Osram 54534 FDN 500W 120V R7s Quartz Halogen Lamp, 3200K, CRI 100, 400 Hours

Osram 54534 FDN 500W 120V – 500W Quartz Halogen Lamp, R7s Base, 3200K

The Osram 54534 (FDN 500W 120V 12/CS 1/SKU) is a 500-watt double-ended tungsten halogen lamp from OSRAM, with an R7s base, rated at 3200K color temperature and a CRI of 100. It carries a 400-hour rated average life and delivers 12,800 initial lumens. This lamp is also cross-referenced under GE order code 23734 (GE description FDN-Q500T3/4) for the identical physical lamp. This lamp is stocked by ADL Supply for stage, studio, and entertainment lighting replacement programs.

Technical Specifications

Note: This is an Osram-branded product (manufacturer datasheet ZMP_4059425_54534.pdf, © OSRAM GmbH). The GE order code 23734 is included only as a cross-reference for the identical physical lamp, since it appears in GE's own Stage & Studio catalog under that number — it is not this product's brand. One data conflict between the two sources is flagged, not silently resolved: GE's catalog lists LIF code P2/31 for order code 23734, while Osram's own datasheet for product 54534 lists the LIF code as not assigned ("–"). The two sources also give a slightly different length (Osram: 117.5 mm / 4.63"; GE catalog MOL: 4.69") — most likely a measurement-convention difference rather than a different lamp, but not independently confirmed.

Product Overview

The Osram 54534 is a double-ended tungsten halogen lamp built for 3200K color-consistent output with a CRI of 100, over a 400-hour rated life. It uses a T-3 quartz envelope with an R7s base rated for 120V AC operation. Per Osram, it offers instant-on operation, nearly constant luminous flux across its life, and is dimmable with the traditional incandescent amber shift.

Quartz halogen lamps are designed to be operated within close voltage tolerances; excessive voltage can drastically shorten life even as it raises light output. Halogen lamps of this type must only be operated in luminaires with suitable protective shields or grids so that no parts/shards can escape if the lamp bursts, and so that no ultraviolet radiation escapes during operation; the fixture should carry a warning label noting the high heat given off by the lamp.

Compatible Applications

• Stage and theatrical lighting instruments
• Studio, TV, and film production lighting
• Professional photography
• Club and disco lighting
• Retrofit replacement in fixtures originally specified for Osram 54534 or the cross-referenced GE order code 23734

Before Ordering – Verify

• Confirm the base type (R7s) and voltage (120V) match your fixture before ordering.
• Do not exceed 110% of rated voltage; overvoltaging shortens life and raises seal temperature.
• Confirm your fixture's rated burning position against H4 (horizontal, ±4°) per the GE cross-reference catalog listing.
• Confirm the 117.5 mm (4.63") lamp length clears your fixture's socket spacing.
• This lamp must be installed only in an enclosed luminaire with a protective shield or grid — do not use in an open, unshielded fixture.

Safety and Handling Guidelines

• Turn power off before inspection, installation, or removal — risk of electrical shock.
• Keep combustible materials away from the lamp and use only in an enclosed, shielded fixture rated for this product — risk of fire and UV exposure.
• Pressurized lamp: unexpected rupture may cause injury, fire, or property damage. Use eye protection and do not touch the glass with bare hands.
• Do not use the lamp if the outer glass is scratched or broken; operate only in the specified position; do not exceed 110% of rated voltage.
• Allow the lamp/fixture to cool before handling; turn power off before installing the lamp; dispose of a broken lamp in a closed container.
• The fixture must display a warning label indicating the lamp gives off high levels of heat.

Compliance

• REACh: SCIP database declaration is listed by the manufacturer as "in work" as of the datasheet date; confirm current status with Osram before regulated-market resale if required.
• Dispose of/recycle per federal, state, and local regulations for lamp components.
• ANSI code FDN — confirm ballast/transformer compatibility before installation.
