I have seen similar questions to this one but none of them were asked in the range of seconds only minutes.
I just finished building a incubator for chicken eggs and I am using an incandescent light bulb as source of heat. The thing is I used a pretty sensible digital termometer an the light bulb turns on, last ~20 seconds on and then turns off again. I'm worried this will cause any damage to the light bulb or the relay that acts as a switch.
The incubator works well but I dont want to replace parts every week.
