Product Overview

The Sylvania 69137 HBO 3500 W/HK is a 3500W mercury short-arc high-pressure lamp in the Sylvania HBO series — a direct current arc source producing continuous UV and visible spectrum output. HBO lamps are the primary light source for UV fluorescence microscopy, photolithography, cinema projection requiring UV-rich output, and UV exposure/curing systems. Burn position: Anode Up Burn Position — incorrect orientation causes arc instability and reduces lamp life. Operating at 55V DC requires a dedicated constant-current DC power supply rated for Type: DC.

Applications

• Fluorescence microscopy – Primary UV source for UV-excited fluorescence in research-grade and clinical microscopes.
• Photolithography and UV exposure – UV-rich output for photoresist exposure in semiconductor and PCB manufacturing.
• Cinema and large-venue lighting – High-intensity mercury arc for cinema projection and large-venue searchlight systems.
• ⚠ High-pressure mercury hazard — face shield and gloves mandatory.

Handling and Installation Requirements

• ⚠ HIGH-PRESSURE MERCURY — face shield and gloves mandatory. Extreme internal pressure. Face shield and heavy gloves required during all handling and installation. Lamp burst risk if dropped or mishandled.
• Mercury vapor hazard: If lamp breaks, evacuate, ventilate, and follow local mercury spill protocols.
• DC power supply required: Dedicated constant-current DC supply rated for 3500W at 55V, Type: DC.
• Burn position — Anode Up Burn Position: Incorrect orientation causes arc instability and shortens lamp life.
• Do not touch lamp envelope. Use clean gloves at all times.
• Allow 30-minute cool-down before handling.
• Mercury disposal: Contains mercury. Visit lamprecycle.org.
