Are you thinking of still air vs forced air incubators? I've never heard of an incubator shining a light on the eggs to heat them.
No , I've noticed most small incubators being very well lit from a bulb over the eggs . Others are heated from a source behind the eggs and the warm air being circulated into the incubating area . While either can be forced air [ fan ] , I'm wondering if the dark shells are absorbing more light and running a little warmer as a result . The less efficient the incubator is at holding air temperature in , the more often the heat source would be triggered to run . If this is true , even though the eggs themselves are heating the air [ or loosing heat into the air ] , the darker ones will be running warmer than the lighter ones due to dark surfaces absorbing more light .
EDT : the only incubator I owned used a light bulb as a heat source , and it was located in the incubating area to heat the air , but wondering how that light affects the temps of the egg
I've got 4 what I suppose would be considered small incubators in that they're foam and only hold 42 eggs. They don't use a light bulb as a heat source tho. Which incubators are you referring to? I think the only one I've ever seen that uses a light bulb is the little yellow dome one and that from all the revues of it that I've read is a waste of money.
