Lamps, Holders & Accessories is a category within optoelectronics that covers light-emitting lamp components and the supporting hardware used to mount, secure, and interface them within electronic and electromechanical assemblies.

It typically includes:

• Lamps: light sources designed to provide visible or non-visible illumination or indication.
• Holders: mechanical and electrical interfaces that position the lamp and provide connection points.
• Accessories: complementary items that aid installation, retention, protection, or integration of lamp assemblies.

These products are generally selected to ensure reliable physical fit and consistent electrical interfacing between the lamp and the surrounding system.
