Re: [Phys-l] CFLs panned on Slashdot.



Yes, slashdot is often entertaining, but the level of science there is often absurd (though sometimes superb). I often find interesting and new information, but I simply can't treat anything I read there as unvarnished truth. As one poster put it, "As someone who teaches physics for a living, the Slashdot summary is making my eyes bleed."

The bad news: the utilities have to generate the equivalent of 28
watts (that is, 28 VA of apparent power for you EEs out there) to
light that bulb. Until they fix these issues, I'll hold on to my
incandescents and carbon arc lamps, thanks."

rubbish, the utilities already compensate for that using
capacitors. Furthermore, the CFLs's P/S technique is the same as
that of the P/Ss for computers and UPSs. If the users obeyed the
label warnings, they'd get the advertised life. However, do not
stock up on CFLs! bc predicts they'll be obsolete in a few years,
i.e. about the time the currently in use CFLs die.

bc happy w/ his recessed soffit LED lamps. And unpresciently stocked
up!! Two big boxes of CFLs

p.s. considering the incandescent technology is "post" mature (>100
years) and CFLs are nearly cutting edge comparatively, I think they
are doing VERY well. Their soon obsolescence by LED is a great
example of the acceleration of tech. innovation.
