"All but that last Sawzaw, 42 watts is over 40 and you leave it long enough, you will get what the electrical field folk call by the technical term: "crispy critters".

I see your point but the CFs put out more light and less heat because they are more efficient.

They convert mote of the electricity to light and less into heat.

Therefore a 150 watt equivalent CF does not get as hot as a 40W incandescent bulb.

At least I am pretty sure of it. I know that when I unscrew a 40 Incandescent while it is lit, it is so damned hot I have to use a towel. But with the CFs I can use ny bare hands.

You could test this yourself just using your hands.

I even have some 200 watters that I can unscrew with my bare hands.
