Energy Saving Lighting in Industries
Industrial Efficient Lighting
This article is written to show the information which is already not published. Links are given for the works already done on the subject:
For basics introduction to lighting devices click on following links.
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.
Click on This 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
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.
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:
- Digital HID (DHID) ballasts
- Electronic ballasts
- Fluorescent lamp ballasts
Some lighting manufacturer also offer useful web programmers to assist in lighting design such as
