I like the incandescent lamps in the washrooms fall, winter and spring. They help warm up the room and clear the fog from the mirror.

I really wonder how many members in the federal congress have stock or hold an interest in the companies that manufacture CFL or LED bulbs? As for me, I have been stockpiling incandescent bulbs for YEARS now...mainly to use in trouble lights or outdoor cord reel fixtures, etc. And do you know what is REALLY, REALLY STUPID about phasing out incandescent bulbs like the older 100 and 75 watt standard base type? I am looking around my family room, dining room , and kitchen as I compose this...there are a total of 45 bulbs in this 850 square foot area....guess how many are the 100 watt and 75 watt standard base type?
ONE....the rest are fluorescent, candelbra base, specialty bulbs like the ones in the fridge or microwave over the range, or 40 watt fan bulbs. The idea that replacing ONE LOUSY 100 WATT bulb with a CFL or LED in this part of my house will save energy enough to make a difference is so absurd it defies logic.....:laughing:

• Number of households in the U.S. 1960-2013 | Statistic
There are about 122.5 million households in the US. If each of those replaced one 100 watt bulb with it's lumen's equivalent CFL or LED bulb, they would each save about 80 watts per hour of use.
So:
Assuming an average daily use time of 3 hours x 80 watts = 240 watt hours saved per household per day.
240 watt-hours x 122,500,000 homes = 29,400,000,000 watt-hours (29.4 gigawatt-hours) saved per day nationwide.
At $0.10 per kWh:
$0.10 x .24 kWh = $0.024 per home per day
$0.024 x 122,500,000 homes = $2,940,000 saved electric costs per day nationwide.
It adds up.

There is some logic in replacing incandescents, especially as LED lamps continue to improve in light output (lumens per watt) and as the cost creeps downward.
For some applications, say where a light is used a fair amount and/or if it gets cycled on and off a lot, LEDs make sense. The 10 watt TCP BR30 floods I purchased for less than $10 each, consume 10 watts and put out markedly more light than the 65 watt filament bulbs they replaced. They are "soft white" and the color temperature (2700 Kelvin), appears close the replaced lamps as well.
Besides efficient use of electricity, they cast a more even light that my wife appreciates in the kitchen and over the counter. If they get there advertised 20,000 hours life, they will have paid for themselves several times over - - if I live that long :c).
CFL's pretty much suck. They are more efficient than incandescents, but they often have a warm up delay and they don't last as long when cycled often.
As to our dumb bunny government being invested in LEDs, well maybe, if they are invested heavily in China where most of the LEDs are from.

Okay, WOW! I'm sending the gum'nt a couple of LED bulbs along with a bill for 2.9 million - - I'll split the savings with them! Hope I got the math right on this. Do you think I should demand the whole 5.8 million?

I just wanted Bill to feel good about his $0.024 per day savings. He's pretty cheap ya know. Now you've ruined the idea talking about millions being split. :laughing:

Well, I have no issue with the electricity savings you illustrate....BUT: What is the REAL issue here...2.4 cents a day X 365 days=$8.76 a year....with CFL bulbs costing $4-6 each versus regular incandescent bulbs at 50 cents each....I see no real savings. Sorry....and you don't have to deal with hazardous waste disposal either.

If you paid $6.00 for a CFL and $0.50 for an incandescent, and each lasts three years:
3 years x $8.76 = $26.28 total saved. Take away the $5.50 price premium ($6 - $.50) = $20.78 total savings in three years. That's a large pizza--free--for one stinking light bulb. You want egg in your beer?

And it's not just energy savings vs bulb cost, there's also expected life span that shifts in favor towards LEDs even more. 1200 hours for incandescents vs 20,000 to 50,000 for LEDs. See:

Yeah, lighting whale oil is not easy either.
Guess they settled for candle power,
Perhaps they had eco friendly ice boxes.
