A new line of temperature controllers for heat lamps and electric infrared radiant heaters is available from Kalglo Electronics. The lower-cost Energy-Miser controllers are heavy duty, solid-state dimmers with heat sensors that automatically maintain a constant comfort level under the heat lamps for piglets. They reduce the electricity used by heat lamps, extend the life of the bulbs and eliminate the need to raise or lower the lamps depending on the age of the pigs.
