Reducing Heat Load Energy efficient lighting is very important in cooled and refrigerated areas because of the reduced heat load which means that less energy is required to condition a space. This can reduce the amount of energy used by heating, ventilation and air conditioning (HVAC) systems. The lighting technology used in air conditioned or refrigerated areas should be reviewed across the site. LEDs are particularly effective in low temperature areas

Voltage Reduction Savings of up to 30% are quoted by manufacturers. A more conservative saving is 8% Voltage reduction is suited to electronic ballasts and will not work on magnetic ballasts and compact fluorescents Typical costs of voltage reduction units is $1,000 installed
