LEDs, the last spec.’s I looked at, had a mean time between failure (MTBF) of over 450,000 hours; approximately 51 years.

Enough for you?

Factor in what it costs to change light bulbs in some stairwells and emergency lighting units....and you don’t mind paying a lot for bulbs if they last for years and draw little juice.

“Are LEDs still $30 a bulb?”

No, this one is $100 (Special price !)

Ridiculous. And chinese made.

Using just 10 watts and a single LED component made in the USA, the LED light uses just 1/10th the electricity of an incandescent light bulb

That is a nonesense statement. It uses 1/10th the electricity of any type of light bulb whatsoever that uses 100W, including a 100W LED array. It uses 2/3rds the electricity of a 15W incandescent light bulb, not 1/10th.

The real question is what is its comparative light output, and will it make you blind or give you migraines?

How many ______ does it take to screw in an LED lightbulb?

The prime market today is commercial. A $99 consumer bulb doesn’t make much sense. BUT, if you have to send a janitor/maintenance guy to replace a bulb every few months, the payback on the $99 is great pretty much covered in the first year or two.

If a few micrograms of mercury can contaminate 7000 gallons of water, then you should worry. Otherwise, it may be reasonable to believe that’s hype from the LED-making company.

I’ll be convinced that it’s a good product when they are able to blow them off the shelves absent any government mandates.

“I’ve been switch to CFs as I can”

Just don’t call anyone in government to ask how to clean up the mercury if you break one. A guy in Maine did and his house was labeled a hazardous waste zone, It cost him just over $2000 to have a team clean and dispose of the mess.

Incandescent light bulbs are like old transistor tubes. LEDs are an actual electronic device and have similar qualities. If properly made they will easily last that long if not longer. IMO, LEDs will be the wave of the future. Lighting is responsible for a huge amount of energy use. LEDs use 1/10 the amount of energy than incandescent and florescent. My tip, save your money on the compact florescents and wait for LED lighting to be more affordable.

“that governments are trying to ban things that technology will eventually outmode.”

I agree — it’s pure gesture politics. Even our (Canadian)Conservative government has set standards, which will effectively ban classic incandescent bulbs by 2012. They had to do it to shut the ecowackos up. A lot of people actually believed that the only thing necessary to meet Kyoto targets was changing light bulbs, and getting a bus pass. Now, they're starting to wake up to the realities.

This particular LED has 50K hours of burn time (5.7 years of constant use)..

A bigger problem (at least they are honest about it

“Remember: LED lights are directional (like a spotlight). This EcoLED light has a beam angle of 100 degrees, which is equivalent to a wide spotlight. It is not appropriate for use in lamps with lamp shades or other lighting applications where light needs to be emitted in all directions at once. (However, it can be aimed at a wall or ceiling to produce radiant ambient light that radiates through the entire room.) Also note that this EcoLED product produces clean, bright “white” light, not the typical yellowish light produced by incandescent bulbs. Most people agree that our white lights offer far better visibility and clarity than common yellowish light bulbs.”

I agree with your math and I too would like to see them rated in lumen. According to the web site, they seem to be relating it to the output of a 100W incandesant bulb, though even that is suspect:
"Our premium 10-watt EcoLED white light bulb that replaces a 100-watt regular bulb. Lasts 50,000 hours and saves you nearly $450 in electricity over its life*.".

Kyoto is a joke, thank God we somehow managed to dodge that bullet in the 90s.

Also the 50,000 hours seems way low for an LED. Maybe I’m just used to industrial units that last upwards of 450,000 hrs. Still, 50,000 hours is 5.7 years... Not great, but a start.

In “light” of our previous discussions about the mercury in CFL bulbs ( http://www.freerepublic.com/focus/f-news/1835838/posts ), I thought that you’d be interested in this thread. Here’s a quote from the article:

“The mainstream push is towards compact fluorescent lights (CFLs), but consumers are not being told that CFLs contain toxic mercury. There’s enough mercury in a single CFL to contaminate 7,000 gallons of fresh water, and if Americans continue to purchase CFLs — then throw them away in local landfills — the United States will soon be facing an unprecedented burden of toxic mercury in rivers, streams, croplands and oceans.”

...and California is considering a state-wide ban.

The guy/gal that figures out how to replace all the current street
lights in the Los Angeles Metro area (presuming they give big
lifetime energy savings over the current lamps) will be making
a great contribution to the country.

But I hope they don't dimish the beauty I've experienced
when flying into LAX at night and looking down on one of the
greatest non-natural light shows ever!
