OSRAM PAR64 64738/4 CP61 (EXD) - PAR 64 1000 W NSP GX16d Halogen Lamp (240 V, 3200 K) for Theater, Events and TV

The OSRAM PAR64 64738/4 CP61 (ANSI EXD) is a classic 1000W narrow-spot (NSP) halogen PAR 64 lamp with a GX16d base, designed for professional stage, touring, TV studio, and rental lighting applications . Its sealed construction with a fused parabolic reflector and glass lens ensures a uniform beam and very high peak intensity , ideal for defined, focused overhead beams and precise cuts. It delivers a color temperature of 3200K (typical CCT 3090K, CRI Ra 100) and is dimmable using standard dimmer packs, maintaining natural color rendering for both on-camera and live applications.

With a typical beam angle of 12°/10° (H/V) in the CP61 version , a peak intensity of 255,400 cd , and a useful luminous flux (Φ _use ) of 15,800 lm , the 64738/4 delivers the punch lighting designers seek for powerful accents and effects over smoke or fog. Its overall length of 152.4 mm , diameter of 204 mm , and LCL of 102 mm facilitate direct replacement in standard PAR64 fixtures. The rated average lifespan is 300 hours , and the recommended operating position is hs30 (do not tilt perpendicular to the filament).

Product benefits

• Narrow and sharp beam for crisp cutouts, aerial effects, and long-distance accents.
• Stable tungsten color (3200 K) with CRI 100 , perfect for camera and mixing with other warm sources.
• Easy replacement on any PAR64 GX16d can thanks to its standard format and 102 mm LCL.
• Sealed design with fused glass lens and reflector that improves robustness and beam consistency.
• Wide compatibility with phase-cut dimmer packs used in touring and fixed installation.

Use cases

• Concerts and festivals : powerful frontal beams or backlights that pierce the environment.
• Theatre and musicals : precise accents from bars and towers, defined backlighting.
• Television/studio : occasional reinforcements and effects with natural color reproduction.
• Clubs and corporate events : dramatic looks and textures combined with smoke/fog.

Frequently Asked Questions

• What is the difference between CP60, CP61 and CP62? CP60 = Very Narrow Spot (VNSP), CP61 = Narrow Spot (NSP, 12°/10° approx.), CP62 = Medium Flood (MF). 64738/4 corresponds to CP61 .
• Can it be dimmed? Yes, it is dimmable with conventional dimmers suitable for 1000 W/240 V.
• Does it need a ballast? No, it's a mains halogen lamp (240V). It only requires a compatible GX16d lamp holder and, if desired, a dimmer.
• What is the lifespan? 300 nominal hours under correct usage conditions.

Installation and safety

• Use only in suitable (covered) light fixtures that contain possible fragments in case of breakage.
• Due to the heat generated, use high-temperature resistant lamp holders and do not operate near people or heat-sensitive or flammable materials.
• Respect the hs30 working position (do not tilt perpendicular to the filament) to ensure performance and lifespan.
