Summary and Implications
Temperature profiles of floor surfaces covered by heat lamps depend on lamp size and height. Heat lamps with the same power output do not necessarily produce the same temperature profiles of the heated surface. A given temperature profile of the heated area may be achieved by adjusting the height of the same heat lamp or varying the power input to the heat lamp while keeping its height. The latter will lead to energy savings.
