Sylvania 69182 - HBO - 103 W-2

The Sylvania HBO 103W/2 (103W 22.5V) is a precision high-pressure mercury short-arc lamp engineered for demanding scientific and industrial optical applications requiring intense UV and visible light output from a near-perfect point source. Delivering 2,550 lumens at 30 LPW with 270 candle power through a double-ended T10 envelope with integral reflector, this DC-powered HBO lamp provides a 300-hour rated service life and is the standard replacement source for UV light curing systems, photo-polymerization equipment, and fluorescence microscopy illuminators.

ADL Supply Expert Application & Replacement Guide

The Sylvania HBO 103W/2 is primarily used by laboratory technicians, biomedical equipment service personnel, and industrial process engineers as the standard replacement arc source in fluorescence microscopy illuminators, UV light curing stations, photo-polymerization systems, and precision UV photoscientific instruments where the HBO mercury arc platform's near-perfect point source geometry and intense UV output in the 450–500nm wavelength range are required by the optical system design. This lamp requires a dedicated DC electronic power supply specifically designed for HBO mercury short-arc lamp operation — standard AC ballasts of any type (magnetic or electronic, metal halide, fluorescent, or HID) are not compatible. The equipment's internal regulated DC power supply must output exactly 22.5V at the rated current under operating load. The burn position is restricted to horizontal ±90° — vertical base-up or base-down mounting is not permitted and will cause arc instability and premature lamp failure. The 300-hour rated service life is a calibrated parameter; biomedical facilities should track runtime hours per lamp and replace on a scheduled interval before the rated life threshold rather than waiting for lamp failure during critical instrumentation sessions.

Operation, Safety & Mounting Compliance

DC Power Supply Requirement, Burn Position & Restrike

HBO (High-pressure mercury arc) lamps are powered exclusively by regulated DC current from a dedicated electronic power supply designed specifically for mercury short-arc lamp operation. The DC supply regulates the precise ignition voltage, run-up current ramp, and steady-state operating current required for stable mercury arc performance — standard AC ballasts of any type lack these control characteristics and must not be substituted. The horizontal ±90° burn position restriction is a physical requirement of the mercury arc geometry — the mercury pool within the arc tube must maintain a specific orientation relative to gravity for arc stability. Following any power interruption, allow the lamp to cool completely before attempting re-ignition — mercury short-arc lamps cannot be hot-restarted and require full cool-down before the next ignition sequence.

Extreme UV Hazard, High-Pressure Safety & Mercury Disposal

This lamp emits extreme levels of ultraviolet radiation across UV and visible spectral ranges and operates at very high internal pressure — it must be installed exclusively in an approved enclosed optical instrument housing. Never operate this lamp outside its designed optical housing, and never look directly at the arc source even with UV-filtering eyewear during operation. Always use the manufacturer's supplied safety handling box when installing or removing the lamp — the high internal pressure creates a severe explosion and fragment hazard during handling of warm lamps. This lamp contains mercury and must be disposed of in accordance with applicable federal, state, local, and provincial hazardous waste disposal regulations — standard electronic waste disposal is not sufficient for mercury-containing high-pressure arc lamps.
