Osram 11619 BBA 118V Photo-Optic Lamp - 250W 120V Med

Osram 11619 BBA — 250W 120V Photoflood Lamp, Medium Base, A21, 8700 Lumens

The Osram 11619 BBA is a 250-watt, 120V photoflood lamp from OSRAM, designed for professional photographic, projection, microfilm, microscope, studio, medical, fiber-optic, and entertainment lighting equipment. With a medium screw base, A21 bulb shape, 8,700 initial lumens, and a rated average life of 4 hours, this lamp is built for short-duration, high-output applications where light output and color stability are prioritized over service life. Match the ordering abbreviation, wattage, voltage, base, and bulb shape to your existing lamp or equipment manual before ordering.

Technical Specifications

Product Overview

OSRAM photoflood and photo-optic halogen lamps are engineered for equipment where optical alignment, color stability, and precise lamp geometry matter more than long operating life. The 4-hour rated average life is standard and expected for this lamp class — photoflood lamps trade service life for very high lumen output and color temperature stability, since they're typically used for short, controlled sessions (photography, projection, optical instrumentation) rather than continuous operation.

These lamps are commonly specified for projectors, microfilm and microfiche readers, microscopes, studio and entertainment fixtures, medical illumination systems, and fiber-optic illuminators. Because optical equipment is often designed around the precise filament geometry and light center length of a specific lamp, exact replacement matching by ordering code is especially important in this category — substituting a similar-looking lamp can shift focus, beam position, or color output even if wattage and base match.

Compatible Applications

• Projectors and slide projection systems — High-output illumination for optical projection equipment.
• Microfilm and microfiche readers — Precise, stable illumination for document imaging systems.
• Microscopes and laboratory illuminators — Bright, color-stable light for optical and scientific instruments.
• Studio, theatre, TV, and video lighting equipment — High-output photoflood illumination for production lighting.
• Medical and dental illumination systems — Where specified by equipment manufacturer.
• Fiber-optic illuminators and optical equipment — Light source for fiber-optic and specialized optical systems.

Before Ordering — Verify

• Ordering Code: Match OSRAM 11619 / BBA 118V exactly to the existing lamp or equipment manual — optical equipment is sensitive to exact lamp geometry.
• Voltage: Confirm the equipment is rated for 120V operation.
• Wattage: Confirm the fixture or instrument is rated for 250W.
• Base: Confirm the socket accepts a Medium base lamp.
• Bulb Shape: Confirm A21 bulb shape and physical clearance within the equipment housing.
• Life vs. Output Tradeoff: Long-life photo lamp versions typically produce fewer lumens, while high-output versions like this one have a correspondingly shorter rated life — confirm this tradeoff suits your application before ordering.

Safety and Handling Guidelines

• Use Approved Fixtures Only: Install only in equipment specifically designed for this lamp type, wattage, voltage, and base.
• Do Not Touch the Quartz Envelope: Use clean gloves or a lint-free cloth. Skin oils cause hot spots that lead to premature lamp failure.
• Disconnect Power Before Replacement: Turn off and unplug equipment before installing or removing this lamp.
• Allow Cooling: Let the lamp and fixture cool completely before handling — this lamp class runs at high temperature even over short durations.
• Optical Alignment: Seat the lamp correctly and fully to maintain proper focus, beam position, and equipment performance.

Compliance

• Mercury-free tungsten halogen lamp — no mercury-related shipping restrictions apply.
• Verify RoHS compliance status with the OSRAM manufacturer specification sheet prior to use in regulated installations.
