I wanted to be able to control the heat without movimg the heat source, I found a nifty dimmer switch at lowes for $15.00
The heat lamp just plugs into the dimmer plug, the dimmer also has a slide control to adjust the lamp which controls the heat.
I use a 250W red heat lamp which when just plugged in would be above 117 degrees way to hot for indoors.
A thermometer inside the brooder shows when I have the desired temp.
I also put half flat glass beads "like for an aquarium" in the waterer to protect the fuzzy butts from drowning
