Your Total Savings =
Energy Savings Formula:
life expectancy of bulb x energy costs per Kwh x wattage + cost of bulb(s)
1000
= total cost of ownership


1 EFO = 56 Halogen MR-16s Bulbs
(1 EFO replaces 8 MR-16 spots and lasts 7x as long = 56)


Examples:
Traditional Bulb, 50W MR-16:
(2000 hours x $0.10 per Kwh x 50W + $5.00) x 56 bulbs
1000
= $840


EFO:
(14,000 hours x $0.10 per Kwh x 70W + $50.00) x 1 bulb
1000
= $148

Difference:
$692 in savings over the life of the bulb


Assumptions:*
14,000 hours - the typical life expectancy of an EFO bulb.
$50.00 - the average price of a single EFO bulb.
750 hours - the typical life expectancy of an incandescent bulb.
$0.75 - the average price of a single incandescent bulb.
2,000 hours the typical life expectancy of a halogen bulb.
$5.00 - the average price of a single halogen bulb.
6,000 hours the typical life expectancy of a CMH bulb.
$40.00 - the average price of a single CMH bulb.


$0.10 - the average cost of energy per kilowatt hour (Kwh).

*can vary depending on region and type of bulb used
