PENTRON ECO lamps are about 2″ shorter than T8 & T12 Bi-Pin lamps. Miniature Bi-Pin bases will not install into T8 & T12 sockets. Miniature Bi-Pin bases require UL Listed 600 Volt rated sockets. Requires high frequency programmed rapid start electronic ballasts for T5s \u00a0equipped with end-of-life sensing circuit. PENTRON ECO operates at same current for uniform color and brightness between nominal 2′, 3′, 4′, and 5′ lengths. 6. \u00a0Apply thermal factor in calculations for use in exterior or unheated applications. Approximate initial lumens after 100 hours operation. The life ratings of fluorescent lamps are based on 3 hr. burning cycles under specified conditions and with ballast meeting ANSI specifications. If burning cycle is increased, there will be a corresponding increase in the average hours life. Lumen output and life rated on high frequency operation. Minimum starting temperature is a function of the ballast; consult the ballast manufacturer. There is a NEMA supported, industry issue where T2, T4, and T5 fluorescent and compact fluorescent lamps operated on high frequency ballasts may experience an abnormal end-of-life phenomenon. This end-of-life phenomenon can resultin one or both of the following: 1. Bulb wall cracking near the lamp base. 2. The lamp can overheat in the base area and possibly melt the base and socket. NEMA recommends that high frequency compact fluorescent ballasts have an end-of-life shutdown circuit which will safely and reliably shut down the system in the rare event of an abnormal end-of-life failure mode described above. The final requirements of this system are yet to be defined by ANSI. For additional information refer to NEMA papers on their WEBSITE at www.NEMA.org. SYLVANIA ECOLOGIC fluorescent lamps are designed to pass the Federal Toxic Characteristic Leaching Procedure (TCLP) criteria for classification as non-hazardous waste in most states. TCLP test results are available upon request. Lamp disposal regulations may vary, check your local & state regulations.
