The Hadco blog states this information: ” Metal Halide, Induction
lighting or LED the best lamping option for your architectural and
decorative outdoor lighting product April 23, 2008 by Al

The lighting industry has seen some dramatic changes over the past few
years. This has been pushed by rising costs such as energy, materials,
labor for installing and maintaining along with the initial cost of the
luminaries and going “Green” Today more than ever it is critical for
lighting professionals to select the correct luminaire lamp source to
meet their customer’s needs.

For this post let us….play a critical role in determining what
luminaries lamp source you choose.

Metal Halide lamps have been in service easily 25 years in architectural
and decorative outdoor lighting. …(with) The latest generation Metal
Halide lamps called ……. Pulse Start offers longer life
(15,000-20,000+ hours), start/re-strike times are reduced to 2 and 4
minutes respectively, ….(that still is not so good) With the advent of
“Title 20″ & the Federal Energy Act, Pulse Start luminaries are more
energy efficient than Probe Start. …….

Induction Lighting… has no electrodes. …….The life of Induction
lights (whether ADG Eco Lighting Products or other) is this system is an
incredible 100,000 hours so it is virtually maintenance free. Induction
lighting has been in service at least 16 years in architectural and
decorative outdoor lighting. (thanks Al you are correct and verified
these statements) The reduction in lamp maintenance helps the
environment even though it does use a minimal amount of mercury gas
(less than 20 ppm). (Induction).. also has 80+ CRI, various choices for
color temperature, no color shift, instant on, and operates in hot and
cold environments. Induction lighting can be used in many applications
such as post-top, sign, tunnel, and bridge luminaries giving it wide
range of applications. (congrats to Al for getting this info correct)

LED is perhaps the most frequently discussed lamping option available in
the lighting industry today. Although it has been around since 1969, LED
Lighting has only recently begun to find its place in the outdoor
lighting market. LED Lighting offers …..temperatures of white light
ranging from under 3,000K to greater than 6,500K. These options help to
create not just lighting effects but colored lighting effects without
special lenses though use of a DMX controller. The downfall of LED
Lighting is that the lumen output has not quite reached the levels of
its HID and Induction counterparts. While lumen levels are approaching
the 100 lm/W (also referred to as luminous efficacy) range, the
Department of Energy (DOE) does not expect it to be greater than 160
lm/W for several years. LED’s still have some inconsistent color issues
and in designs it is critical to have proper thermal management. LED’s
perform the best in colder environments and come to full brightness
instantaneously……(but) make LED Lighting extremely important to the
future of “Green” lighting (well AL it is really the opposite and
Induction is still my choice for the ULTIMATE in lighting, at ADG Eco
Lighting consultative we choose to use Induction lighting in both our
functional and decorative projects. Call Adg Eco for more information or
use some one else. Just use Induction Lighting, We know it works.
