An R14 incandescent bulb is a small reflector bulb with a diameter of 14 eighths of an inch, or 1.75 inches. The "R" stands for "reflector," meaning the bulb has a built-in reflective coating to direct light in a specific direction, creating a focused or spot-like beam.

Common uses for R14 bulbs include:

  1. Accent Lighting: Similar to R12 bulbs, R14 bulbs are used to highlight certain areas or objects, such as artwork or decorative pieces.

  2. Display and Cabinet Lighting: Their small size makes them suitable for display cases or under-cabinet lighting in kitchens or closets, providing bright, focused light in compact spaces.

  3. Track Lighting: R14 bulbs are often used in small track lights for adjustable, focused lighting, especially in residential or small retail spaces.

  4. Appliance Lighting: They are sometimes used in appliances, including refrigerators, where compact, directional lighting is needed.

  5. Recessed Lighting: R14 bulbs work well in small recessed fixtures where focused light is needed without taking up too much space.

These R14 incandescent light bulbs are available in various wattages and light outputs, including LED options, which are more energy-efficient. Their small size and ability to produce a directional light make them useful in settings where precision lighting is important.
