Quoted from sparky672:

It's also interesting to note how this heat by-product is usually misconstrued as "waste" and that we must eliminate such wastefulness at all costs.
• For light bulbs, I prefer to spend the few extra pennies to save my retinas & brain from the flicker, UV, and blue.
• A watt is a watt. For much of the country, heat would not be considered as "waste" roughly 7-9 months of the year. For the other 3-5 months, see bullet above.

Quoted from jrpinball:

Totally agree. In winter when you need to heat your home, the more incandescent lights you run indoors, the less your heating system has to put out.

Quoted from sparky672:

Then something might be wrong with your CFL. It takes power (watts) to make that heat. If they are rated x watts, then x watts is the total power consumption, including the heat.
For an incandescent bulb, approx. 1:9 is the light:heat ratio. Ex: 100-watt bulb converts 90-watts into heat and 10-watts into light. It's a little better for the newer halogens, where a 72-watt bulb gives off the same number of lumens as the older style 100-watt bulbs.
