General
tips:
Gas discharge lighting
is recommended for industrial lighting, for example metal halide high intensity
discharge (HID) and Linear fluorescent tubes (LFT). Compact fluorescent lamps
are not recommended here because of life of CFL varies between 6000 to 10,000
hours, while life for Linear fluorescent lights is in between 24000 to 46000
hours.1
Industrial
requirements are less downtime, peak load performance, and long life, higher
light levels because of wide spaces interiors & exteriors.
Similarly LED lighting
though very long life of 50,000 hours, but is not suitable for industrial
applications because of less light levels.
Exterior lighting in
industries or street lights, High Intensity Discharge lamps (HID) are
recommended from 150 W to 400W.
Light efficiencies of
85 to 100 lumens / Watt are common in HID & LFT categories.
Most recent light
emitting diode (LED) technology may also me used for industrial road ways with
caution, try a few poles and evaluate if satisfied HID can be replaced with
LED.

Calculator for evaluating LED in any new application, because it will
depend upon different prices (energy / labor) that vary from location to
location, so general recommendation cannot be made for LED installation
Beware!
In Linear Fluorescent
Tubes (LFT), minimum life comes in market about 24000 hours, doesn’t matter who
is the manufacturer, but still need careful consideration for any system
implementation, because in large volume application a small saving will become
big saving while a small miss will result in large losses that can be avoided.
Fake LFT are not available
in the market but the fake ballasts are very common, be careful.
Each LFT, or HID is
designed to operate with a specific ballast and fixture, so while choosing
design, we also need consideration for fixture and ballast as well.
For
energy efficiency promoting organizations, or manufacturers:
We have to reach end
users of these efficient products to realize all of the calculations, and
plans. There are intermediates (such as marketing departments, importers,
dealers, retailers, and employees) from manufacturer to the end user. “The
strength of the chain lies in its weakest link”, if there is any loose link in
between, dreams of energy efficiency or sales target will never come true. In
our 20 years of experience we have seen many loop holes, weak links in the
chain from manufacturer to the end consumer. A web shop and a company operated
outlet in major cities that sells to retail, wholesale, or industrial customer
with published prices versus quantities, monitored directly from head office is
a good, practical solution to encounter loop holes in the marketing chain. Such
shops need continuous monitoring because such shops remain under threat from
competitors hackers, in the form of insiders and outsiders alike.
Types
of Efficient Industrial Lighting
HID & LFT, categories have variety of options available to suit particular
application. Even without detailed analysis one can use LFT, HID for general
industrial application. Specific applications need particular choice from the
following category.
- Mercury vapor lamps
- Metal halide (MH) lamps
- Ceramic MH lamps
- Sodium vapor lamps
- Xenon
short-arc lamps
- Ultra-High
Performance (UHP)
Similarly it contains
various ballast types, such as:
Some lighting
manufacturer also offer useful web programmers to assist in lighting design
such as

There are also some other manufacturers of lighting products and
may have other similar or useful programmers, such as Philips and Osram.
