Festoon Bulbs: Choosing the Right Bulb for Your Outdoor String Lights

Which festoon bulb shape creates the best look?

Round (G45 or G95) festoon bulbs produce the most even, classic festoon appearance. Vintage Edison (ST64) adds a filament character suited to rustic or industrial outdoor settings.

Do I need shatterproof festoon bulbs?

Shatterproof bulbs use a polycarbonate envelope instead of glass, making them impact-resistant and safer in high-traffic areas and commercial venues.
