1)Rated average life is the lifeobtained, on the average, fromlar gerepresentative groups of lamps in laboratory tests under controlled conditions at 10 or more operatinghour s perstar t.
Itis based on survival of at least 50% of the lamps and allows forindividual lamps or groups of lamps to vary considerably from the average.
2)Measured at 100 hours of life in vertical operating position.
3)Approximate meanlumen output at 40% of lamp rated average life. Measured in vertical operating position.
4)Approximate colortemperature in Kelvin degrees.

WARNINGS,CAUTIONSANDOPERATINGINSTRUCTIONS FOR SAFETY
LIFEGUARDMETALHALIDE LAMPS (OPEN OR ENCLOSED FIXTURES)
TWARNING:Thislamp should self extinguish within 15 minutes after outer envelope
isbroken or punctured. If such damage occurs, turn off and remove lamp to avoid
possibleinjury from hazardous shor twaveultr avioletradiation.”This lamp complies with
FDAradiation performance standard 21 CFR subchapter J. (USA:21CFR 1040.30
Canada:SOR/DORS/80-381)This lamp should not be used on dimmers and is not
warrantedif used on dimming systems.
Ifthe outer bulb is broken or punctured,turn off at once and replace
thelamp to avoid possible injury from hazardous short wave ultraviolet
radiation.Do not scratch the outer bulb or subject it to pressureas this
couldcause the outer bulb to crack or shatter.A partial vacuum in the
outerbulb may cause glass to fly if the envelope is struck.
WARNING:Thearc-tube of metal halide lamps are designed to operate under high
pressureand at temperatures up to 1000ºC and can unexpectedly rupture due to internal
orexternal factors such as a ballast failure or misapplication. If the arc-tube ruptures for
anyreason, the outer bulb may break and pieces of extremely hot glass might be discharged
intothe surrounding environment. If such a rupture were to happen, THERE IS A RISK
OFPERSONAL INJURY,PROPERTY DAMAGE,BURNSAND FIRE.
Certainlamps that will retain all the glass particles should inner arc-tube
ruptureoccur are commercially available from PhilipsLighting Company.
RELAMPFIXTURES ATOR BEFORE THE END OF RATEDLIFE.
Allowinglamps to operate until they fail is not advised and may increase the possibility
ofinner arc tube rupture.
CAUTION:TOREDUCETHE RISK OF PERSONAL INJURY,PROPERTY DAMAGE,
BURNSAND FIRE RESULTING FROMAN ARC-TUBE RUPTURE THE FOLLOWING
LAMPOPERATING INSTRUCTIONS MUST BE FOLLOWED:
LAMPOPERATING INSTRUCTIONS:
1.Turnoff lamps at least once a week for at least 15 minutes in systems which are operating on a
continuousbasis (24 hours/day-7days/week). FAILURETOTURN OFF LAMPS FOR THE MINIMUM
RECOMMENDEDTIME MAYINCREASE THE POSSIBILITY OFAN INNER ARC-TUBE RUPTURE.
2.RELAMP FIXTURES ATOR BEFORE THE END OF RATEDLIFE. Allowing lamps to operate until they
failis not advised and may increase the possibility of inner arc-tube rupture.
3.If operated other than vertical ± 15º,use only in an enclosed fixture capable of
withstandingparticles of glass having temperatures up to 1000º C.
4.Before lamp installation/replacement,shut power off and allow lamp and fixture to cool to avoid
electricalshock and potential burn hazards.
5.Use only auxiliary equipment meeting Philips and/or ANSI standards.Use within voltage limits
recommendedby ballast manufacturer.
A.Operate lamp only within specified limits of operation.
B.For total supply load refer to ballast manufacturers electrical data.
6.Periodically inspect the outer envelope.Replace any lamps that show scratches, cracks or damage.
7.If a lamp bulb support is used, be sure to insulate the support electrically to avoid possible
decompositionof the bulb glass.
8.Protect lamp base, socket and wiring against moisture,cor rosiveatmospheres and excessive heat.
9.Time should be allowed for lamps to stabilize in color when turned on for the first time.This may
requireseveral hours of operation, with more than one start. Lamp color is also subject to change
underconditionsof excess vibration or shock and color appearancemay vary between individual lamps.
10.Lamps may require 10 to 20 minutes to re-light if there is a power interruption.
11.Takecare in handling and disposing of lamps. If an arc tube is broken, avoidskin contact with any of
thecontents or fragments.
12.Do not use this lamp:
A.In a fixture that contains a Pulse Start metal halide ballast.
B.In a fixture that is specifically designed for use with Pulse Start metal halide lamps.
Operationof these lamps on Pulse Start Metal Halide systems may increase the chance
ofan outer bulb rupture and pieces of extremely hot glass might be discharged into the
surroundingenvironment. If such a rupture were to happen,THERE IS A RISKOF
PERSONALINJURY,PROPERTY DAMAGE,BURNSAND FIRE.
