You can buy warm white CFL's, so no issue there. The colour temperature of CFL's is fine, if you buy the right ones.
CFL's don't give off heat? You ever try unscrewing a glowing 23W CFL bulb? I can burn my fingers on mine.
I agree with those who have stated that the incandescent bulb doesn't waste energy during the times when a house has to be heated. Heat thrown by bulbs means less heat needed from furnace or heaters. All of the ceiling fixtures in the main areas of my house are fan-and-light assemblies, so that warm air near the ceiling is circulated.
Now here's something I don't get, and if I sound like Homer Simpson that's OK, as long as you can explain...
Take two electric heaters - one from the good old days of a glowing heating coil behind a grille, and one a "high-efficiency" quartz heater. Why should a 500 watt quartz heater be giving you more heat for the wattage than a 500 watt glowing coil? How does the glowing coil "lose" a significant amount of energy that the quartz heater doesn't?
And for that matter, is replacing a standard baseboard heater with a "high efficiency" baseboard heater just a scam? What does the HE heater do that the standard heater doesn't?
Scam.... it takes the same amount of electrical energy to produce the same amount of heat whatever the medium for energy transfer. The only difference is the amount of time it takes for the process to occur. If "work" is required to perform the energy transfer (such as a fan), then the energy input is higher for the same amount of heat output as a heater without fan.
