An S8 Incandescent bulb is a small, round incandescent bulb commonly used in applications requiring low to moderate lighting.

Key Characteristics:

• Shape and Size: The "S" stands for "Sign", and the "8" indicates the bulb's diameter, which is 8/8 inches or 1 inch (25.4 mm) in diameter.
• Applications: S8 bulbs are often used in marquee lights, automotive indicator lights, appliance lighting, and industrial equipment. They’re also used in some decorative light fixtures, like string lights or signage.
• Voltage and Base Options: Available in a range of voltages, like 6V, 12V, and 120V, and various base types, such as E17 (intermediate) and BA15S (bayonet).
• Light Output: As with other "S" bulbs, S8s provide a modest light output and usually emit a warm, steady glow, though LED versions can offer cooler color options and longer lifespans.

S8 incandescent light bulbs are chosen for their compact size and reliable performance in a variety of low-profile lighting fixtures.
