LED Light Bulbs Made a
Long-Lasting “Star-Like” Scene at Ernst & Young
Plaza in downtown Los Angeles
The 41-story Ernst & Young
Plaza in downtown Los Angeles has a center
courtyard on the 2nd floor surrounded by retail
shops and restaurants. The courtyard is nicely
decorated with tiny light bulbs mounted on a
truss-structure above to produce a “star-like”
romantic scene at night. Replacement with
long-life, energy-efficient LED light bulbs has
eliminated the need to change burned-out
incandescent bulbs regularly, leading to an
annual saving of tens of thousands dollars for
the building owner.
Irwindale, CA, July 31, 2007 --(PR.com)--
Ernst & Young Plaza in the heart of downtown Los
Angeles is a 41-story office building with a
center courtyard on the 2nd floor surrounded by
retail shops and restaurants. Far above the
courtyard is a web-like truss-structure
ornamented with 3,400 tiny bulbs to provide a
star-like romantic scene in the evening.
Replacement of the incandescent light bulbs with
solid-state LED light bulbs from Act One
Communications has landed a significant saving
for the building owner.
Before the replacement, the 7-watt incandescent
bulb used has a typical life of 3,000 hours,
which translates into an actual usage of only
about ten months. Hence, on the average, 340
bulbs would burn out each month and needed to be
replaced, one by one, by the service crew. This
routine maintenance led to an annual cost of
tens of thousands dollars plus the need for a
heavy lifter equipment.
In 2002, the facility management company of
Ernst & Young Plaza, ABM Engineering Services,
contracted to Act One Communications, Inc. in
Irwindale, California to supply solid-state LED
light bulbs to replace those incandescent bulbs.
The new LED bulb produces the same brightness,
yet only consumes 1.3 watt power for an 80%
energy saving. In addition, the LED bulb can
last minimum 50,000 hours, meaning it can be
used for more than 13 years without replacement.
The LED bulb developed by Act One used 6 white
LED lamps made by Nichia of Japan, the original
super-bright blue LED inventor. The development
work led to a final design that matched the
color, viewing angle and brightness of the
incandescent bulb.
Since completion of the project in 2002, those
LED light bulbs have been operated in a totally
outdoor environment for more than five years.
The originally installed ones still light up
every day after sunset with no need for routine
maintenance, thus providing a truly long-lasting
“star-like” scene for diners, shoppers and
visitors at the plaza.
