Dark Sky Lighting Ordinance Approved

Reno, Nevada's Lyon County Commission passed an ordinance to establish criteria for outdoor lighting within the county. The Lyon County planning director said the ordinance regulates outdoor lighting for commercial and industrial facilities for nonresidential uses.

The new ordinance requires that all outdoor light fixtures must be fully or partially shielded, depending on the fixture lamp type. It lists requirements for shielding based upon each type of fixtures. It also states that mercury vapor fixtures installed prior to the effective date of the ordinance shall be replaced or equipped with a filter no later than Dec. 21, 2011.
