SUMMARY
Measuring the surface temperature of a filament bulb using a thermocouple is ineffective with contact methods due to the low thermal mass of the filament. Contact with the thermocouple sensor will cause the filament to equalize in temperature with the probe, resulting in inaccurate readings. Non-contact methods, such as infrared thermometers, are recommended for accurate temperature measurement of filament bulbs.
