Factor in the energy cost of making CFL/LED bulbs (including the additional electronics and mining the required material and all the shipping it requires) and the energy costs of dealing with the toxic waste they contains, and now this doesn't seem as much like a sensible move.

When you compare retail prices and actual lifetime you notice that the new bulbs are significantly more expensive than the now banned traditional ones while having overrated life expectancies and now you understand that the manufacturers are getting more money and faster, suddenly this overpriced incompetence has a feel of greenwashing followed by an aftertaste of lobbying

I know of no study that agrees with your conclusion. Among others, Umweltbundesamt (German government), BUND (German NGO, parts of Friends of the Earth), Empa (Swiss Federal Laboratories for Materials Science) have come out in favour of CFL bulbs.

I can't believe we're still having this discussion in 2014. To add to cygx's point, a quick break even sum:

A 60W equivalent costs around $1.50, and using ~12W of energy. Even if we use the lowest electricity cost for the US ($0.08/kWh), and assume the incandescent bulb was free:

cost of bulb / power difference * cost per Wh = break even time

1.50 / (60-12) * (0.08 / 1000) = 390 hours

So you only need to use a bulb for 390h to recover the total purchase cost. You can argue all you want about lifetimes, equivalence etc, but these are not marginal figures, especially when you factor in that real EU electricity prices tend to be 2-5x the figures I used-- with German or Danish electricity you'll have pay back times well under 100h.

Those like you and ekianjo make a good case for regulation. The EU banned incandescents, the world did not implode.

Do you have any evidence to back up your assertion that CFLs and LEDs are more harmful to manufacture and recycle than incandescents?
This. I'm glad there are still sensible people out there on HN.
