In other words, an incandescent light bulb works much more efficientlyas a heater than it does as a source of light.

If you've replaced the bulb, it might be the wiring. The holder for the bulb sometimes is at fault. They are $40.00 at the dealer, but at a pick a part or salvage yard they are $2.00.
If a fluorescent light blinks is the light bulb bad or the ballast?
I have seen it both ways. Usually it is the bulb which is a few bucks. The ballast will cost more and could cost $15-$30 bucks depending on type. If you have another bulb that is working, swap it with the flicker light and see if the problem goes away. If the swapped bulb works, I always put the bad bulb in the fixture where the good bulb came from. If the bad bulb now works, you could have a seating problem with the bulb. If it flickers, replace it.
