Default Over-claimed efficiency of CFL energy saving light bulbs

Power ratio for the same light output is thus 1/3 not 1/5. This is a
66% over claim in this case.


I would tend to agree... however if you are going to argue this, you
ought to be ready for questions about how your light meter responds to
the narrower spectra of CFLs Vs incandescents.
