Compatibility & Replacement

Fixture type: This double-ended mercury short arc lamp is designed for professional UV curing systems, microscopes, and analytical instruments that accept a 100W/20.5V mercury arc lamp with double-ended contacts. Common in OEM equipment from manufacturers such as Zeiss, Leica, Nikon, and UV curing system integrators.

Base: Double-ended – specific connector type not specified. Verify physical fit and electrical contact configuration with your existing lamp or equipment manual.

Ballast: Requires a dedicated ballast/power supply designed for 100W mercury short arc lamps (20.5V operating voltage). Do not operate directly on AC mains.

Before ordering, confirm:

• Equipment compatibility: Verify your instrument or curing system specifies Osram Sylvania #69217 or equivalent.
• Voltage – 20.5V: Confirm ballast output matches lamp voltage rating.
• Base type: Physically verify the double-ended connector type (e.g., R7s, other) with your existing lamp.
• Physical dimensions: Confirm your fixture accepts an 82 mm overall length lamp.
• Burn position – horizontal ±90°: Ensure your equipment operates the lamp in the horizontal plane (within 90° of level).
• Ballast compatibility: Use only with a ballast/power supply rated for 100W mercury short arc lamps. Incorrect ballast will damage the lamp and may cause rupture.

ADL Supply recommends confirming all applicable compliance data with the Osram Sylvania official product data sheet (SKU 69217) prior to specification or installation.

Safety & Handling Notes

• High pressure warning – face shield required: Mercury short arc lamps operate under very high internal pressure. Always wear a face shield and protective gloves during handling and installation. Lamp rupture can cause serious injury.
• No bare hands: Never touch the quartz envelope with bare skin. Oils cause hot spots leading to premature failure or lamp burst. Use clean gloves or a lint-free cloth.
• UV radiation hazard: Mercury short arc lamps produce intense UV radiation. Use only in approved enclosed fixtures with proper UV shielding. Never operate without protective housing.
• Mercury content: This lamp contains mercury. Dispose in accordance with local, state, and federal regulations. Do not break or crush.
• Do not exceed rated voltage: Operating above 20.5V dramatically shortens lamp life and may cause rupture. Verify ballast output before installing.
• Burn position – horizontal ±90° only: This lamp is rated for horizontal operation within 90° of level. Incorrect orientation can cause premature failure or lamp burst.
• Hot restart: Allow lamp to cool completely before restarting (minimum 10-15 minutes). Hot striking may fail or damage the lamp.
• Warm-up time: Mercury short arc lamps require a brief warm-up period to reach full output. Do not cycle power rapidly.
• Extreme heat: Use only in approved luminaires designed for high-temperature short arc lamps. Ensure adequate ventilation.
• Allow complete cool-down before handling: Allow lamp to cool completely before relamping. Do not touch immediately after switching off.
• Follow your equipment manufacturer's service documentation for lamp replacement procedures.
