OSRAM 93520 FHS - MR13 300W 82V Halogen Lamp with Dichroic Reflector (GX5.3 Base)

OSRAM 93520 FHS - MR13 300W 82V Halogen Lamp with Dichroic Reflector (GX5.3 Base)

The OSRAM 93520 FHS is a halogen lamp with an MR13 reflector designed for technical and professional applications requiring a stable beam and accurate color rendering. Its 300W power and 82V voltage provide a nominal luminous flux of 650 lm with a CRI of 100 , ideal for visual inspection, microscopy, fiber optic illumination, and medical/dental equipment. The dichroic reflector directs visible light while dissipating some of the heat to the rear, protecting optics and sensitive samples. It features a GX5.3 socket , a focal length of 152.5 mm , a diameter of 42 mm , and a length of 45 mm , with an S90 firing position for safe and compliant installation.

Manufactured with precise filament and reflector alignment, this lamp offers instant start , near-constant lumen maintenance , and is dimmable with the characteristic halogen amber shift. Its average lifespan is 70 hours , making it suitable for environments where light quality and beam consistency are paramount. Available in individual boxes and 24-unit packs, it is a reliable solution for laboratories, industrial applications, and technical entertainment requiring ANSI FHS standards.

Frequently Asked Questions

• What does FHS mean? It is the ANSI code that identifies 300W/82V MR13 halogen lamps with a GX5.3 base and specific geometry.
• Is it dimmable? Yes, the lamp is dimmable and maintains a stable behavior with the typical shift to warm tones when dimmed.
• What does the s90 burning position mean? It indicates a controlled (vertical) operating position defined by the manufacturer; install the lamp according to the equipment instructions.
• Can the bulb be touched? Avoid direct contact with your fingers. Grease can reduce its lifespan; use gloves or a clean cloth.
• Do you need an enclosed light fixture? Use equipment with adequate protection that contains fragments in case of breakage and controls UV radiation, according to the manufacturer's instructions.

Compatibility and installation

• Confirm that your equipment indicates ANSI FHS / 300W / 82V / GX5.3 .
• Check depth and focal length of 152.5 mm for correct focusing of the optical system.
• Respect the s90 position and the thermal environment specified by the equipment manufacturer.

Safety and recommendations

• Operate only in suitable luminaires with UV protections, grilles or filters according to regulations.
• The lamp reaches high temperatures; allow it to cool before handling.
• Do not exceed the nominal voltage of 82V AC and use compatible power supplies.
