The particular error of banning 100W+ ordinary bulbs is that bright CFLs or LEDs are comparatively difficult and expensive to make,
and the high wattage heat effect is not necessarily wasted (room heat substantially rises towards the ceiling by convection, and spreads downwards from there).

Banning frosted lights smacks of particularly unwarranted EU pettiness, for any marginal savings involved.
Clear lights (including halogens) have a strong glare – hence the overwhelming popularity of frosted lights for ceiling use.

Another problem is that small bright CFLs and LEDs are difficult to make, so that candle/golfball lights are bulkier and may not fit some lamps.

Supposed savings don’t hold up for many reasons:
Just a few examples here: CFL Lifespan is lab tested in 3 hour cycles. That does not correspond to real life usage and numerous tests have shown real life type on-off switching reducing lifespan. Leaving lights on of course also uses up energy, as does the switch-on power surge with CFLs
Also, CFLs get dimmer with age, effectively reducing lifespan

Power factor: Few people know that CFLs typically have a power factor of 0.5 – that means that power stations use up twice as much power than what the CFL rating shows. This has to do with current and voltage phase differences set up when CFLs are used.
Although consumers do not see this on their meters, they will of course have to pay for it on their bills.

Emissions?
Does a light bulb give out any gases?
Power stations might not either:
Why should emission-free households be denied the use of lighting they obviously want to use?
Low emission households already dominate some regions, and will increase everywhere, since emissions will be reduced anyway through the planned use of coal/gas processing technology and/or energy substitution.
