Compatibility & Fitment

These C9 bulbs fit E17 intermediate screw sockets used in C9 string lights. They are intended for indoor and outdoor Christmas lighting, exterior patio lines, decorative lighting, Christmas villages, chandeliers, nightlights, plug-in nightlights, salt lamps, salt baskets, and electric candles. The bulbs operate from a 120-volt AC power source.

Each bulb measures 1.25 inches in diameter by 2.75 inches high. The plastic construction provides a shatter-resistant alternative to glass incandescent bulbs.

When to Replace

Replace a bulb when it flickers, becomes noticeably dimmer, changes colour, fails to illuminate, or shows a cracked shell or burnt base. On a string light, replace individual bulbs when one section is dark or a socket no longer produces light.

Installation Tips

  • Turn off and unplug the string light or fixture before removing a bulb.
  • Allow a recently used bulb and socket to cool before handling.
  • Hand-tighten the E17 bulb into the socket; do not force or overtighten it.
  • Use only in sockets rated for the bulb's 120-volt AC supply.
  • For outdoor use, install in compatible outdoor sockets and protect connections from standing water and moisture.

FAQs

These are C9-shaped LED bulbs with an E17 intermediate base, measuring approximately 1.25 inches in diameter and 2.75 inches high. Check that your string-light socket is E17 before ordering; C9 refers to the bulb shape, not the socket size.
Yes. They are designed for indoor and outdoor Christmas string-light applications. For outdoor use, install them only in string lights and sockets rated for outdoor service, and keep electrical connections protected from standing water.
The bulbs use a shatter-resistant plastic shell rather than glass, making them more suitable for areas around children, pets, and outdoor decorations where accidental impacts may occur. They can resist breakage better than glass bulbs but should still be handled and installed carefully.
Each bulb consumes just 0.6 watts, so it produces substantially less heat than a comparable incandescent bulb. This makes them a practical choice for extended use on Christmas light strings and decorations, while the string and sockets should still be used within their rated limits.
These bulbs operate on standard 120-volt AC power used in North America. Use them with compatible 120V AC string-light sockets rather than low-voltage systems.
Each 0.6-watt LED bulb provides a 5-watt incandescent-equivalent light output, helping reduce energy use on a 25-bulb string. The rated operating life is up to 15,000 hours, with warm white 2200K light and approximately 350 lumens of listed brightness.
