SYLVANIA MP70/U/MED | METALARC® PRO-TECH® 70W Pulse Start Metal Halide Lamp

The Sylvania METALARC® PRO-TECH® (MP70/U/MED) is a commercial-grade, high-performance **70W pulse start metal halide lamp** engineered for retail displays, warehouse pathways, and demanding security perimeters. Outfitted with a standard **E26 Medium Screw base** and an **E17 bulb shape**, this high-intensity discharge (HID) bulb produces a welcoming **2900K Warm White** color temperature. Featuring Sylvania's signature open-fixture rating, the internal arc tube is encased in a specialized **PRO-TECH® protective shroud** engineered to safely contain non-passive failures. Operating on an **ANSI M98/O specification**, this pulse-start model offers rapid restrike phases, minimal color drift, and an impressive **10,000 to 15,000-hour rated lifespan** depending on its final mounting orientation.

PRO-TECH® Containment Shroud and Advanced Pulse Start Performance

Sylvania METALARC® PRO-TECH® lamps eliminate the strict enclosure barriers traditionally associated with standard metal halide architectures. The integrated quartz containment shroud shields the system from containment breaches, making it fully approved for **open or enclosed fixtures**. Utilizing high-performance pulse-start ignition technology, this lamp delivers enhanced lumen maintenance curves, faster starting sequences, and minimal color shifting over its operational cycle compared to older probe-start alternatives. Engineered with a **universal burn position**, it offers complete installation flexibility across a wide range of directional high-bay and low-bay tracking heads.

• Open Fixture Rated Safety: Shrouded arc-tube design allows the lamp to run safely in open-rated luminaires, eliminating the need for costly heavy protective glass covers.
• Flexible Burn Configuration: Achieves an extended **15,000-hour rated life** when mounted vertically, and a dependable **10,000-hour life** in horizontal orientations.
• Warm, Welcoming Illumination: Emits a comfortable 2900K warm white spectrum with a 75 CRI rating, ideal for neutralizing the sterile feel of commercial warehouses and retail aisles.
• Compact E17 Envelope Profile: Easily retrofits into standard compact architectural downlights, floodlights, and pathway structures.

System Integration & Socket Safety Guidelines

• Pulse Voltage Controls: This high-intensity pulse-start lamp must be paired exclusively with specialized **4,000V (4kV) pulse-rated sockets**. Standard low-voltage residential sockets cannot safely clear the ignition pulses generated by the ballast.
• Ballast Synchronization: Must operate natively on an industry-standard, thermally protected ballast rated precisely for **ANSI M98/O** network lines. Connecting to unsupported probe-start ballasts will cause premature ignition failure, extreme thermal variations, and rapid arc-tube decay.
• Fixture Flexibility: Due to the PRO-TECH® dual-containment infrastructure, this lamp can be safely specified for open-reflector setups as well as sealed, weather-rated outdoor enclosures.

Recommended Industrial & Commercial Applications

• Commercial Track and Downlighting: Perfect for high-ceiling retail environments, open public lobbies, and municipal buildings requiring long-lasting, focused warm light.
• Warehouse & Storage Aisles: Provides comfortable, shadow-reducing lighting over loading docks, distribution facilities, and deep industrial racking.
• Area and Security Floodlights: Highly suited for outdoor perimeter wall packs, pedestrian pathway poles, and exterior storefront illumination when mounted in weather-proof enclosures.
