Champ® VMV LED offers new solutions
for old challenges
Lighting considerations for brand new facilities are fairly straightforward.
Engineers and Lighting Designers will typically choose the most energy efficient
or “green” solution. But what about lighting upgrades installed in older buildings
designed well before the push for energy efficient luminaires?
In the example below, a Facility Engineer contacted Cooper Crouse-Hinds to
investigate options for upgrading the lighting system in their hazardous chlorine
processing facility. The customer’s objective was simple: Improve light
levels, reduce maintenance costs, and save energy at the same time.
Existing Lighting System
The chlorine processing facility was constructed 25 years ago and still used
outdated 175W Mercury Vapor Lamps in Class I, Division 2 rated light fixtures.
The lamps frequently burned out at various intervals, and re-lamping was
difficult and timely because many of the light fixtures were located over large
tanks and other equipment.
Workers also complained that the current lighting was insufficient. The facility
was lit with (36) pendant mounted, 175W “jelly jar” light fixtures at a mounting
height of 24 feet. The fixtures were evenly spaced in the work area.
To save on installation costs, the Facility Engineer wanted any new lighting
proposals to re-use existing conduit, wiring, etc. and preferred a retrofit
solution.
Champ® VMV LED Solution
As part of the complete package from Cooper Crouse-Hinds, a complimentary
lighting layout analysis was first completed to create a model of the facility’s
existing lighting system to confirm actual light levels. It was determined that
the 175W mercury vapor luminaires provided just above 10 foot-candles of
light. The specification for the lighting upgrade required that light levels provide
an average of 15 foot-candles.
The Cooper Crouse-Hinds Lighting Layout team then replaced the existing
fixtures with the same number of new Champ LED VMV7L luminaires. Using
less than 100 watts, the VMV7L is designed for wide area illumination and for
mounting heights of greater than 12 feet. The luminaire provides light output
equivalent to many 175W metal halide (MH) fixtures while providing 60K hours
of illumination; over 6 times the life of a typical MH luminaire.
