahem
