Bi-pin light bulbs have long been used in a wide variety of concealed commercial and residential lighting applications because they're easy to install and deliver a high light output from a small body. Increase energy efficiency and reduce maintenance by replacing old or worn out incandescent bulbs with bi-pin LED bulbs from BulbAmerica. We carry a large selection of bi-pin bulbs to choose from, including LED G4, G8 and G9 bulbs. These types of lights can be used in landscape lighting, decorative lighting, pendant fixtures, down lights and much more. They can even be used in signage, display lighting and under-cabinet lighting because energy efficient G4 LED bulbs are designed to last for up to 50,000 hours.
