High-intensity discharge lamp for professional

The OSRAM SYLVANIA HTI 400W D3 75 SHARXS SFc10-4 is a compact double-ended metal halide lamp built for professional effect lighting. It delivers 26000 lumens at a 7500K colour temperature with a colour rendering index of 80. The rated life is 1000 hours.

Short arc and eXtreme Seal technology for thermal

A 3 mm arc produces an average luminance of 55 000 cd/cm², enabling high system luminous efficacy in compatible fixtures. The eXtreme Seal construction allows the lamp to withstand significant thermal stress during operation. The SFc10-4 base requires a matching double-ended socket.

Modular SharXS family compatibility simplifies

Membership in the modular SharXS product family means this lamp fits existing SharXS optical systems without redesign. The optimised filling and improved bulb shape contribute directly to the 1000-hour lifespan. No separate ballast or ignitor is included in the package.
