Halogen Replacement Bulbs for Microscopes & Fiber Optic Illuminators

The specialty lamps that keep legacy inspection stations performing the way they were designed.

Halogen replacement bulbs remain a critical consumable for many microscope light boxes and fiber optic illuminators because they deliver broad-spectrum “white” light, stable intensity control, and strong color fidelity that technicians rely on for defect detection and surface inspection. Common microscope/illuminator halogen formats (often MR16 reflector lamps) include types such as EKE (21V 150W, GX5.3 bi-pin, ~200 hr life)—widely used in medical/scientific microscopes and fiber optic illumination systems.

Because many general-use halogen categories have been phased down over time, facilities increasingly treat these as specialty lamps and plan replacements proactively to avoid downtime or requalification of inspection stations. Browse below to find the correct halogen replacement bulb by matching the essentials—voltage, wattage, base type, reflector style, and lamp code (ANSI/part number)—so your microscope or fiber optic illuminator returns to its intended brightness and performance.
