OSRAM HPL 750W/230V (Ref. 93729) – HPL 3200 K halogen lamp with G9.5 base (heat sink) for Source Four and theater cutouts

OSRAM HPL 750W/230V (Ref. 93729) – HPL 3200 K halogen lamp with G9.5 base (heat sink) for Source Four and theater cutouts

The OSRAM HPL 750W/230V (code 93729 ) is the reference halogen lamp for ETC Source Four-type trim lights and equivalent luminaires. Its ultra-compact filament (UCF) design maximizes optical performance, delivering 19,750 lm at 3,200 K with a CRI of 100 and a rated life of 300 hours . It features a G9.5 base with a heat sink to withstand high temperatures and maintain filament geometry, and is optimized for the TP22H lamp holder. Thanks to its 6-C8 filament and 7.5 × 11.5 mm illuminated field , it provides a sharp beam with excellent edge definition in trim optics.

Main features

• Studio performance : 19,750 lm , 3,200 K , CRI 100 ; camera-calibrated tungsten light.
• UCF Filament : Ultra Compact Filament design for greater punch and beam uniformity.
• Robust construction : G9.5 base with heatsink , reinforced pinning and foam packaging for secure assembly.
• Compact measurements : Ø 19.0 mm , length 104 mm , LCL 60.3 mm ; weight 60 g .
• Operation : 750 W , 230 V , adjustable , universal burn position (Any) .
• Optimal with TP22H lamp holder; designed for fixtures of the Source Four family.

Product benefits

• More usable light on the plane thanks to the UCF filament and 6-C8 geometry (cleaner beam and more defined cutouts).
• Constant color (3200 K) and impeccable color reproduction ( Ra 100 ).
• Mechanical and thermal stability : heat sink at the base and reinforced clamping for intensive cycles.
• Broad compatibility with Source Four ecosystem and equivalent PAR/PARNel and clipping.

Use cases

• Theatre and concert halls : cutouts, zoom cutout, Par/ParNel.
• Television and cinema : key/fill/backlight with 3200 K tungsten.
• Events and rental : stage lighting, gobos and precision cutouts.

Frequently Asked Questions

Does it fit ETC Source Four projectors? Yes. OSRAM HPL lamps are specifically designed for the Source Four ecosystem and compatible with the heat sink socket ( TP22H recommended), following HPL's license for these devices.

Is it dimmable? Yes. It supports dimming with resistive loads; when dimmed, the tone becomes warmer ( amber shift ).

What is its lifespan? 300 nominal hours under standard conditions.

Can it be used in any orientation? Yes, universal burning position (Any) .

Installation and safety

• Use in luminaires designed for stage halogens with adequate protection against fragments and UV.
• Do not touch the quartz with your fingers; assemble with gloves or a clean cloth to avoid shortening its lifespan.
• Check TP22H lamp holder or equivalent and space for heat dissipation.
