Shop maintains
on-site exit signs and street lighting. Existing exit signs use 15-watt
fluorescent bulbs. Street lamps are fitted with high-pressure sodium lights
that have separate lamps and pulsars. Illuminating the exit signs with
LED lighting would save $23 per sign per year. New street lamps with a
single lamp/pulsar assembly would alleviate the problem of pulsars continuing
to activate after lamps have burned out.
On-site street lamps contain a housing which requires separate lamps and
pulsars. As lamps fail, the pulsar senses the need to engage and continues
to pulse as if the lamp ignition is still required. This mode wastes energy
and shortens the pulsar's life, thus pulsars are usually changed out following
lamp change outs. A new lamp assembly is available that includes a pulsar
as part of the lamp assembly. This eliminates excess labor involved in
unnecessary pulsar changeouts.
The Public Works electrical shop changes exit light fixtures throughout
the base three times per year (two 20 watt bulbs per fixture). The cost
is excessive. FASTT Team and
the site POC have researched a LED lighting system retrofit which only
uses 1.8 watts Action on the approximately 2000 exits signs on base would
reduce kilowatt-hour charges significantly.
