You can not user lamps of a higher wattage than recommended in

Then again, warm air rises. You might measure the globe temp with no
holes and the max recommended wattage, then drill the holes and turn
up the dimmer until the globe temp rises to the original value.

You also will need to measure the temperature at the socket...

I don't think so. Just aim an IR thermometer at the globe. Basic
heatflow. If it's the same before and after, the socket will be close
to the same...

I suggest you ask your local fire department what they think of that
idea.

Remember that the filament (the source of all the heat) is directly
connected to the socket with metal (great heat transfer). The socket is
going to get a lot of that heat. Cooling around the glass envelope is not
going to do much for the socket. There is a good deal of poor conductor
(air) between the filament and the glass. Your additional cooling air is
going to only come into play removing the heat that has made it post the
poor conducting air in the lamp and through the glass.

If you want to find out if it is really safe, have the UL do the
test.

Riiiight :-)
