CFL database

I stumbled across this while looking for data on CFL Power Factors and Total
Harmonic Distortion. Some of you may find it helpful.

While this source is tooting its own horn, this does give a brief
explanation of why PF & THD are important to the utility companies.

This also touches on the same points.

http://www.gelighting.com/na/business_lighting/education_resources/literature_library/white_papers/download/123657_normal_power_factor_ballast_operation.pdf

AFAIK, there are no mandatory limits for either PF or THD in the USA. The GE
whitepaper indicates this was the case as late as 2007 when the paper was
written.

Note that the GE paper says, "Lighting has historically consumed 17% of all
electricity sold in the United States.", citing an EPA source. While this is
higher than the DOE figures I've cited, it's still difficult to see how a
switch to CFLs will save 22% or more as claimed by the proponents. I'll
stick with my figures.
