A correction: Lumens weren't introduced for CFLs. They have been on
incandescent bulb packages for a decade or more. Granted, they are more
important for CFLs and LEDs, as the watts tell you nothing about the amount of
light across technologies, but they are not recent. Remember, you are
I listed as well and agree with your assessment, we have a local show here like
that and the host comes across very professional and unbiased, this guy sounded
very biased and unprofessional.

ago when I was in the (then required) 7th-grade shop course, we spent the
beginning of each class going around the room converting fractions into
Just as a small technical point. There are no such things as degrees Kelvin.
They are just kelvins (and lower case only).

So much the better! I haven't bought incandescent bulbs in about ten
years (CFLs last so much longer), so I didn't know that the lumen
information had been included on those packages as well. Also, the
packages show the light warmth in degrees Kelvin. That is very useful
as my eyes want the
