Okay.
Start: 71.9 F
Finish: 73.1 F
Temperature measured with thermocouple Scotch-taped to the center of the
microscope stage, underneath an empty 96-well plate. Room thermostat set
to 70.

My light source is halogen, but it's coupled to the microscope through a
fiber optic light pipe. I know from experience that the older model scopes
with the bulb right in the base get quite warm after they've been on for a
while. I'm pretty sure my fiber optic setup can be retrofitted to most
microscopes...
