An S14 incandescent bulb is a medium-sized, rounded bulb often used in decorative, outdoor, and signage lighting where moderate brightness and durability are needed.

Key Characteristics:

• Shape and Size: The "S" stands for "Sign", and "14" indicates a diameter of 14/8 inches, or 1.75 inches (44.5 mm).
• Applications: S14 bulbs are commonly used in string lights for patios and gardens, signage lighting, marquee lights, restaurants, and event lighting. They’re ideal for creating ambient or decorative lighting in outdoor and commercial settings.
• Voltage and Base Options: These bulbs come in various voltages (typically 120V for string lights) and are often paired with an E26 (medium) base for easy installation.
• Light Output: S14 bulbs are available in incandescent, LED, and even color-changing options. Incandescents provide a warm, soft light, while LEDs offer energy efficiency, various color temperatures, and improved durability, especially for outdoor use.

With their classic look and size, S14 incandescent light bulbs are popular for creating inviting, stylish lighting in both indoor and outdoor spaces.
