[/B] I think the lights will pay for themselves through a significantly lower light bill. [B]
Well, according to an article by the Express News, savings would amount to $3,000 a year in electric costs.
However, the total cost for the old lights (I assume paying to hang them, remove/replace them, etc) amounted to $75,000 a year.
The new lights come with a start-up cost of $580,000 followed by annual costs of $114,000 in 2012 and $141,000 in 2013.
So in terms of dollar amounts, the new lights are far more expensive to maintain and hang compared to the old lights even though they do save $3,000 in energy costs.
