Home Depot later this year plans to carry a Philips LED bulb designed as a replacement for the common 60-watt incandescent. The bulb, now called the 12-watt EnduraLED, will be available by the beginning of December and will cost between $40 and $50, representatives from Philips and Home Depot said today. Home Depot started selling a line of LED bulbs under the EcoSmart label earlier this year, which includes both spotlights and general-lighting LEDs. The Philips bulb will likely be sold under a different name than 12-watt EnduraLED, Philips representative Silvie Casanova said. I have been using an early production version of the Philips bulb around my house for the last few days. At first blush, I'd say this is the sort of product that could finally help nudge out the beloved, if wasteful, incandescent bulb....

I’m surprised the LEDs use 13 watts/60 watt equivalent. I think the last CFLs I got were about the same.
I recently used some of these for caving. They worked GREAT.>>>>>>>
Pretty neat little LED flashlights!
City governments have been dealing with this sort of problem. Many cities have been replacing the traffic signal lights with LED bulbs to save money, and during snowy winters, they've found that snow and ice cake the bulbs, keeping them from being seen by drivers. The old bulbs, which generated a lot of heat, didn't have this problem.

“$40 or $50 for a bunch of mercury to be tossed away”
Without making a case, pro or con about the price, you have one thing wrong about LED bulbs. Unlike florescent bulbs, they do not contain mercury.
They are, also by the way, much more energy efficient (electricity conversion to light) than florescent bulbs and do so creating less heat than either florescent or incandescent bulbs.
However, with regard to the current price: Their price is high at this time, because this is the beginning of the technological and production changes to make them a “mass market” item. Give them time, their energy efficiency, not a political agenda is what will slowly grow their market over time, which will bring production levels up and prices down. Don’t worry, there will be enough 1st and 2nd-wave buyers to get that process started; there always are.
Give me your address so I can call HAZMAT on you. While I’m at it, someone will be by soon to confiscate your arsenal too.
It’s for the children...and the environment you know.
So do you pour mercury down the barrel or do you cap off the end and fill the entire barrel? How long does it need to soak?
I have a revolver that has some buildup.
we live in a litigious, nanny state and need to take the country back....FUBO
I believe Al Capone had a similar idea in regards to a governmental ban on a product... I forget what they called it.
>> To complicate things, since LED’s tend to dim over time (known as lumen depreciation), do you compare the watts per lumen of the bulbs fresh out of the box, or an average of the watts per lumen over the life of the different bulbs?
Ow! My head. It hertz.
The Molybdenum?
NASA has found that the primary cause for satelite failure can be attributed to Tin whiskers in the satelite. That’s why backup circuits either do not work at all, or only buy a year or so of additional life.
The thing is, even in areas where Molybdenum is found; sealed circuits, or circuits that have little or no airflow will also self-destruct with the RoHS initiative.
Not uneducated at all, actually a very good question.
The latest papers presented at the RoHS conferences say that there appears to be a ‘Gestatation’ period, where atomic pressures build over time (3-5 years typically), where the Tin atoms finally reach some internal pressure, and a crystal is formed. From there, in a matter of months, a whisker that measures up to 0.300 inches can form. These whiskers form without regard to electrical flow, temperature, atmosphere or magnetic field. They are a random ‘bullet’ that may just be a whisker hanging out in free space, hurting no one. Or, it could be a whisker that jumps over to an adjacent pin on an IC and shorts a signal out. This would be like tying random pins of a chip together - the results could blow a fuse, they could mean your computer won’t boot, it could be a pin that is seldom if ever used and you won’t notice a failure in most cases - but get new weird behaviors when you try to use a seldom used feature.
But, the bottom line is this. 95+% of the Lead used in the world goes into Car Batteries. Electronics makes up less than 2% of the world’s lead demand. With Lead in our circuits - we had a known, predicatable, repetitive method of connecting chips to boards with a known reliability. It only takes 3% Lead in an other wise pure Tin solder to prevent whiskers from forming .... from forming EVER.
The Tree Huggers have created vast piles of landfills of products that would otherwise have a useful life well beyond the 3-5 year for Tin Whiskers to form.
So, before you buy that $3,000 HDTV; it will NOT last as long as your 20 yr old Sony; and it has nothing to do with the reliability of Sony vs Panasonic vs LG or Samsung. It will die an early death because of the environmentalists primarily in Europe, and now in the People’s Republic of California.
There is no upside to this cluster $#%$, unless you sell high profit margin electronics and space for landfills.
Molybdenum likes to hop on charged circuitry and short it out. It’s got big enough molecules at normal temperatures to get away with this trick (after time for a build up on even gold contacts), and it’s found just everywhere ~ EVEN IN CLEAN ROOMS.
Cool.
Thanks
I was in the habit of pulling up beside idjits with Impeach Bush bumper stickers and complementing them. When they'd 'right on!' me I'd blandly say 'Yeah! I think Cheney'd make a fine president, too!' In response to their horrified look, I'd even more blandly say 'Well, if you impeach Bush, you get Cheney. Don't you liberals ever think through the consequences of any of your actions???'
I'd like to add that they used to be able to tell if the brake lights were on when the collision happened (or if the traffic signal was knocked down in an accident who had the green) because a cold filament would snap, while a hot one would stretch.

Those two bulbs were given to me.
At the moment I refuse to pay cash for one.
my buddy used them to grow garden seedlings last spring.
I was amazed at how bright they were they lit up the whole garage in this screaming bright white light.
the garage was BRIGHT but heinous looking.
So now with the 2-way spliiters i have the 2 bright ones pointing towards the middle of the garage and the two 100 watt bulbs pointing towards the walls.
They added much needed warmth and now my garage is even brighter!! :)
> “electricity cycles 60 times a sec therefore all electric lights cycle 60 times a sec.”
.
Definitely not true!
Tungsten filaments continue to ‘glow’ through about ten cycles, thus with an incandescent lamp no pulsing occurs.
.
> “Not true, actually.”
.
Unless the rectifier circuitry contains a rather substantial choke coil with an iron core, it definitely is true.
.
But there is no need to go to that level of complexity. Just choose a compact fluorescent with the right color spectrum. I got "warm white" 150-watt equivalent CF's (I "think" the real wattage is something like 50, but I'm too lazy to go check), and my garage is incredibly well lit.
Also have'em in my kitchen and dining area.....the color rendition is just like incandescents.
