LEDVANCE Sylvania - Sylvania 20586 40 W 82 CRI 4100 K 3150 lm 2G11 Base Single Ended Twin Tube T5 Compact Fluorescent Lamp

DULUX 40W long compact fluorescent lamp with 4 pin base, 4100K color temperature, 82 CRI, ECOLOGIC for use on magnetic, electronic and dimming ballasts Footnotes: Rule of Thumb for Compact Fluorescent Lamps: Divide wattage of incandescent lamp by 4 to determine approximate wattage of compact fluorescent lamp that will provide similar light output.; 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.; Approximate initial lumens after 100 hours operation.; Minimum starting temperature is a function of the ballast; consult the ballast manufacturer.; 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.
