Energy Savings Add Up Quickly with LED Parking and Area Lighting

Maybe like you, I’ve recently begun switching out my compact fluorescent
 (CFL) bulbs with LED replacements in my table and ceiling fixtures. The
 energy savings aren’t huge, maybe 5 watts per lamp, and certainly not 
what I initially managed when switching from old 60 watt incandescents 
to the 13 watt CFLs. But every little bit helps, plus, the LEDs could 
last 15 or 20 years, depending on use, so I won’t have to worry about 
replacing them again for another decade or two. Hubbell Lighting

Maybe like you, I’ve recently begun switching out my compact fluorescent (CFL) bulbs with LED replacements in my table and ceiling fixtures. The energy savings aren’t huge, maybe 5 watts per lamp, and certainly not what I initially managed when switching from old 60 watt incandescents to the 13 watt CFLs. But every little bit helps, plus, the LEDs could last 15 or 20 years, depending on use, so I won’t have to worry about replacing them again for another decade or two.

While my energy savings – and, perhaps, yours as well – might be modest, after upgrading from CFL bulbs to modern LEDs, larger energy customers, especially those with numerous parking and area lights, have the potential to substantially reduce their monthly electricity bills. Many of these companies, schools and industrial facilities didn’t have an option to move away from traditional high-intensity discharge (HID) lamps, and the per-fixture difference between HIDs and LEDs can enormous.

Traditional HID lamps used in parking- and area-lighting applications, whether metal halide or high pressure sodium, can range up to 1,000 watts each, in settings requiring light levels up to 60,000 lumens (for comparison, a standard 60-watt equivalent bulb produces approximately 800 lumens). Some LED fixtures can deliver that same 60,000 lumens using only 555 watts – a savings of 450 watts per fixture. Multiply that per-fixture demand reduction across a large parking lot or campus, and you could find savings that make a truly significant impact on a facility’s energy budget.

But the cost reductions in such an upgrade project don’t’ stop with the energy savings. Just like the LED bulbs I’m buying for my living room table lamps, the light sources in today’s LED parking and area fixtures can have exceptionally long lifespans – twice as long or longer than the HID lamps they’re replacing, and even more when available dimming controls are used. Not only do owners save the cost of replacement units, they also save on the manpower and equipment needed to perform the replacement on fixtures that could be mounted 40 ft. or higher above ground.
