The device does not have a way to adjust temperature other than having more space beneath it by adjusting the height of the legs. It is specifically designed for the chicks to raise their head to be in contact with the heating element.If the chicks make direct contact with the heating device is it a controlled heating device on a thermostat at least because if it ever fails your chicks could get burned. My heat lamp inside 2 heatproof metal cages screwed/bolted into the cieling so no bird or substrate is ever going to touch it.
