Technology improvements in available lighting solutions have made it more crucial
for distributors to remain current on the latest choices for green energy-efficient
lighting.
A couple months ago, when I spoke with Will Bullock about energy-efficient
lighting, he told me that while he could chew my ear about the many benefits
of new fluorescent lighting systems over HID, his company sold and promoted
both technologies. Bullock, who until recently served as Vice President and
General Manager for Pauluhn, pointed out that there are applications where HID
is the better source. “Floodlighting and applications with ambients below
-20°C are two areas where HID is ideal. My position is that there are many industrial
applications in the U.S. that are ‘stuck’ on HID. That’s what’s installed, that’s
what staff are trained to maintain, that’s what the distributor has on the shelf,”
said Bullock.
Of course a key advantage fluorescent lighting offers over HID systems is the
ability for fluorescent to function off an occupancy sensor. “HID can take up
to 20 minutes to initially strike or to restrike in event of a power disruption.
This condition is unsafe and unproductive. In normal ambients, fluorescents
are ‘instant on’ and as such are well suited for intermittent operation in low
activity areas of an industrial plant,” explained Bullock.
On the developing LED lighting front I recently reviewed marketing materials
from LED Light Technology, LLC that compare the cost savings of the company’s
LED products with several other lighting technologies. This sales tool, labeled
“LED Light Technology-Quick Reference Guide”, was prepared by the Atlanta-based
lighting manufacturer to compare the “life cycle cost savings of owning and
operating” of LED Fixtures compared to existing lighting systems using Incandescent,
Halogen, Fluorescent, or High Intensity Discharge in the forms of Mercury Vapor,
Metal Halide, and High Pressure Sodium.
While many lighting experts have said that the “100,000-hour lamp life” rating
advertised by many LED makers is simply over the top, this particular reference
tool includes the assumption of an LED Fixture Life Cycle of 50,000 hours, which
is a far more conservative measure than the 100,000 hour rated life we’ve seen
with many other LED products.
Here are some highlighted life cycle dollar savings predicated on replacing
existing traditional lighting systems with LED Light Technology’s more energy-efficient
LED fixtures.

Obvious by its absence in this particular cost savings comparison is the newest
generation of Induction lighting, which a growing number of energy efficiency
lighting experts point to as an outstanding energy-efficient lighting solution.
But no matter how you slice it, the continual improvements in the energy efficiency
and overall performance of a growing number of available lighting products demands
that the distributor’s team works to maintain its expertise as a knowledgeable
lighting consultant to contractors and building owners alike.
