Sylvania 64319 Metal Halide Lamp
The Sylvania 64319 is a 175 watt Metalarc Pulse Start metal halide lamp designed for commercial and industrial lighting installations. It operates on an E39 mogul base and produces a 4500K color temperature suitable for warehouses, retail spaces and outdoor area lighting. The clear BT28 bulb delivers 14400 lumens with a color rendering index of 65. This lamp is rated for universal burning position and enclosed fixtures only.
Thermal and Power Characteristics
The lamp consumes 175 watts during normal operation and requires a compatible ANSI M152/E ballast to regulate current. Metal halide technology generates significant heat, so the fixture must be enclosed and rated for the lamp's thermal output. The 4500K color temperature remains stable over the rated 12000 hour life span with reduced color shift compared to standard probe-start designs. The pulse start system provides reliable ignition without a starting electrode.
Sustained Operation Behavior
Under continuous use the lamp maintains consistent lumen output through its 12000 hour rated life when operated in an enclosed fixture with the correct ballast. The pulse start technology reduces warm-up time and improves lumen maintenance over extended burning cycles compared to older probe-start metal halide lamps. Universal burn positioning allows flexible fixture aiming without affecting performance or lamp life. Enclosed fixture rating is mandatory for safe operation.

Questions about this item
How do I install the SYLVANIA 64319 175W metal halide bulb and which step is often missed?
Screw the E39 base firmly into a compatible mogul socket inside an enclosed fixture rated for ANSI M152/E pulse-start operation; the step often missed is confirming the fixture is fully enclosed, as this lamp requires an enclosed fixture for safe operation.
What maintenance or replacement will the SYLVANIA 64319 175W metal halide bulb need over time?
Plan to replace the lamp after approximately 12000 hours of operation; metal halide output and colour stability decline gradually, so scheduled group relamping maintains consistent 14400 lumen performance and 4500K colour temperature.
What is the first limitation that appears when the SYLVANIA 64319 175W metal halide bulb runs continuously for long periods?
The 12000-hour rated life is the primary limit; extended continuous operation accelerates lumen depreciation and colour shift beyond the CRI 65 baseline, requiring earlier replacement to maintain light quality.
