OSRAM SFc10-4 69004 - Double-ended lampholder with key for HTI/SharXS lamps

The OSRAM SFc10-4 lampholder (ref. 69004) is a professional double-ended socket designed for HTI/SharXS metal discharge lamps and other SFc10-4 base lamps. It features a keylock system that ensures correct lamp positioning, mechanical stability, and a reliable electrical connection in entertainment and architectural lighting equipment. It is certified for up to 1500 W , 1000 V , and a 25 kV ignition pulse (suitable for hot restrike ), with a high-temperature T250 ceramic body. Its standard format offers a flat bottom support and a contact spacing of 115 mm (approximate total length 148.6 mm). Cables are not included, and it is ready for integration into moving heads and projectors from manufacturers such as Martin, Vari-Lite, and PR Lighting. Ideal as an original replacement or for preventative maintenance of equipment using SFc10-4 lamps.

Main features

• Base / type: SFc10-4 double-ended with key system (prefocus).
• Electrical compatibility: max. power 1500 W; max. voltage 1000 V; impulse voltage 25 kV (hot restart).
• Robust construction: high-temperature steatite/ceramic body (T250) and nickel contacts.
• Standard format: flat bottom support; lamp spacing 115 mm ; total length approx. 148.6 mm .
• No leads: Allows for wiring and terminals customized by the manufacturer or technical service.
• Quality and safety: UL recognized and CSA references, suitable for demanding show applications.
• Extended use: Widely used with OSRAM HTI/SharXS lamps and equivalent Philips MSR Gold lamps with SFc10-4 socket.

Product benefits

• Precise and repeatable assembly: the keyed prefocus prevents orientation errors and keeps the bow at the optimal point of the optical system.
• Maximum reliability under critical conditions: materials and design for high temperature (T250) and ignitions with peaks up to 25 kV.
• Fewer maintenance stops: quality nickel and ceramic contacts that reduce play, sparking and premature degradation.
• Field-proven compatibility: de facto standard in numerous professional moving heads and projectors.

Use cases

• Replacement for 400–1500 W moving heads with SFc10-4 lamps (e.g., Martin MAC 2000 series, Vari-Lite VL3000/VL3500, PR Lighting equipment).
• Metal discharge effect projectors and architectural luminaires that use HTI/SharXS or MSR Gold lamps with an SFc10-4 base.
• Preventive maintenance to restore contact and pre-focus when there are intermittent failures, blackening of contacts or mechanical play.

Frequently Asked Questions

• Is it compatible with “Baby SharXS”? No. Although some “Baby SharXS” models state an SFc10-4 base, their lamp length is shorter and they do not fit this lamp holder.
• Does it include cables or terminals? No. It is the "NO LEADS" version; it is wired according to the specifications of the luminaire manufacturer or the SAT (Technical Assistance Service).
• Does it support hot reignition? Yes, it is pulse rated up to 25 kV, suitable for ignition with high voltage igniters.
• What is the “keylock” or pre-focus? It is a notch/key on the SFc10-4 base that prevents the lamp from being mounted out of position and ensures optical repeatability.
• Do all SFc lamps use this socket? Only SFc10-4 with a pre-focus notch fit ; other bases like SFc15.5 do not have that notch and are not compatible.

Lamp compatibility (examples)

Among others, this lamp holder is used with multiple references of SFc10-4 base discharge lamps, such as:

• OSRAM HTI/SharXS: HTI 400/575/700/1200/1500 (versions D3/D4/D5/D7, 60/75), e.g. e.g. HTI 1200 W/D7/60 SharXS.
• Philips MSR Gold: 400W SA/2/DE, 700W SA/2/DE, 1200W SA/DE / SA/2/DE, 1510W SA/DE, among others.

Note: Always check the SFc10-4 notched base and the total lamp length as indicated by the luminaire manufacturer.
