Halogen IRC dichroic lamps have many advantages over the usual standard products.
They produce the same amount of light for a 30%+ power saving.
Light output shows a whiter cleaner colour.
They last up to 67% longer with excellent light output -keep replacement costs down.
Lower load on transformers and pin contacts further reduces maintenance.
They reduce air conditioning costs.
They do cost more initially but this extra is generally a very small percentage of the power savings over the life of the lamp.
A SAMPLE CASE STUDY
A 7 day retailer with 100 lamps installed and based on three years of operation.
Today’s Costs
Replacement lamps (no labour to install) 350 @$6.00 $2100.00
Power used 57750 units @18.5c $10684.00
Total outlay $12784.00
Cost after installing NEW lamps
Replacement lamps (no labour to install) 210 @$15.00 $3150.00
Power used 40425 units @18.5c $7479.00
Total outlay $10629.00
Why would this retailer donate an extra $3205.00 to the power supplier?
Why would this retailer donate up to $840.00 to a contractor to replace the extra 140 lamps?
Would this retailer recognise the value of spending $1050 over three years to save a net $2100?
Saving based on $15.00 unit cost - $2155.00 (as above)
Saving based on $12.00 unit cost - $2520.00 (Medium volume user)
Saving based on $10.00 unit cost - $3205.00 (High volume user)

Halogen infrared
A further development that has added to halogen lamp efficacy is an infrared-reflective coating (IRC). The quartz envelope is coated with a multi-layered dichroic coating which allows visible light to be emitted while reflecting a portion of the infrared radiation back onto the filament. Such lamps are called halogen-infrared lamps, and they require less power than standard halogen lamps to produce any given light output. The efficiency increase can be as much as 40% when compared to its standard equivalent.
