Sunbursts on the Bardavon Theater's marquee erupt with the warm shades of sunset
while white light races around the listing of featured performers.
Up on the 35-foot high blade sign the white lights within the open channel
letters etch the name "Bardavon" on the evening sky. This festival
of light is created by 3600 direct-incandescent replacement LED light bulbs
that replaced incandescent light bulbs in the marquee and blade sign. The installation
of the LED bulbs resulted in improvements in aesthetics, maintenance and energy
efficiency. "Incandescents were replaced for a number of reasons not limited
to power savings, replacement cost savings, and a new look and feel of the marquee
ingeneral," explains Jason Adams, who orchestrated the project for the
The Bardavon Theater, located in Poughkeepsie, New York, has hosted entertainment
for Hudson River Valley residents for over 130 years. Artists who have treaded
the boards include author Mark Twain, crooner Frank Sinatra and dancer Martha
Graham. A victim of suburban cineplexes, the Bardavon closed in 1975 and was
slated for demolition when local residents rescued the elegant venue. As part
of the renovation project, the Bardavon's original three-sided 1940s era marquee
and the vertical blade sign were replaced with replicas that still used incandescent
light bulbs as light sources. Later, the 3600 incandescent lamps were replaced
with energy-efficient LED bulbs from LEDtronics Inc., a manufacturer of LED
A grant from the New York State Energy Research & Development made it possible
for the nonprofit Bardavon to switch to LED-sourced lighting.
Installation of the LED lamps was a win for both the theater and the agency.
The agency fulfilled its mandate of promoting energy efficiency through innovation
and technology. And, the Bardavon lowered its operating costs because LED lamps
reduced by ninety percent the amount of energy consumed by the marquee and the
Knowledgeable about LEDs' reputed long life and major power savings, Adams
contacted LEDtronics. Following discussions with the LEDtronics' regional representative
Jeff Mizel and after testing several sample lamps, Adams purchased 3600 LEDtronics
S14-styled, Edison-screw based lamps (part number DEC-S14L-120A) in the colors
of white, yellow, orange, red and blue-green. The S14-styled LED lamps feature
25mm Edison-screw bases that enabled them to be installed into existing sockets
without requiring pricey modifications. The marquee and the blade sign typically
operate for 6 - 8 hours per show about 150 times a year, which averages about
3 hours a night over the course of a year. Due to the use of chaser circuits
all the lamps are never lit simultaneously. If they were, the signs would have
consumed 43,362Kwh per year with 11W S14 incandescent lamps. Running all the
lamps for one hour (38Kwh), multiplied by the average of 3 hours is 118Kwh multiplied
by an average cost of $0.08Kwh results in a total of around $9.44 per day or
$3445.00 per year. LED lamps drastically dropped the amount of energy consumed
from 38,000W to 4680W. The LED lamps draw 1.3W each at $0.08 kWh. The annual
electricity cost for the LED lamps is about $124.40. That adds up to an annual
savings of $3203 a year, nearly $9609 over the three-year warranty period, and
$35,233 over the typical 100,000-hour LED operating life. The annual energy
saved is 38,237Kwhs.
Besides lower energy costs, the Bardavon has benefited from the installation
of the LED lamps in another substantial way - less maintenance. LED lamps have
virtually eliminated it. Even though in the two years since the theater's signs
were reconstructed the Bardavon had only replaced about 50 of the 3600 incandescent
bulbs, the theater's maintenance staff was not looking forward to the inevitable
day when batches of incandescent bulbs would have to be changed. (The low number
of failed bulbs can be attributed to the fact that most of the incandescent
lamps were less than two years old.)
For the theater's staff replacing bulbs on the marquee was relatively easy,
requiring just a ladder; however, relamping the blade sign was more difficult.
With the top of the vertical structure 50-feet above street level, a boom lift
was needed. If the marquee and blade sign operate for an estimated 1,095 hours
a year and incandescent bulbs lasts for an average of 1000 hours, the incandescent
bulbs would, mathematically, have to be replaced about once a year. Assuming
labor for changing the bulbs is $13 an hour and there are 3600 lights that have
to be replaced, the labor costs alone amount to close to $51,246.00 for one
year if all the bulbs had to be replaced at least once during the year. Now,
add on the costs of parts, boom lift rental and operator pay. That's a bottom
line that can bring down the curtain.
When it comes to choosing lights for outside applications like the theater's
signs, it's hard to best LED lamps. Sealed assemblies make LED lamps able to
take the punishment of seasonal weather. Impervious exteriors safeguard the
electronics from water while the hardy polycarbonate globes protect the LEDs
from incidental impact and the deteriorating effect of the sun's UV rays.
Solid-state circuits withstand the electrical stress from the use of chaser
circuits. Each time an incandescent lamp is turned on the filament within the
glass globe weakens and eventually breaks. LEDs don't have filaments to break.
Their solid-state electronics enables LED bulbs to be turned on and off any
number of times without worry of burnout. What's more, LED cluster lamps continue
to provide light even if one or more individual emitters fail.
With a yearly savings of $57,271 in power savings and maintenance, the LEDs
paid for themselves in no time at all. Reducing energy and maintenance expenses
freed up resources for the theater's other restoration projects. LED lamps helped
the theater achieve its goals of reducing energy consumption, avoiding future
maintenance expenditures and updating the theater's facade.
