Based on some simple assumptions, the operating costs of the LE975LED 140W light can
be compared to a 400W metal halide, with the LE975LED coming out ahead in all scenarios.
400W Metal Halide
Annual cost of energy
(24 hours per day x 7 days a week
x 52 weeks/year x $0.089 per kWh)
Annual bulb costs
$15.00 x 6 bulbs per year
Operating costs per year
This analysis does not even include the downtime associated with replacing bulbs,
restarting the metal halide light after power outage, or the lost injury time associated with
coming into contact with a hot 400W metal halide light.
