Technical Specifications

Product Overview

The Osram 11522 ECA is a professional tungsten incandescent super photoflood lamp engineered for studio, TV, film, stage, theatre, and professional photography applications. At 3200K with CRI 100 and nearly constant luminous flux over lamp life, it delivers stable, tungsten-balanced color output suited for film and television production, photographic lighting, and theatrical applications where accurate, consistent color temperature is critical.

The 20-hour rated life is standard for a high-output 250W super photoflood operating at full rated voltage — maximize lamp life by ensuring supply voltage does not exceed 120V. The lamp dims with traditional amber shift, which is expected and characteristic of tungsten incandescent sources. Instant-on operation with no warm-up delay.

Compatible Applications

• Studio, TV, and film lighting — 3200K tungsten-balanced output for camera-accurate production lighting.
• Stage and theatre lighting — Super photoflood for theatrical fixtures requiring ECA-designated lamps.
• Professional photography — Consistent color and instant-on performance for photographic studio equipment.
• Projectors, microfilm readers, and laboratory illuminators — Where ECA-designated lamps are specified by equipment manufacturer.

Before Ordering — Verify

• ANSI Code / Ordering Abbreviation: Confirm the existing lamp or equipment manual specifies ECA or ECA 250W 120V.
• Voltage: Confirm equipment is rated for 120V. Operating above rated voltage shortens lamp life.
• Wattage: Confirm the fixture or instrument is rated for 250W.
• Base Type: Confirm the socket accepts an E26 Medium Brass base.
• Bulb Shape: Confirm the A23 shape and 149.2mm length fit within the equipment's lamp housing with adequate clearance.

Safety and Installation Guidelines

• Approved Fixtures Only: Install only in equipment designed for this lamp type, wattage, voltage, and base.
• Disconnect Power: Turn off and unplug equipment before replacing the lamp.
• Allow Cooling: Let the lamp and fixture cool completely before handling — this lamp operates at high surface temperatures.
• Optical Alignment: Seat the lamp correctly to maintain proper focus, beam position, and equipment performance.
• Handle with Care: Inspect the bulb for cracks or damage before installation. Do not use a damaged lamp.
