Ushio 1000217 DRB/DRC 120V 1000W

The Ushio Professional 1000217 DRB/DRC Lamp is an elite, high-output 1000W tungsten-halogen photo-optic bulb engineered for demanding television broadcast studios, theatrical stage events, and specialized optical projection systems. Delivering 26,000 initial lumens of clear, calibrated 3200K warm white performance, this heavy-duty T4 tubular single-ended capsule maintains a flawless 100 CRI color profile for absolute visual fidelity under active lens systems. Outfitted with a precision-machined P28s medium prefocus flanged base and a heavy-duty continuous filament core, it ensures repeatable positional alignment across theatrical fresnels, follow-spots, and ellipsoidal profile spotlights.

ADL Supply Expert Application & Replacement Guide

The Ushio 1000217 DRB/DRC is an entertainment industry benchmark utilized extensively by television studio master electricians, theater stage crews, and technical facility operators. This heavy-duty module is specified across professional studio fresnels, ellipsoidal reflector follow-spots, overhead stage borders, large-format slide projectors, and specialized optical instruments requiring absolute focus stability.

Critical Positional Mounting and Burning Angle Constraints: This 1000W incandescent source relies on a highly specialized **P28s medium prefocus base system**. The integrated locking flange ring registers the internal coil filament at a mathematically exact focal location relative to the fixture's primary lens alignment axis, ensuring crisp beam patterns across maintenance shifts. Master electricians must respect the **s90 operational boundary parameter: this capsule must be burned strictly Base Down to Horizontal**. Attempting to mount or burn this item in a completely upside-down (base-up) position traps massive convective thermal energy within the prefocus socket block, which triggers instantaneous electrical short-circuits and structural filament warping.

Operation, Safety & Mounting Compliance

Thermal Management and Handling Rules

Because 1000W studio lamps generate intense localized thermal envelopes and high internal structural pressures within seconds of ignition, always isolate incoming line feeds and allow a full 20-minute resting intermission for components to cool before performing re-lamping sweeps. Ensure fixture casing vents and tracking grids are clear of dust to assist integrated heat dissipation pathways.

Quartz Glass Preservation and Contamination Prevention

Never handle the clear T4 glass body wrapper with bare skin during installation sweeps. Human fingers deposit microscopic alkaline body oils that combine chemically with the quartz envelope during extreme thermal shifts. This contamination blocks essential heat moving paths, causing intense localized hot spots that trigger accelerated envelope devitrification, early structural clouding, and premature rupture under operating pressure. Installers must execute re-lamping sweeps using clean cotton tech gloves, a lint-free microfiber cloth, or its original cardboard sleeve wrapper. Clean meticulously with isopropyl alcohol if accidental baseline skin tracking takes place.
