Homemade Incubators?

The bulbs are ceramic reptile type. 40 watt. The tin cans buffer the heat during the on and off cycles. I was getting small temp spikes near the bulbs and that was just enough to even it out.

I have never done it but I'd heard of moving the thermostat closer to the heat source to minimize spiking. Makes them cycle faster.
