I put the eggs in a carton, carry them to the next room which has blacked out windows, candle, mark, return, grab more if I have more than a dozen, and repeat until they are all candled. It hasn't harmed any and I've done it daily when I had fewer than 6 eggs. I was told it takes on average 15mins for the inside of the egg to cool. I just try to finish and put them back within 10mins so they have time for the incubator to come back up to temp. If I was doing a cabinet with more than a few dozen eggs I would definitely not use light bulbs. Too much risk of them burning out or other things going wrong. There have to be better heaters than that.
