Behold the $15 LED light bulb

I think its great.........but dont tell me what kind of light bulb I can or cant buy. Thats just stupid silliness.

I love how liberals talk about personal freedoms. They're all for it......as long as you have to do it their way.
nobody is telling you what kind of light bulbs you can or can't buy. They are telling manufacturers what kind of light bulbs they can or can't produce.
Well thank you for showing the logistical difference between fascism, socialism and free capitalism in one sentence.

It's not that you can't BUY incandescent bulbs... you just can't manufacture or IMPORT them. Boy that makes me feel so much better.

You realize of course that prohibition did not stop the OWNERSHIP of alcohol... just the transport and sale.

Spaceba Comrade!

I rather doubt we will have a black market in light bulbs but who knows. This country is full of kooks.

Yes, and they are the ones saying that CFLs are a good thing and grandma's thermometer is a threat to all life in a 2 mile radius.

Kooks indeed. And a black market is guaranteed because every time you get rid of a useful technology with an artificial reason when no crisis exists, you get one.
 
We should elect the Koch brothers to the white house. Don't you agree?

Look at the good side
-Drilling for our own resources
-Mining for our own resources
-more nuclear
-strong anti-Keynesian economic approach. HELL after the cluster fuck of the last few years through the US and europe...I'd think that's a good idea.

Sounds pretty fucking good...We can have our cheap light bulbs back.

For president???

I can get 2 bulbs at the dollar store.

Do these last 30xs as long?

How long do I have to use it to make up for the fact that it costs 30 times what I pay for my current bulbs?

An LED should last a generation or more unless you drop it or somehow apply enough force to it to damage it. Its a solid state device. They should last longer than the fixture you screw them into. You'll be able to pass them down to your children and them to their children.

The energy usage is about 10% that of an incandescent. Not only do you save 90% in energy costs but you also save in the summer because you won't need as much AC with less heat being generated by your light bulbs. You save in the winter, too, if you heat by gas, because heating by gas is more efficient than heating by incandescent light bulbs.

I have all flouros right now but when they burn out SEVEN years from now or so, I'll replace them with LED's and not have to worry about changing another lightbulb until I'm well into retirement or even dead.

If you teabagger nuts ran the Navy our submarines would all still run on diesel.

You can manufacture all you want as long as they don't enter the interstate commerce.

Go for it.

Just goes to show how we should NEVER trust the enviro-nuts to make these decisions for all the rest of us.

I've been designing LED lighting with the newest of new generation of white LED products. And the one thing that I've focused on is lifetime. The physics of energy density and heat transfer from an LED is MUCH different from an incandescent in that the volume available to shed heat is substantially smaller. Even the best heat sinked design will put the junction temperature of an LED in a constant ambient range of 50 to 70 degC.

Lifetime curves are affected by the breakdown of secondary phospors under temperature and changes to the LED junction itself. An L70 (70% initial light output) lifetime is over 5 years right now. It is NOT projected to get "better". While this is GOOD -- it is NOWHERE NEAR what Oopydoo claims is ETERNAL...

BTW:: LEDs don't die --- they just "fade away". (generally) So you can leave them to grandchildren, but they will be pretty dim and not white after 6 or 7 years from date of initial use..

Furthermore, the heat produced by an incandescent in wintertime is completely efficient. Meaning that whatever is not produced in visible light is produced in infra-red heating. There is very little emission in HIGHER freq ultra-Violet like in a flourescent. So a WATT burned is a WATT burned. And it goes entirely into heat. NOTHING is wasted in the wintertime indoor scenario. You can argue about gas heating til the equinox, but that's a fact and it was LEFT OUT of the GOVT definition for lighting efficiency on a yearly basis.

Teabaggers my ass -- the REAL danger is clear --- ain't it??

Touche. I defer to your knowledge.

However - you are INCORRECT on this point. In terms of energy - gas heating is more efficient than heating by an electric heating element. A lot of energy is lost when gas - or coal or whatever - is burned to run a generator to make AC which is then sent through transformers and miles of transmission lines and then through transformers again before it gets to your electric heater.

Well sure.. Oopydoo.... If you're counting efficiency all the way back to the dinosaurs... Please remember to nag all of us how evilly wasteful electricity generation is when we're putting 25KwHrs into each EV Car fill-up...

Better update that will !! Give the grandkids that collection of 50 state thimbles that I know you must have instead of those LED bulbs.. :tongue:
 
Flac, you will put less CO2 into the atmosphere from that 25 kwh you have put into the ev than you would driving an ICE an equal distance. That is because of the inherent ineficiency of the ICE.

Not less than what you'd put in from a hybrid however. And I'm NOT primarily concerned about CO2.. I'm concerned about the TOTAL effect on the environment.. MOSTLY real IMMEDIATE pollutants like NOX and SO2 and Mercury and radioactive fly ash..

BTW: most ALL the inefficiency of ICE comes from idling and braking in traffic conditions. Whereas Hybrids and EVs don't consume (ignoring 200W stereos, air conditioning, and heating and LIGHTS!) when they are idled and can scavenge back energy from braking.

But the point was --- the GOVT analysis of the "economy" of EVs IGNORES the same larger system metrics (like charging, distribution and generation losses) that it ignored in the "efficiency" guidelines for incandescent light sources.. Or like when they IGNORE the cost and pollution for mainline generation using traditional gas,coal,nuclear to fill in the performance gaps for any added wind generation..



Not very rigorous or even disciplined at all... Govt in general does tremendous damage to real engineering analysis...

oh good and an electric car will take hours to charge and barely get you across town... Electric cars take society a step back not a step forward.. Efficiency? 500lbs of batteries and several hours to charge, equals about a third usually less than that the distance of a full tank of gas. Not to mention the difficulty in finding a place to charge the car..

The internal combustion engine gave freedom to the masses. Freedom to go and move great distances cheaply and reliably. Current electric alternatives cut that freedom down a great deal.

You seem to think its all good right now. Sure you don't have to live with it and as long as its a idealistic fantasy you won't have to. You can afford your dream of wind generated electric utopia because its a dream fueled by the idealistic dreamers and companies making money selling it to you. Sadly the rest of us cannot afford to live in your fantasy. I for one have to live in reality where windpower is unreliable and limited, and electric cars are powered by batteries which adds weight, increasing power required to propel them and taking 12 or more hours to charge giving me about an hour or two of travel time before needing another 12 hour charge and finding a place to do it, as well as the batteries needing replaced sooner the more I have to charge them...

I will live in reality thank you...
