Why? Excessive heat output? Probability of reduced bulb life due to the shade reducing dissipation of the heat from that bulb? Excessive light output?

Whatever, I've been using 100-W. incandescent bulbs in four Anglepoise lamps here for many years: no problems at all - just need to remember not to touch the shade!

Al.
My reason for stating this is indeed the heat output from the 100W bulb. The early Anglepoise shades were bakelite (silver painted inside) and got quite hot enough with 60W even in good condition- a few years on with most of the silvering gone, they would stink even at 60W. A quick fix back in the day was to use a reflector bulb to protect the shade from the heat, 60W was bright enough, though I suppose you might have got away with 100W too.

Later lamps (clones?) with metal shades wouldn't have been fried by a 100W bulb, but would still have got very hot!

Nowadays, mechanical considerations apart, you could use as bright a low energy bulb as you liked.
