Up Time Magazine - February/March 2009 - (Page 13) watt saved is a penny earned. New technology includes three main types of lighting. The first are new high output fluorescent tubes. Plants and manufacturers are now replacing the old low bay or high bay High Intensity Discharge (HID) fixtures (such as Metal Halide, High Pressure Sodium or Mercury Vapor) with new high output T-5 fluorescent fixtures. A typical 400watt Metal Halide fixture, which consumes approximately 450 watts, can now be replaced with a new T-5 fluorescent fixture on a one-toone replacement basis to reduce energy consumption by nearly half. So, in addition to saving 50% the next time you turn on the switch, you also get superior light quality, quantity and light distribution. The other advantage of fluorescent over HID is that the lights can be turned on instantly allowing for a greater opportunity to switch lights off during the day. One of our customers in North Carolina even added a lighting control system to their T-5 lighting project and scheduled lights off and on during the day during breaks and lunch time. This scheduled switching serves as notice to the workers that it is time for breaks and lunch. Reasonable lighting is always maintained in isle ways for safety and security. Lamp life remains comparable between HID and T-5’s. The simple payback, including labor and material, for this improvement is approximately 2 years. Tax credits may also be available through the IRS for projects that reduce lighting costs by more than 50%, which is a feasible goal with this and other lighting techniques. A direct tax credit of $0.60/sq.ft. may be obtained after an engineering professional prepares a report and an accountant files the proper government paper work. There is an excellent overview of T-5 lighting from the Lighting Research Center at this link: http://www.lrc.rpi.edu/programs/nlpip/lightingAnswers/lat5/abstract.asp There has also been recent improvement in LED lighting. It is safe to say that there is an LED retrofit bulb available for every type of incandescent lamp application. The light levels are comparable to their incandescent counterpart and the color of the LED’s is now a crisp white light, unlike the early prototypes that appeared greenish or bluish. Compact fluorescent lamps are also very attractive replacements for incandescent bulbs and are available in all styles and wattages. The payback on both compact fluorescent lamps and LED’s is very good. 0.625” 1.00” 1.50” T5 T8 T12 Figure 2 - T-5 Lamps are a smaller diameter and slightly shorter than T-8’s and T-12’s. The Lighting Research Center has an excellent report on LED lighting in a downloadable PDF file available from: http://www.lrc. rpi.edu/programs/nlpip/publicationdetails. asp?id=885&type=2 The other dramatic improvement in lighting technology worth investigating is outdoor lighting. Parking lot and flood light fixtures are now using both Induction Florescent lamps and LED technology very effectively. An induction fluorescent lamp is the same concept as normal fluorescent, with the ballast on the outside of a sealed fluorescent tube. The advantage is a much longer life of approximately 100,000 hours with an increase in efficiency Our Students Call It CSI for Engineers. We call it “Practical Plant Failure Analysis” It’s a reasonably-priced practical seminar with hundreds of hands-on examples designed for plant people and engineers. You’ll work with gears, bearings, shafts, belts, fasteners, seals, and a selection of corrosion examples. With the hands-on analyses, you’ll learn how and why they fail – and how to diagnose the multiple causes. e public session is three days long and is held in Syracuse,NY in November. Private sessions range from two to four days and can be held at your site. From the Reliability Professionals who “wrote the book on logical and practical plant failure analysis”.
