Set the Mood With Northlight Bulbs for Outdoor String Lights

String lights are a versatile way to light up any indoor or outdoor space. They come in a wide variety of colors, shapes and sizes. At Lowe’s, we offer both incandescent and LED Northlight string replacement bulbs, as well as other Northlight string light replacement bulbs.


LED and incandescent Northlight bulbs both produce the same light output, but LEDs have lower wattage than incandescent Northlight bulbs. Edison Northlight bulb string lights, which create a retro effect, often use incandescent Northlight bulbs. Some Northlight string light packs feature a single color, while others come in a festive, multicolor mix. 


Bulbs for outdoor string lights come in many options, making them a great tool for lighting up your patio or deck in style.
