500W R7s Halogen Replacement Lamp

This 500 watt halogen bulb operates at 120 volts and uses an R7s recessed single-contact base. It produces 12800 lumens at a 3200K colour temperature with a colour rendering index of 100. The double-ended design serves as a direct replacement for FDN-coded fixtures. Rated life is 400 hours.

Fixture Voltage and Base Compatibility

Confirm the supply voltage is 120 volts before installation to avoid premature failure. Verify the socket accepts an R7s recessed single-contact base and that the fixture is rated for 500 watts. Ensure the double-ended physical dimensions match the lamp holder spacing in your equipment.

Stage and Studio Lighting Applications

Suits users needing high-output 3200K halogen light for theatre, film or photographic fixtures that specify an FDN 500 watt lamp. Not suitable for buyers who want longer service intervals or lower heat output than the 400-hour rating provides. Not for fixtures requiring a different base type, voltage or wattage.

Questions about this item

Does the package include any fixtures or just the 54534 halogen bulb itself?

Only the FDN 500W 120V R7s double-ended halogen bulb is supplied; any R7s-compatible fixture must be purchased separately.

Should I pick a different wattage or colour temperature for general home lighting?

This model is fixed at 500 watts and 3200 K warm white; choose it when your fixture requires exactly that output and colour.

What does the 12800 lumen rating mean for brightness in a typical room?

At 12800 lumens and 3200 K with a CRI of 100, the lamp delivers very bright, accurate warm light suited to large spaces or task lighting.
