Lamp life
Life survival graphs are shown for statistically representative batches of lamps operated under controlled nominal conditions
with a 7 hours per start switching cycle. Declared lamp life is the median value, i.e. when 50% of lamps from a large sample
batch would have failed. Lamp life in service is affected by a number of parameters, including supply voltage variation,
switching cycle, operating position, ballast impedance tolerance, luminaire design and mechanical vibration.

The information provided is intended to be a practical guide for comparison with other lamp types. Determination of lamp
replacement schedules will depend upon relative costs of spot or group replacement and acceptable reduction in lighting
levels.

Note: Representative curves are shown for Vertical Base-Up lamp orientation unless otherwise specified. Life performance is
significantly increased in the Horizontal burning position.
