Based on some simple assumptions, the operating costs of the LE970LED can be compared
to a 500W quartz halogen, with the LE970LED coming out ahead in all scenarios.

For e.g., compare an LE970LED to a 500W quartz halogen on a tripod:


500W Quartz Halogen


Annual cost of energy
 (24 hours per day x 7 days a week

x 52 weeks/year x $0.089 per kWh)

$389.82 $38.98
Annual bulb costs $7.00 x 6 bulbs per year $0.00
Operating costs per year




This analysis does not even include the downtime associated with replacing bulbs or the lost
injury time associated with coming into contact with a hot 500W quartz halogen light.
