A LOT CAN HAPPEN IN JUST 20 YEARS: WHERE
EXTERIOR LIGHTING WAS THEN & WHERE IT IS NOW
To give you an idea of what the new generation of LED-based
exterior lighting can mean to your projects, think back to
what your life was like in 1990. That was over 20 years ago. Your cell
phone, if you had one, was so big and heavy, carrying it probably
qualified as an exercise program. Businesses and governments threw tons
of dollars at something known ominously as Y2K, which was supposed to
throw us back into the Stone Age. (It didn’t, but they still
spent
billions on new IT systems). The washing machine and dryer you bought
that year? They’re probably long gone…or chugging
along on their last
legs, costing more in energy alone than it would take to replace them
with newer models.
Back then; the lighting industry
was dominated by high intensity discharge sources like metal halide and
high pressure sodium. Those lights were based on systems that often
required the so-called 20,000-hour lamps in a standard exterior
scenario to be replaced in masses as early as 8,000 hours after they
were installed. Which means scheduled bulb replacements would have
started just two years after installation
Think about what that really means. While businesses and government
agencies have always been told that they should do group
“re-lamping” at the 8,000-hour mark, the fiscal
reality is that hardly
any of them ever do. They usually do spot re-lamping instead. That gets
pretty costly year in and year out when you tally up the maintenance
costs of hiring a crew, getting a lift truck out to the facility, and
buying and installing the replacement lamps. It also results in poor
lighting when lights go out, creating safety and image issues as well.
LED-based exterior lighting systems,
on the other hand, not only can be designed to last up to 100,000 hours
– they actually can remain in service that long, almost
maintenance-free. That means they can last up to 20 years. By the time
you’d need to replace your LED luminaire,
who knows where technology will have taken us? Maybe we’ll all
finally
be carrying around the portable quantum generators that were predicted.
For businesses and governments looking to make smart infrastructure
investments, LED-based exterior systems offer greater reliability, a
wider range of optics to choose from, and can now last near
maintenance-free for more than a decade. It’s one of the smartest
fiscal moves they can make. Much smarter than our old washers and
dryers that have needed to be replaced in the past 20 years.
