Outdoor LED lighting benefits from PG&E efforts, but health concerns are surfacing (MAGAZINE)
The California utility PG&E has added LED lighting to its rate schedule, but people are starting to discuss whether cool-white lighting is a great idea. BRIAN OWEN and TIM WHITAKER report.
The Electric Schedule “LS-2 - Customer-Owned Street and Highway Lighting” (see www.pge.com/tariffs/ers.shtml) lists the rates charged by PG&E for different lamp types, and is the sum of the facility charge and the energy charge. Monthly facility charges include the costs of owning, operating and maintaining the various lamp types and size. Crucially, because LS-2 now lists LEDs at a separate lamp type, it reflects the energy savings of LED compared to other lighting technologies. LS-2 is applicable to lighting installations which illuminate streets, highways, and other outdoor ways and places where the customer is a governmental agency and owns the lighting fixtures, poles and interconnecting circuits.
