METAL HALIDE WARNINGS

WARNING: Do not use in standard incandescent sockets.

THESE INSTRUCTIONS MUST BE FOLLOWED TO AVOID POSSIBLE EARLY FAILURE OR SHATTERING OF THE LAMP. The manufacturer of this lamp will not be responsible for poor lamp performance, personal injury, property damage, burns or fire resulting from failure to follow these instructions. Metal Halide lamps are constructed of an outer bulb with an internal arc tube made of quartz. The arc tube operates at high pressure and high temperature - as high as 1100˚ C. The arc tube and outer bulb may unexpectedly rupture due to internal causes or external factors such as a system failure or misapplication. These lamps must be operated only in enclosed luminaires which comply with UL 1598 and can withstand a lamp rupture. If in doubt, contact the luminaire manufacturer. For metal halide lamps in continuously operating systems (24 hours/day, 7 days/week), turn lamps off at least once per week for a minimum of 15 minutes. Failure to comply increases the risk of rupture.

If additional safety is desired, use O-rated lamps equipped with internal arc tube shrouds and do not store combustible or flammable materials directly below the luminaire.

During Operation

1. This is a discharge lamp and requires several minutes to restart and come to full brightness after a power interruption. For total load, add auxiliary (ballast) watts to lamp watts.

2. Color variation from lamp to lamp is an inherent characteristic of metal halide lamps. It is further influenced by variation in the operating conditions and is not an indication of system or lamp failure. As lamps age, a gradual shift in color normally occurs.

If the outer envelope breaks or is punctured and lamp continues to operate, immediately turn power off and remove lamp after it has cooled.

Installing

1. Operate the lamp in the specified burning position with compatible electrical equipment. The ANSI code on the lamp must match the code on the ballast or luminaire. If in doubt, consult the luminaire manufacturer.

2. Electrically insulate any metal bulb supports in the luminaire to avoid decomposition of glass. 3. Protect lamp from direct contact with rain, sleet or snow to avoid breakage from thermal shock.

4. Install lamp firmly but not forcibly into the socket to minimize loosening due to vibration. Do not use excessive force as the glass bulb may break. Handling

5. Replace bulb if scratched, cracked or damaged.

6. Turn power off and let lamp cool before removal to avoid potential electrical shock and burns during lamp replacement.

7. Relamp at or before the end of rated life. Beyond rated life, the risk of rupture increases, light output diminishes and energy consumption may increase.

This product complies with D.H.S. Rule 21 CFR 1040 30 in effect as of date of manufacture and Canada Standard SOR/80-381.
