Stage and studio halogen lamp

The Ushio DWY/FAB JPD120V-650WS is a 650 watt halogen bulb built for professional stage and studio fixtures. It operates on 120 volt mains and uses an R7s recessed single contact base with a CC-8 filament. The lamp delivers 20000 lumens at a 3400K colour temperature for bright white output. It is sold new as a direct replacement for compatible double ended sockets.

Sustained output and rated life

The lamp is rated for 25 hours of life at full 650 watt power. Output and colour remain stable during that period because the halogen cycle maintains filament integrity. The short rated life reflects the high intensity design intended for production runs rather than continuous daily lighting. Fixtures must provide adequate ventilation to reach the specified lifetime.

Compatibility checks before ordering

Verify that your fixture accepts an 80mm long R7s double ended lamp and is rated for 650 watts at 120 volts. Confirm the socket matches the recessed single contact base type. Ensure the dimmer or ballast is compatible with halogen CC-8 filaments. This lamp is not suited for fixtures requiring longer life or lower wattage.

Questions about this item

How much heat does the 650 W halogen bulb generate during extended use?

The 650 W rating means most input power becomes heat; the 3400 K colour temperature and 20000 lumen output confirm high thermal load, so ensure the fixture and surrounding area can dissipate it safely.

What fixture base must I already have for this R7s double-ended lamp to work?

The lamp requires a recessed single-contact R7s socket that accepts an 80 mm long double-ended bulb; verify the fixture matches this base type and length before purchase.

Will the 25-hour rated life be shorter if I dim the 3400 K output with older dimmer modules?

The 25-hour life is rated at full 120 V operation; dimming can extend or reduce life depending on filament temperature stability, so consult the dimmer specifications for halogen compatibility.
