The DOE did not factor in the A/C cost to remove the additional heat generated by CFL infrared and convection losses for hot climates. The loss has double impact there. For colder climates, the loss of the bulb heats the house and therefore reduces the heating costs so a filament bulb as close to the humans as possible may make the most sense for sustainability. | |

This may be true, but given the fact that when we talk about sustainability we should think about pollution too, In this case LED bulbs would be preferable as their disposal do not contribute as much with harmful chemicals as the CFL bulbs do. | |
