First thing:
Compare the power output of the CHE versus the red incandescent. A 40 watt CHE will be less powerful than a 100 watt incandescent.
I use 150 watt CHEs, and they put out a TON of heat! You can melt plastic with them 3-5 inches below where they are pointed when they are on full blast, so you have to be really careful.
On top of that, CHEs seem to output heat more directed, and incandescent bulbs put out heat pretty much in all directions.
