I am not a fan of light bulb heated incubators.
maybe if there is a thermostat control, they might be OK,. but not great.
there might be some exceptions.
If you are hatching just barnyard run eggs, OK, then try it. but I would never try expensive eggs in one.
I do not hatch anymore. I sold all of my incubators. I had 3 that each held 2000 eggs.
and 3 that held a total combined 1600 eggs.
plus I had 8 styrofoam LG's and Hova's.
I did lots of custom hatching..
I collected guinea eggs from a couple of friends and along with my own, I hatched and sold over 300 keets each year..
good luck with your experiment and I already can foresee you getting serious about it..
