ADL Supply Expert Application & Replacement Guide
The Sylvania HTI 300W/75V is primarily used by entertainment lighting technicians, theatrical gaffers, and architectural effect lighting system engineers as a replacement lamp in professional moving head fixtures, scanner units, follow spots, gobo projectors, and specialty architectural effect luminaires designed for HTI 300W SFc10-4 lamp sources. HTI (Halogen Tungsten Iodide) short-arc metal halide lamps operate on electronic control gear (ECG) — dedicated electronic ballasts specifically designed for HTI discharge lamps. Standard AC magnetic metal halide ballasts are not compatible. The SFc10-4 base is a specialized 4-contact single-ended lamp cap used exclusively on HTI and similar short-arc entertainment discharge lamps — it is not interchangeable with G22 prefocus, GX9.5, or other entertainment lamp base formats, and the fixture's lamp socket must be specifically SFc10-4 before ordering. This lamp emits high levels of UV radiation and operates at high internal arc pressure — it must be operated exclusively in approved enclosed luminaire housings, and the manufacturer's supplied safety handling box must be used during installation and removal.

Verify Before Ordering
ECG Electronic Ballast Required — SFc10-4 Socket Only | High UV — Enclosed Fixture Mandatory
This lamp requires a dedicated electronic control gear (ECG) ballast specifically designed for HTI 300W discharge operation — standard magnetic metal halide ballasts are not compatible. Confirm your fixture uses an SFc10-4 4-contact lamp socket — this base is not interchangeable with other entertainment lamp cap formats. This lamp must be installed in an approved enclosed luminaire. Use the manufacturer's safety handling box during installation. High UV emission — enclosed fixture with UV shielding is mandatory.

Operation, Safety & Mounting Compliance
ECG Power Requirement, SFc10-4 Socket & Hot Restrike
HTI short-arc metal halide lamps operate on electronic control gear (ECG) — dedicated electronic ballasts that manage the specific ignition, run-up, and steady-state current parameters for short-arc discharge lamps. Standard AC magnetic metal halide ballasts lack the electrical characteristics required by HTI arc tubes and must not be substituted. The SFc10-4 4-contact lamp cap must be fully and correctly seated in the fixture's SFc10-4 socket — confirm the mechanical lock engages before powering the fixture. Following any power interruption, allow adequate hot restrike cool-down time per the fixture manufacturer's specification before attempting re-ignition.
UV Radiation, High Pressure Safety & Disposal
This lamp emits a high level of ultraviolet radiation and operates at high internal arc pressure — it must be installed exclusively in approved enclosed luminaire housings. Always use the manufacturer's supplied safety handling box when installing or removing this lamp — do not handle the lamp directly with bare hands or without the protective box. Do not operate with a cracked or damaged outer jacket. This lamp contains mercury and must be recycled through a certified lamp recycling program in compliance with applicable federal, state, local, and provincial hazardous waste disposal regulations — do not discard in standard municipal solid waste.
