Lighting Revived-GE Retrofits The Oakville Lighting Plant
August 2005 the Oakville Lighting Plant replaced 950 of its own
fixtures. Each fixture was replaced with 6 T8 28W High-Bay Fluorescent
Lamps. The whole retrofit took a total of 2 weeks. The process
was simple and quick, no re-wiring was required. Total cost of
this project was an estimated $250,000. Seems like a lot, but
it was estimated that the total cost of the retrofit would pay
for itself in just over two years.
year later, that estimate is now becoming a reality. The plant
has already saved close to $120,000 in energy costs savings…
the retrofit each fixture required 350 – 400 watts. After
the retrofit, that wattage was cut in half to 196 per fixture.
This resulted in energy cost savings between 44% and 51%. In dollars
that is an estimated $120,000 per year in energy cost savings.
only did Oakville’s accountant notice a difference, but
so did the employees…
Reaction Positive-Better Light
Employees noticed a big difference in their working conditions
says John Snider, Maintenance & Facilities Manager. Although
the total lumens were down slightly, the plant was experienced
in a better light. Before the retrofit, light was lost into the
ceiling. Now, light is directed downwards, illuminating the floor
Oakville Retrofit Project is a part of a Global initiative that
will involve 148 GE Industrial Manufacturing Plants and Warehouses
worldwide-110 in the Americas, 36 in Europe and 2 in Asia. GE
is expecting to cut annual lighting energy cost at each factory
by an average of 50%. Given that energy can use up to 88% of your
lighting dollar; these savings are significant for an industrial
Green GE's and Yours
are estimating upon completion of project they will save $ 12.8
million in energy costs, annually when compared to the previous
lighting.* Not only will GE will be saving energy costs they are
helping preserve the environment as the retrofit is forecasted
to use 155,700 metric tones of CO2, which equates to the ongoing
elimination of pollution from nearly 30,000 average sized cars.
In Action-Energy Cost Savings and Better Light
to each upgrade are six lamp T8 High-Bay Fluorescent Systems,
which cuts watts used by over 50%, from 465 W/fixture to 220 W/fixture
at the ballast. The T8 System Retrofit also mean better light,
the CRI (Color Rendering Index) increased to 80 from 22 CRI for
standard HPS lamps or 65 CRI to standard MH lamps.
90% of all energy emitted by tungsten filaments (including those
in halogen lamps) is infrared, or radiant heat. The way to decrease
heat from your fixtures is to use lower wattage lamps, or to use
compact fluorescent bulbs.
common types and colors of fluorescent lamps radiate an estimated
30% of their energy in the infrared range -"principally far
infrared (wavelengths beyond 5000 nm)". More information
is included in "The IESNA Lighting Handbook" by the
Illuminating Engineering Society.
meters can be purchased through any local lighting distributor.
We currently make model 217 (21475). This model can measure from
10-1000 footcandles, and carries a 1-year warranty.
