Note: Lamps classified as O-type comply with ANSI standard C78.387 for containment testing and may be used in open luminaries. See lamp warning. When operated on ballasts having a sustaining voltage less than 270 Volts, lamp life may be significantly reduced. Lamps may be operated on ANSI M135 (400W) compliant ballasts. 6 20,000 average rated life based on 10 hrs/start. 30,000 average rated life based on 12 hrs/start. Color characteristics may vary somewhat from one lamp to another. Time should be allowed for lamp to stabilize in color when it is turned on for the first time or if for any reason its operating position is changed. This may require several hours of operation, with more than one start. Lamp color and output may change temporarily if the lamp is subjected to excess vibration or shock. Lamp color characteristics may change after long accumulated operating time. Use with 4000 Volt pulse-rated sockets only. Turn power off before inspection, installation, or removal. Do not use where directly exposed to water or outdoors without an enclosed fixture. Keep combustible materials away from lamp. Do not exceed rated voltage. Use in fixture rated for this product. Do not use lamp if outer glass is scratched or broken. Use only properly rated ballast.
