Spearfish Library Saves with Updated Lighting System

The Grace Balloch Memorial Library in Spearfish recently its current T8 lighting with more efficient LED lighting, reports the Black Hills Pioneer. LED lighting only uses 60 watts per fixture while producing the same light output as the previous system. The replacement cost nearly $7,000, but was eligible for a rebate from Black Hills Energy in the amount of $3,450 for upgrading to energy efficient products.

The city estimates that the project will save approximately 25,000 kilowatt-hours in their electric bill as a result of the project. The new LED lights are estimated to last for 13 years at the library based on current use. An estimate $3,000 in energy savings is predicted each year.
