I don't like fluorescent light bulbs.From now on when I go to the food
store,I am going to start stocking up on good old G.E.Real Incandescent
Light Bulbs,the 60 Watters.I am going to clean off the top shelves in
the closets in my house and stack em up in cardboard boxes.When fed govt
starts shoving fluorescent light bulbs (so-called light bulbs) down
everybodys throats,I will still be wasteing my electricity that I pay
for on my good old G.E.Real Incandscent 60 WATT LIGHT BULBS.
cuhulin,the Electricity Waster dude.Waste Mo Electricity,you can't take
it with you


In celebration of Earth Day my local grocery store had GE CFL's on
sale for a buck a piece. Couldn't resist the opportunity so I swapped
out most of the bulbs. What a difference - because they are so much
more efficient they consume 1/4 the energy for an equivalent amount of
light from an incandescent bulb. The color temperature is very close
to incandescent too.

And for SWL's concerned about noise, the only time I pick up any noise
from one is to move the radio to within 5 inches of the light.

Did you know that even though CFL's contain a very small amount of
mercury that they actually release less mercury into the atmosphere
than an incandescent. That is possible because much of our power
comes from burned coal which releases large amounts of mercury into
the air. Indeed if you were to break all of the mercury CFL bulbs the
total amount of mercury released including the amount of mercury used
in power generation would be far less than that released by
incandescent.


You can always have a bulb re-cycling program to collect the mercury.

The CFL's I have seen do not have a incandescent bulb spectrum but like
most florescent bulbs tint toward blue. It would cost more money for the
inside bulb coating and also reduce the efficiency of the bulb for a CFL
to generate a redder spectrum.

What did you pay for the bulbs?

Another question is how did you determine that they only disturb the
radio from 5 inches away? The problem with this technology is that the
power spectrum they broadcast is diverse with more power on some
frequencies. You would need a spectrum analyzer to determine this with
any certainty.
