Replacement Fluorescent Ring Tubes for Stereo Microscopes Overview These two fluorescent ring tubes are designed as direct replacement lighting sources for stereo microscopes that accept a 78mm inner diameter ring. Each tube is rated at 10W and provides consistent ringshaped illumination to reduce shadows and improve visibility when inspecting small objects. Key benefits Accurate, even illumination: Ring shape delivers uniform light around the objective, minimizing shadows and improving visibility of surface details. Simple replacement: Sold as a pair to restore balanced lighting and simplify installation when replacing old or failed tubes. Fits larger ring mounts: 78mm inner diameter design accommodates stereo microscope models that require a larger ring opening. Practical for precision work: The consistent fluorescent light supports closeup inspection and handling tasks by improving contrast and detail clarity. Specifications Quantity: 2 pieces Power: 10W per tube Type: Fluorescent ring lamp tube, ring lighting source, replacement tube Inner diameter: 78mm, suitable for stereo microscopes using larger ring lamps Compatibility and fit Intended for stereo microscopes that use fluorescent ring lighting with a 78mm inner diameter. Use these tubes as replacements for existing ring lamp housings that accept 78mm inner diameter tubes. Confirm your microscope lamp opening and socket style before ordering. Performance and use Provides steady, diffuse illumination ideal for observing surface features and performing fine tasks under a stereo microscope. Replacing both tubes at the same time helps maintain balanced color and brightness across the ring light. Typical applications Electronics inspection and soldering: Improve visibility when examining circuit boards, components, and solder joints. Jewelry and watch : Reveal fine details and surface finishes for precise adjustments and cleaning. Laboratory, education, and hobby work: Support specimen sorting, dissection prep in nonmedical settings, model building, and other closeup tasks that benefit from shadow lighting. Installation notes Sold as replacement tubes only. Ensure compatibility with your microscope lamp housing and socket connections. If you are replacing an existing pair, install both tubes to maintain even light output. What this product solves Restores or upgrades microscope ring illumination without replacing the entire lamp assembly. Eliminates uneven lighting and dark spots caused by worn or broken tubes, improving observation accuracy and reducing eye strain during detailed work.
