Ushio 1000293 EHR JPD 120V 400W Halogen Standard Bulb

Ushio 1000293 EHR JPD Halogen Projector Bulb

The Ushio 1000293 EHR JPD is a 400W halogen projector bulb operating at 120V with an R7s base. It delivers 7750 lumens at a 2900K color temperature for photography, stage and studio lighting. The double-ended quartz design provides bright, white light with high color stability. Rated life is 2000 hours.

Sustained Output Stability for Studio Sessions

Under continuous operation the bulb maintains consistent 2900K color temperature and 7750 lumen output throughout its 2000-hour rated life. Halogen quartz construction resists output drift during long photography or stage sessions. The R7s base ensures secure electrical contact without flicker. Performance remains steady rather than fading after initial warm-up.

Thermal Management and Power Draw

The 400W halogen filament generates significant heat during normal use at 120V, requiring fixture ventilation. Quartz envelope handles high operating temperatures without deformation. Power draw remains constant at rated wattage throughout the 2000-hour lifespan. No active cooling components are present in the bulb itself.
