MPGs and LEDs
Much the way that MPGs and Hybrids are all the rage these
days in the auto industry, LED lamps have been the headline grabbing technology
in the lighting realm for the past few years.
With all the craze surrounding LED lamps as the lighting efficiency
savior, it is easy to get caught up in the hype and assume LED lamps are the
best solution for every application. Don’t
let the hype dim your vision.
LED lamps are a great technology that have come a very long
way and are fantastic solutions for a variety of applications; however, the
technology is still maturing and by no means should be considered the silver
bullet for all your lighting needs. A
common misconception is that an LED linear lamp is a suitable replacement for
your 4’ linear fluorescent lamps. While
that may be true someday, that day is not today.
I recently came across an article
by Jim Brodrick of the Department of Energy (DOE). In the article he explains that LED linear
replacement lamps “simply don’t perform as well as their fluorescent
counterparts…(LED linear replacement lamps) have fallen short by a significant
margin in terms of light output, system efficacy, fixture output, luminaire
efficacy, and CRI.” Bottom line, for
linear lamp replacements, 4’ fluorescent T8 (and T5) lamps are still your best
option for efficient, quality lighting.
Jim’s article makes a great point, efficiency shouldn’t
detract from performance. A Hybrid Prius
and 31 MPG Mustang are great and all for cruising and city driving, but I
wouldn’t put a trailer hitch on either.
If I need to tow something, I’m borrowing my brother’s F-250 Diesel Pickup.
LED lamps are a great technology, but don’t undermine their effectiveness
by using them without reservation. Every
lamp (and vehicle) has its purpose.
Results from DOE’s CALiPER testing program can be found here. See Rounds 9 & 10 Summary Reports.
