All lighting has advantages. No lighting technology can "replace" another. LEDs are ideal in sheet or panel form, Fluorescents in long tube form. They are compromised as politically pushed replacements for simple incandescent bulbs - in particular to achieve omnidirectional and broad spectrum and, not least, bright lighting in the small bulb format. As if that was not enough, overall society energy savings are marginal, c.1% grid energy use based on DoE and EU (UK, Cambridge) data, and still not using life cycle comparisons. Besides, from coal plant cycle operation, little coal (the main "culprit") is saved regardless of light bulb used. http://freedomlightbulb.org/p/deception-behind-banning-light-bulbs.html The Deception behind Light Bulb Switch Arguments 13 points, referenced

Essence philosophy: about seeing the advantage of what is created as a reason for existence, rather than look for a disadvantage as a reason for destruction. Progress is welcomed - not feared. Progress brings more choice and more advantages, a progress helped - not hindered - by allowing competition against that which already exists. http://tonn.ie

It's all a matter of time and of how much incentive the bean counters in the lighting companies have, to invest in new production chains. The first CFLs I bought were just as expensive as the current LEDs. Now CFLs are getting cost competitive with archaic 1879 technology.

It is true that CFL's and LED's are not in the same playing field. LED's are definitely the Prius's of the market. Higher efficiencies at much, much higher costs. So high in fact that at this time, you cannot recover the energy savings with the cost of the bulb. With CFL's selling at Sam's Club for about $2 a pop, I can buy 20 CFL's for the cost of one comparable LED. WestLED, keep pushing, because perhaps one day, maybe we'll get there.

I just saw at a ham radio swap a booth selling LED light panels that simply had 2 strings of LEDs in opposite directions and one series resistor to limit the current, which the seller claimed was 22Ma. These were standard LED devices , 5mm with wire leads. Of course the one resistor did waste some energy, but there were no other electronic parts to fail, so the package would probably be very reliable. That could be another way to have reliable LED lighting, and probably fairly good efficiency as well. Only one current limiting resistor to waste power.

I forgot to mention that we live in Sioux Falls, South Dakota. A place with harsh winters and often hot summers as well.

In my house we use a geothermal heatpump for heating and cooling. It runs about 300% efficient on the electric power used for the compressor and fan (which uses the old A/C air ducts in the house for distribution), when compared to resistive heating with the same amount of power. Now that we have converted the electric bill to type "whole house electric heating", the monthly electric bill has averaged around $110 for the past year. RE: CFL or LED failure in demanding circumstances: I have seen stores offering "rugged" or "appliance" incandescents, and they seem to not be phased out because it is a known fact that even regular incandescents are not suitable for all circunstances (oven, microwave, refrigerator, outdoors, ceiling fan).

What a load of misconstrued generalizations about LED and CFL. For the most part CFL's and LED are not even in the same playing field. As for the engineering of LED light sources, well I test before I sell. Needless to say good quality is hard to find. And yes there are some great manufacturing companies that engineer great light sources right here in USA and Europe! CFL's, well seems most consumers hate them, they do not work well in cold temps, and the light is rarely pleasing, and even worse they don't have any life from on/off app's. Trouble with the market is everyone wants to make a zillion dollars selling junk to dumb consumers, as they are perceived by the corporate world. here we go again the end-user gets burned! OK we need good standards that inform consumers, and we need the truth about LED's, not some load of organic fertilizer spewing from this guy. I'm surprised that EE Times even published this organic fertilizer from this guy. I have tested LED lighting in app's that the market hasn't even thought of yet. They far surpass CFL's in life, operating temps, and CRI.
