The resistor method would have a few troubles - keeping external breezes away would be one. Yes, the thermal inertia would be a consideration. One could do an auto calibration of the lamp by switching in a known current and measuring the output. This value would be used to scale the results. Getting a 8051 to do this would be reasonably easy. You get galvanic isolation as standard! |
