VIEWS: 24 PAGES: 24

									The list of luminaires in the
 footcandle tables in this brochure
 is by no means the complete line of
Gammalux products. If you have a
particular Gammalux luminaire in a
particular application not found
here, please call your Gammalux
sales representative or the factory
direct for the information you need.

If you wish to do your own lighting
calculations, you can download
Gammalux’s IES-formatted files of
photometry from the Gammalux
 website at www.gammalix.com.
 Or you can request to have the files
e-mailed to you. Gammalux can
 also supply the files on floppy
disks and mail them to you.

                   Partition Light Loss
                                Important


                                Warnig: Inaccuracy in testing of T5 and T5HO lamps.
                                Current IES relative photometric testing procedures
                                produce inflated luminaire efficiency
                                and light output levels.

                                Gammalux de-rates all T5 & T5HO luminaire efficiency
                                and candela values to compensate for these
                                inaccuracies. When you compare Gammalux’s luminaire
                                test results with those of other manufacturer’s, make
                                 certain that they have addressed this problem as well.

                                The inaccuracy is due to:

                                1. Standard IES testing procedures measure the light out-
                                put of fluorescent test lamps in a 25°C environment
                                for photometer calibration purposes; while

                                2. T5 and T5HO lamps obtain their 5000 lumen light
                                output rating when operated in a 35°C environment.

                                When a T5 and T5HO lamp is operated in the 25°C still
                                air condition of the current testing procedures, their light
                                output is approximately 6.25% and 7.5% less tha their
                                rated 5000 lumen output respectively. Consequently,
                                photometric reports of luminaires based on the standard
                                IES testing procedure are overstated by 6.7% when
                                using T5 lamps and by 8.1% when using T5HO lamps.
                                The lighting industry is aware of this problem (see article
                                in LD&A, the IES publication) and action has been
                                promised by the chairman of the Testing Procedures
                                Committee of the IES.

                                Gammalux has requested Indepent Testing
                                Laboratories, Inc., which provides Gammalux with all its
