[AT] LED lights

[David Bruce]

I have replaced my most often used incandescent bulbs with CFL bulbs and 
as they expire I'll move to LED bulbs for those applications. With heavy 
use the reduced energy cost recovers the bulb cost differential more 
quickly. On the other hand those incandescent bulbs that I rarely turn 
on like the ones in the attic would never makes sense to replace in the 
same manner.

Maybe I can "leapfrog" the technology.

Single wattage bulbs that are a direct replacement for the incandescent ones we are used to are already available for less than $7 each, with an expected life of 28 years.  They are dimmable and can be intermixed with existing tungsten bulbs with no noticeable changes; that is, they operate on dimmers in exactly the same way so that you can not tell which style of bulb is in multiple bulb fixtures.  IMHO, they work better and look better than any of the CFL bulbs.  And, they last several time longer than CFL's.  Now that 3-way LED bulbs are also available, that means that there are direct "screw-in" replacements for those existing floor and table lamps that we all have in our homes.  Three-way bulbs are still a bit pricey, but they work satisfactorily and I have had no problems with them.  There is no direct conversion from !
