[AT] LED lights

[charlie hill]

I refuse to use the CFL bulbs but would have no problem with the LED's and 
will switch to them
as needed.  However, I do have one question.  When all of the incandescent 
bulbs are gone what
are we going to use to keep chicks warm in the brooder, dogs warm in the dog 
house on cold nights
and the water pump from freezing up?  Electric resistance heaters???????

My experience is that the total cost (original purchase plus cost of power) 
is already low enough to make the investment in LED for lighting worthwhile. 
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 !
the old power consumption scheme we are used to (wattage) into the Lumens 
method that is being used for LED's, but a conversion for the old and new 
methods is printed on the package of each LED bulb you buy, and a few 
minutes study in the store will let you figure out whether a particular bulb 
is going to be "the right size" for your particular application.
