U.S. Bank, the 5th largest
commercial bank in the United States,
operates 3,086 banking offices and
5,086 ATMs throughout the country.
U.S. Bank El Cajon, located
just outside the City of San Diego,
California, is a proud member of the
local community.
Since opening in 1969, the building
has been part of several renovations,
however the lighting has relatively
remained the same.
Constant lamp burnouts, ballast
failures and increasing maintenance
costs, caused U.S. Bank to look for a
better lighting alternative.

“We chose to upgrade to LED lighting since it improved the overall appearance of the bank while reducing energy and maintenance costs.”
Gregory Thorne, VP/ Environmental and Engineering Manager, U.S. Bank

The previous lighting consisted
of 139 metal halide downlight fixtures
operating at 208 watts each or 88,615
kWh annually.
With a ceiling height of 18’, these
fixtures required special equipment
brought in each time a bulb or ballast
failed. This was both cumbersome and
expensive in maintenance costs.
To meet their client’s objectives, the
team from LED Source® Los Angeles
designed and implemented an LED
lighting solution that helped support
U.S. Bank’s environmental stewardship
efforts.
For the retrofit, LED Source® chose
139 Zenaro Daylight White (4000K) 10”
Recessed LED Downlights. This fixture
provided both excellent light quality and
a work friendly color temperature. At only
40 watts each, energy consumption was
reduced to 17,041 kWh annually.
It is estimated that U.S. Bank El
Cajon will save annually $1,858* in air
conditioning, $3,324* in maintenance
costs and $10,862* in lighting energy.
Total annual savings is estimated at
$16,044* or *81% in energy savings.
In addition, an energy rebate from the
local utility of $11,815 further added to
the retrofit savings.
