Why not just lock it or delete it?


Deletion was pondered, but wasn't really an option. The thread did get locked and put away for a little bit but eventually made its way back to the masses..

In Europe they simply banned the selling of lightbulbs of the higher wattages first, then slowly going down to the smaller ones, we now can buy high-efficiency classic lightbulbs (expensive) and energy saving lightbulbs (more expensive) and LED-lighting (even more expensive). Yes, it makes you think about how many points of light you want in your house for sure. But if this is the real answer to our ever increasing power-hunger, I don't know...

As for the US government, I would be surprised if they show for once they actually DO know what they are doing. Then I would start to worry...

The need for incandescent (filament) type light bulbs in certain uses will always be.. especially in ovens (very hot!!) and in freezers (very cold!) that LED or fluorescent lamps cannot tolerate.
The newer LED household lamps are indeed energy savers, and have a very long life.. thus repaying the cost of purchase many times over, during their life-span.
There is no practicable means to improve the efficiency of a filament lamp.. it emits 70% or more in wasted heat energy than what is given as useful light. Halogen-based lamps are more efficient yet still do not have much more than the life expectancy of "older" filament lamps.. or less of the high level of waste heat.
You might say the light bulb will "burn" for centuries to come! PDT_Armataz_01_03

"The newer LED household lamps are indeed energy savers, and have a very long life.. thus repaying the cost of purchase many times over, during their life-span. "

'PDT_Armataz_01_03' False.

In theory true, but in practical false for most of the cases. Because companies are willing to do more profit, they do not allow the full use of LED, or other "price saving" devices. Not any more.

To be sure you'll not be able to use your LED for their lifetime, they bundle LEDs with other devices, like batteries, or automatic switches, or whatever will be seen as a good idea by the consumer. Then the batteries go off after their normal lifetime, or the switch dies strangely very quickly, etc.

Because the LED and the failing device are a single piece, you have to change the expensive LED / "price saving" device.

Do you really think you'll use blinker LEDs on a car until the LEDs fail? Or LEDs on a flashlight... it's likely the motor and the fixed battery will be out before the LED, a long time before.

Marketing is made to have users think they will do a good deal, and will start saying to others that this is indeed a good deal. The truth comes when the users stop watching ads and actually use the device, i.e.... too late.

Show me a LED device with all parts repairable and available on the market when they fail, and I'll start saying that expensive LEDs repay the their cost.

Considering an average price of about $1.00 for a 60-watt incandescent lamp with 1,000 average hours of life, to a newer LED lamp with equivalent output of light.. but drawing less than 10 watts. The average 'expected' life of an LED lamp is around 30,000 hours. The cost of such a lamp? Maybe less than $20.00 USD. The savings in electric power? Upwards to $10,000.00 over its older brethren!!
And if one had been available many years ago, we would not fret about having to change a dead lamp now. Example: Phillips 60-watt LED lamp
