Based on some simple assumptions, the operating costs of the TLS-100LED  6.6W X 10 string light can
be compared to a 100W X 10 incandescent, with the TLS-100LED coming out ahead in all scenarios.


100W X 10 Incandescent


Annual cost of energy
 (24 hours per day x 7 days a week
x 52 weeks/year x $0.089 per kWh)
$770.96 $51.46
Annual bulb costs $2.00 x 60 bulbs per year $0.00
Operating costs per year




This analysis does not even include the downtime associated with replacing bulbs.
