PGE has announced that they are replacing the streetlamps in the county with LED's. Just finished our area, more uniform light, and just as bright as the sodium vapor or mercury vapor lamps that were in the lights.
More and more traffic signals are going to LED as well.
I also saw that New York City is starting a project to replace street lighting with LED as well.
I suspect the momentum is going to pick up on LED replacements for standard bulbs.
Based on folks I know, very few are happy with CFL's, and are looking for something better.
No the tube type floresents, another story, I have them in the garage and get plenty of light, life and low cost from them.
as for defining "end of Life" CFL are like LED's, usually defined as 50% of light output, not when the quit working. I also noticed on a package of CFL lights I had that while the package claims outrageously long life, if you read the fine print that is if they are left on 24/7. They gave life if turned on/off several times/day for a few hours at a time, and it worked out to a few years life, closer to about 2,000hrs, similar to what a halogen bulb life is.
In our kitchen CFL's were turned on/off many times/day, and on time varied from minutes to maybe an hour. Life was terrible, not anywhere as long as a halogen.
