OSRAM HTI 152 W GY9.5 - Metal halide lamp (≈150 W, 90 V, 5000 K) for entertainment lighting
The OSRAM HTI 152 W (commonly marketed as “ HTI 150 W ”) is a short-arc metal halide lamp with a GY9.5 base, designed for professional entertainment lighting applications (stage, club, theater, TV, and architectural). It offers 5000 K daylight with a CRI ≥ 80 and a nominal luminous flux of 10,000 lm , maintaining stable output throughout its 2,000-hour lifespan . Its compact geometry ( LCL 30 mm , Ø 20 mm , length 48 mm ) and universal burn-in position facilitate integration into compact fixtures. It requires forced cooling and a compatible ballast/ignitor .
Main features
-
Power and supply: 152 W (nominal ≈150 W), 90 V , 1.7 A ; 4.5 kVp start-up (cold start) , AC current.
-
Light and color: 5000 K (daylight white), CRI ≥ 80 , 10,000 lm , ≈67 lm/W .
-
Short arc optics: 6.8 mm electrode gap for high luminance and sharp beams.
-
Compact format: LCL 30 mm , diameter 20 mm , length 48 mm ; weight approx. 9.5 g .
-
Operation: Burning position: any ; forced cooling (fan) ; nominal life 2,000 h .
-
Thermal resistance: XS type seal with up to 450 °C at the pinch point (according to HTI family).
-
Logistics: individual unit and shipping box of 12 units for replacements.
Product benefits
-
High visual impact due to its high luminance and highly concentrated beam.
-
Consistent color (5000 K) throughout its lifespan, ideal for mixing with LEDs and other sources.
-
Easy integration into multiple moving heads and compact projectors with GY9.5 base.
-
Optimized maintenance thanks to the 2,000 h nominal life and reduced size.
Use cases
-
Lighting for concerts and festivals : precise beams and defined gobos.
-
Club and disco : high brightness effects and vivid colors.
-
Stage and theatre : compact effects projectors, moving heads spot/beam.
-
Studio, TV and film : spot effects and daylight props.
-
Architecture and architainment : projection of beams and textures outdoors (appropriate lighting).
Frequently Asked Questions
-
Is it “HTI 150” or “HTI 152”? The official model is HTI 152 W (90 V); in the market it is often referred to as “ HTI 150 W ”. The sockets and dimensions are the same.
-
Can it be dimmed? Dimming HID lamps is generally not recommended; level control is achieved with the luminaire's shutters . Always follow the equipment manufacturer's instructions.
-
Does it need ventilation? Yes, forced cooling (fan) is required to ensure stability and a long service life.
-
UV protection and internal pressure? Use only in enclosed housings with UV filters and protective measures. Handle with appropriate PPE.
Installation and safety recommendations
- Check electrical compatibility of the projector: 90 V , ≈150–152 W , GY9.5 , ignitor 4.5 kVp .
- Install without touching the bulb; clean with a lint-free cloth if necessary.
- Ensure airflow and temperatures within limits (pinching up to 450 °C depending on family).
- Respect usage cycles and cooling times before restarting.
