High-performance, long life, environmentally-responsible lamps. These high-performance lamps are ideal for applications where high-lumens, long life and high-CRI are required. Approximate initial lumens are for 800 mA operation. For 1000 mA operation, lumens are approximately 10% higher and watts approximately 15% higher. Econ-o-watt lamps are only recommended for use on high-power factor lead, indoor ballasts that meet ANSI standards. The lamps are not recommended for use in drafty areas or locations where the ambient temperature is less than 60 deg F, except as noted. Also they should not be operated on low power factor ballasts, reduced light or reduced current ballasts, dimming ballasts or emergency system inverter ballasts.
