Is The City of Calgary retrofitting with single or dual arc tube lamps?
The City is using single “arc tube” lamps. We did look at the twin tube lamps but their use was not determined to be cost effective. The dual arc tube lamps have a rated life expectancy that is 67% longer than the single arc tube lamp, but it is about 3 times more costly. The City is not pursuing this option at this time.
