LED Lighting coming to our homes

Vinny:
Yeah, I guess I forgot to mention that they were pretty expensive.

You are correct...I should have been more specific in my post.  Kelvin is actually a temperature scale, just like Celsius and Fahrenheit are temperature scales.  But, in this case, the Kelvin scale is more of a reference to light source, rather than an exact temperature.

I do see where the LEDs are getting closer to the light color of the incandescent bulb. I have a few LED lights (tub and Christmas lights) with white LEDs and they are too blue, hopefully in a few years we will have a good LED that gives off the same quality and color light as a incandescent bulb.

With CFL's having similar life span as an incandescent bulb, the initial expense may make them inefficient...you may not save enough in energy costs to offset the cost of the bulb.  I personally don't buy them unless I can find them for under $2.00 each.  Even then, I have no idea if I'm saving enough to offset their cost when compared to incandescent.

Bonibelle:
I have to say I can take the trade off of lousy light in my kitchen because of the huge difference in the heat that incandescent bulbs produce. I have 5 high hats in the work area  and in the summer they can really heat up the kitchen!  :o So the CLFs have made a positive difference in that case,.

I believe the technology for the CLFs is developing but right now, you are right fdegree...I am spending way more for bulbs than I could ever be saving in electric.

Vinny:
Maybe not. If you have 5 - 14 Watt CFLs that are burning a total of 70 watts an hour vs 5 - 65 watt bulbs burning 325 watts an hour the savings could add up  depending on how long you use your lights along with the heat savings. The diference is 255 Watts so after 1000 hours (lights on 5 hours a day for 200 days (approx 7 months)) then there would be a significant savings IF you didn't pay a lot for the CFLs - multiply 255 Kilo watt hours (1000 x 255) by your electrical rate and that should be your savings. At $0.14/kwh x 255 kw= $35.70. I think my math is correct. ???

Theojt:
I'm with Vinny - I don't like 'em.  They're too 'cold' and they take a fair while to 'heat up' to full output.

More importantly, they contain mercury and while there are no dangers while they are intact, you have a mess on your hands if one breaks.  If you aren't aware of  mercury dangers, you should be. At higher levels, it will kill: and at low levels, it will cause irreversible brain damage, developmental problems, and lifelong illness. Our bodies retain the mercury, and repeated exposures will just accumulate more until the effects are noticed and most often irreversible.

Should a CFL break in your home, you are supposed to leave the room immediately and let it air out with the furnace or A/C off.  Clean up carefully being sure to wear gloves designed for handling such materials (Neoprene, PVC, vinyl).  Do not vacuum as this may aerate the mercury as well as contaminate your vacuum.

These blubs should not be thrown away (use double plastic baggies if you absolutley must).  Mercury is a heavy metal and can find it's way into ground water systems - they should be recycled at appropriate facilities.

Maybe these are energy efficient but they are NOT people friendly.  Read the fine print that comes with the bulb and do some research on the net.
