c9 red led lights

C9 red LED bulbs use the C9 bulb shape and typically have an intermediate E17 (Edison) screw base. Replacement C9 bulbs and retrofit C9 lamps use this E17 base.

Red C9 LED strings commonly come on green or white wire. Many sets include built-in clips at each bulb base to simplify attachment to trees, rooflines, garlands, and other surfaces.

Manufacturer-listed specs for C9 red LEDs typically show per-bulb energy use around 0.8–1 watt. Example lumen values that appear in product specs include about 105–120 lumens, and some listings give an incandescent-equivalent wattage of roughly 7–8 watts.

Many C9 red LED sets are UL-listed or carry similar indoor/outdoor safety certifications, but certification can vary by model—check the product label. Bulbs are generally made from non-glass, shatter-resistant materials and run cool to the touch.

Many C9 LED string sets use “stay-lit” circuitry so that if a single bulb fails or is removed, the remaining bulbs continue to operate. Behavior can vary by manufacturer, so check the product description for stay-lit or fail-safe claims.

Many C9 string sets include spare replacement bulbs and extra fuses, and often offer end-to-end connectors so multiple sets can be linked. Check the package contents for exact extras before purchasing.
