Yescom USA, Inc. 11SSL022-BULB-07X4 Standard Bulb 100Pack C9 LED Cool White E17 UL

Cool White C9 LED Bulbs

These 100-pack cool white C9 LED bulbs fit standard E17 sockets and carry UL certification for safe indoor and outdoor use. The shatterproof, waterproof PC shell protects each bulb from weather exposure throughout the holiday season. Dimmable operation lets you adjust brightness when paired with a compatible dimmer switch. They are designed for effortless screw-in installation on existing string light sets.

Fits E17 String Light Sets

Each bulb screws directly into an E17 base, so no rewiring or special tools are required for replacement or new installations. The 100-count pack frees you from buying multiple smaller boxes when outfitting long runs or multiple trees. Shatterproof construction removes the worry of broken glass during handling or windy conditions. Weatherproof sealing keeps moisture out of the socket connection.

100-Pack Coverage and Limits

One hundred bulbs provide enough replacements or new points for large rooflines, wrap-around porches or several medium trees in a single colour scheme. Cool white output stays consistent across the set without the colour drift seen in mixed batches. The pack contains only cool white bulbs; red, green, blue, yellow or orange C9 bulbs are sold separately if you want a multicolour display. A dimmer switch is not included, so on/off control is the default unless you add one.
