Sylvania 54089 HTI 250 W/32C

Osram 54089 HTI 250 W/32C — 250W HTI Reflector Metal Halide Short-Arc Lamp, 45V, 5600K, CRI 70, 32mm Focal Length

The Osram HTI 250 W/32C (product number 54089) is a 250W HTI metal halide short-arc discharge lamp built into a dichroic focusing reflector. It operates at a nominal 45V and 6A on AC, produces a 5600K daylight-balanced arc with a color rendering index of Ra 70, and carries a nominal lifetime of 250 hours. The integrated reflector has a 32mm focal length — the "32" in the product name — and the lamp ships with a connecting cable and plug contact. The reflector assembly measures 67.0mm in diameter and 73.0mm in length. This is a light guide and projection source rather than a general fixture lamp: the precision reflector alignment is designed to inject light efficiently into a light guide or optical system. Because of high luminance, UV radiation, and high internal operating pressure, this lamp may only be operated inside an enclosed lamp casing specifically constructed for the purpose, with appropriate UV filtering. Confirm the lamp base, focal length, and casing before ordering.

Packaging and Logistics

The folding carton is the smallest orderable unit. When ordering, quantities should be entered as single or multiple shipping units.

Product Overview

HTI lamps are metal halide short-arc discharge sources. The very small arc gap concentrates a large amount of light into a physically tiny emitter, which is what makes the source useful for optical systems that need to collect light from a near-point origin. This particular model integrates that arc tube into a dichroic focusing reflector with a 32mm focal length, aligned at the factory. The dichroic coating passes infrared through the back of the reflector rather than forward with the beam, which reduces the heat load delivered to whatever the light is being injected into.

The design intent is light injection rather than area illumination. Osram positions this lamp for highly efficient systems that feed light into a light guide, and the precision of the reflector alignment is the reason: a fiber bundle or liquid light guide has a small acceptance area and a limited acceptance angle, so coupling efficiency depends heavily on how accurately the source sits at the reflector focus. The lamp is specified to hold consistent lumen output across its life and offers higher luminous efficacy than conventional HID sources, which improves overall system efficiency.

Nominal lifetime is 250 hours. That is short by general lighting standards and normal for short-arc discharge sources of this class, where output stability and arc precision are the design priorities rather than service interval. Operating values are 250W at a nominal 45V and 6A on AC, and the lamp requires a power supply or ballast matched to those values. The lamp is supplied with a connecting cable and plug contact.

This lamp contains mercury and operates at high internal pressure. It must be run inside an enclosed lamp casing built for the purpose, with filtering that brings UV radiation down to an acceptable level. It is not suitable for open or general-purpose fixtures.

Compatible Applications

• Light guide systems — injecting light into fiber bundles or liquid light guides
• Medical endoscopy light sources
• Industrial borescopy and inspection light sources
• Light guide systems in the entertainment sector
• Concert lighting, club, and disco fixtures built around a light guide or projection optic
• Stage and theatre equipment using an enclosed short-arc source
• Studio, TV, and film equipment requiring a 5600K daylight-balanced discharge source
• Architectural and architainment installations using fiber optic light delivery
• Replacement lamp for equipment originally specified with HTI 250 W/32C

Before Ordering — Verify

• Confirm the equipment specifies the HTI 250 W/32C. HTI lamps of the same wattage exist in different reflector, focal length, and base configurations that are not interchangeable.
• Confirm the lamp base is FaXP2.5-2x65. This is a reflector lamp with an integrated base and connecting cable, not a bare double-ended or single-ended burner.
• Confirm the focal length required is 32.0 mm. The "32" in the product name refers to the reflector focal length, and a different focal length will not couple correctly into the same optical system.
• Confirm the reflector envelope fits: 67.0 mm diameter by 73.0 mm length.
• Confirm the power supply or ballast is matched to 250W at a nominal 45V and 6A AC.
• Confirm the fixture provides an enclosed lamp casing specifically constructed for short-arc discharge lamps, with UV filtering. This lamp must not be operated in an open or unfiltered fixture.
• Confirm the burning position permitted by the equipment. This lamp is rated p15/s15.
• Note the 250-hour nominal lifetime when planning spares and maintenance intervals.
• Note packaging: the smallest orderable unit is a single folding carton, and the shipping carton contains 2 pieces.
• Confirm mercury shipping and disposal requirements for the destination. This lamp contains mercury.

Safety and Handling Guidelines

• HTI lamps produce high luminance, emit UV radiation, and operate under high internal pressure. They may only be operated in enclosed lamp casings specially constructed for the purpose.
• Appropriate filters must be in place to reduce UV radiation to an acceptable level. Never operate this lamp without proper UV filtering.
• Never look directly at an operating arc. The luminance can cause eye injury.
• Disconnect power and allow the lamp to cool completely before handling or replacement. Short-arc lamps remain under high pressure while hot.
• Do not touch the quartz arc tube or reflector optical surfaces with bare hands. Skin oils cause localized heating and can lead to failure.
• Mercury is released if the lamp breaks. Special safety precautions must be taken. Consult the safety and handling leaflet supplied with the lamp or the equipment operating instructions.
• Follow the equipment manufacturer's instructions for lamp installation, alignment, and the permitted burning position.
• Do not exceed the rated nominal lifetime without evaluating the risk of end-of-life failure in a pressurized short-arc lamp.
• Dispose of the lamp in accordance with local regulations for mercury-containing lamps. See lamprecycle.org for recycling information.

Compliance

• Contains mercury. Subject to mercury lamp handling, shipping, and disposal requirements.
• WEEE marked — do not dispose of with general waste.
• REACh, Article 33 of EU Regulation (EC) 1907/2006: no declarable substances contained. No declaration in the SCIP database, and no candidate list substances.
• EEI energy label class B.
• METEL code OSRHTI25032C.
