Re: A light bulb question
The link information example assumes that CFL bulb cost over $3.50 each. That being the case, payback would certainly take a long time.
Many CFL bulbs can be purchased for around $1.25 nowdays.
Do you know that GE, Sylvania and all the major lighting "manufacturer's" have these labeled and imported from China, not one made in the U.S.
Sylvania shut down their CFL factory in Danvers, Mass quite a few years ago.
Many of the 1.25 or less CFLs are very poor quality and do not even meet their LPW statements (Lumens Per Watt) that are on the box. Many never see anywhere near the 10,000 average rated life either.
The FTC and D.O.E. are getting very serious about the labeling of lighting products, and in fact the FTC fined a L.E.D. company MILLIONS of dollars as their product claims were grossly exaggerated in spec sheets and on the packaging.
The energy regulations that come into effect in 2012 are really shaking up the lighting world, and sadly consumers will have to pay a LOT more for their lighting products...
