The next big savings is on savings from cooling. In a freezer,
every watt of light output has to be removed to maintain the
temperature. A savings of 823 BTUs per fixture translates into
approximately 3 tons of cooling capacity. More efficient?
Definitely!
Lower replacement costs and lower recycling costs generate
additional cost savings. The fluorescent high bays have a
longer expected life than the metal halide, because, Mr. Stoltzfus is
using extended-life lamps rated at 30,000 hours. Mr. Stoltzfus
projects replacing the lamps only every 5 or 6 years. This results
in less maintenance time. When replacement time does arrive, the 6
fluorescent lamps cost about half the cost of a single metal halide
lamp. Further, the fluorescent lamps cost less to recycle than the
MH lamps.
Besides all of this, the fluorescent lamps shine more
brightly. The fluorescent lamps have less lumen depreciation over time
than the MH lamps. The fluorescent light output depreciates only
about 5% versus up to 25% for MH lamps. Brighter light yields
better ability to pick orders, thus increasing operational
efficiency. On top of this, the fluorescents produce a color
rendering index of 85 versus only 65 for the MH lamps. Another
benefit is the instant start of the fluorescents versus the delay with
metal halide lamps, even pulse start MH take longer to start.
Mr. Stoltzfus said that he expects to get better lighting
for less wattage with the ENF6. He is so pleased with their
performance that he plans to replace the lights in his other freezer
facilities with 60 more ENF6 fixtures. He agreed that it really is
a win-win situation.
