WARNING:

In accordance with ANSI/IESNA Standard RP-27, Display/Optic metal halide lamps are a Risk

Group 3 product.

Read and understand this warning before using this lamp!

THIS LAMP EMITS ULTRAVIOLET AND INFRARED RADIATION. ALWAYS WEAR

SUITABLE EYE PROTECTION WHEN WORKING NEAR THIS LAMP. THIS LAMP

OPERATES AT HIGH PRESSURE AND AT HIGH TEMPERATURE AND MAY

SHATTER UNEXPECTEDLY. THIS LAMP MUST BE USED IN A FIXTURE THAT

HAS A SUITABLE PROTECTIVE SHIELD AND/OR SCREEN TO PROTECT PEOPLE

AND SURROUNDINGS AGAINST THE RISK OF PERSONAL INJURY AND/OR

PROPERTY DAMAGE FROM LAMP SHATTERING AND EXPOSURE TO INFRARED

OR ULTRAVIOLET RADIATION.

RUPTURE & RADIATION (UV-IR-VISIBLE) HAZARD:

1. All Display/Optic metal halide lamps operate at high internal pressures (upwards of 500psi or

35bar possible) and may unexpectedly rupture resulting in the discharge of hot fragments

(approximately 800°C / 1472°F) of quartz and/or metal particles, as well as the release of

mercury/mercury vapor. In the event of such a rupture, there is a risk of personal injury, burns

and fire.

2. All Display/Optic metal halide lamps generate ultraviolet (UV), infrared (IR) and visible

radiation during operation. This radiation can cause permanent damage to the eyes (including

blindness) and serious injury to the skin (including burns and blistering). To avoid eye

damage, other personal injury and/or property damage, the lamp MUST be operated in a

suitable fixture.

3. A suitable fixture is one that will prevent the arc from being viewed directly while operating,

and in the event of a lamp rupture, will prevent hot (up to 800°C / 1472°F), flying fragments of

quartz and/or metal from escaping into the area.

4. To minimize the risk of a lamp rupture, replace the lamp at or before the end of rated life (see

OSRAM SYLVANIA product catalog for rated life) or when the lamp shows signs of

blackening.

5. The discharge vessel of Display/Optic metal halide lamps is constructed of quartz glass that is

filled with a quantity of mercury, elemental metals and/or rare earth elements. These lamps

are not

at positive pressure when cold (not operating, at room temperature).
