Warnings,Cautions and Operating Instructions

“WARNING:These lamps can cause serious skin burn and eye inflammation
from short wave ultraviolet radiation if outer envelope of the lamp is broken or
punctured.Do not use where people will remain for more than a few minutes
unless adequate shielding or other safety precautions are used.Certain lamps
that will automatically extinguish when the outer envelope is broken or punctured
are commercially available .” This lamp complies with FDA radiation performance
standard 21 CFR subchapter J.(USA:21CFR 1040.30 Canada:SOR/DORS/80-381)

If the outer bulb is broken or punctured,turn off at once and replace the lamp
to avoid possible injury from hazardous short wave ultraviolet radiation. Do not
scratch the outer bulb or subject it to pressure as this could cause the outer bulb
to crack or shatter.A par tial vacuum in the outer bulb may cause glass to fly if the
envelope is struck.

WARNING:The arc-tube of metal halide lamps are designed to operate under
high pressure and at temperatures up to 1000ºC and can unexpectedly rupture
due to internal or external factors such as a ballast failure or misapplication.
If the arc-tube ruptures for any reason, the outer bulb may break and pieces of
extremely hot glass might be discharged into the surrounding environment. If such
a rupture were to happen,THERE IS A RISK OF PERSONAL INJURY,PROPERTY
DAMA GE,BURNS AND FIRE.

Certain lamps that will retain all the glass particles should inner arc-tube rupture
occur are commercially available from Philips Lighting Company.

RELAMP FIXTURES AT OR BEFORE THE END OF RATED LIFE. Allowing lamps
to operate until they fail is not advised and may increase the possibility of inner
arc tube rupture.

CAUTION: TO REDUCE THE RISK OF PERSONAL INJURY, PROPERTY
DAMA GE,BURNS AND FIRE RESULTING FROM AN ARC-TUBE RUPTURE
THE FOLLOWING LAMP OPERATING INSTRUCTIONS MUST BE FOLLOWED.

Lamp Operating Instructions:

1) Turn off lamps at least once a week for at least 15 minutes in systems which
are operating on a continuous basis (24 hours/day-7days/week). FAILURE TO
TURN OFF LAMPS FOR THE MINIMUM RECOMMENDED TIME MAY
INCREASE THE POSSIBILITY OF AN INNER ARC-TUBE RUPTURE.

2) RELAMP FIXTURES AT OR BEFORE THE END OF RATED LIFE. Allowing
lamps to operate until they fail is not advised and may increase the possibility
of inner arc tube rupture.

3) Use only in an enclosed fixture capable of withstanding particles of glass having
temperatures up to 1000ºC.

4) Before lamp installation/replacement,shut power off and allow lamp and
fixture to cool to avoid electrical shock and potential burn hazards.

5) Use only auxiliary equipment meeting Philips and /or ANSI standards.
Use within voltage limits recommended by ballast manufacturer.

A.Operate lamp only within specified limits of operation.
B.For total supply load refer to ballast manufacturers electrical data.
C.All Pulse Start mogul based lamps require a socket rated to withstand

a 4000 volt pulse.

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 decomposition of the bulb glass.

8) Protect lamp base,socket and wiring against moisture, corrosive atmospheres
and excessive heat.

9) Time should be allowed for lamps to stabilize in color when turned on for the
first time. This may require several hours of operation,with more than one
start. Lamp color is also subject to change under conditions of excess vibration
or shock,and color appearance may vary between individual lamps.

10) Lamps may require 2 to 4 minutes to re-light if there is a power interruption.

11) Take care in handling and disposing of lamps. If an arc tube is broken, avoid

skin contact with any of the contents or fragments.

12) Use this lamp only in fixtures that contain a Pulse Start metal halide ballast

and are specifically designed for use with Pulse Start metal halide lamps.
