Sylvania CF26DT/E/IN/835/ECO Dulux® T/E Triple Amalgam T4 Compact Fluorescent Lamp; 26 Watt, 3500K, 82 CRI, 4-Pin (GX24q-3) Base, 16000 Hour Life, Phosphor Coated

Size: 0.500 Inch Dia x 5 Inch MOL

Approximate initial lumens after 100 hour 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

The life ratings of fluorescent lamps are based on 3 hour 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

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

Optimum light output for DULUX T/E IN amalgam compact fluorescent lamps occurs at approximately 35 deg C/ 95 deg F ambient temperature when the lamp is operated in the base up position; the lumen value listed refers to the optimum light output; non-amalgam compact fluorescent lamps provide atleast 90% light output from 60 - 100 deg F in the base up position, the temperature range is narrower for horizontal or base down position
