Types of Bulb Holders
Edison Screw (E)
The Edison screw is the most common type of bulb holder. It features a threaded base that screws into the socket. This type is ubiquitous in residential lighting, from table lamps to ceiling fixtures. The ease of installation and wide availability of compatible bulbs make it a popular choice for many homeowners.
Bayonet (B)
Bayonet bulb holders utilize a two-pin fitting that pushes into the socket and twists to lock. This system offers a secure connection, which is particularly useful in decorative lamps and some ceiling fixtures. While they are less common than Edison screws, they are appreciated for their reliability and straightforward bulb replacement process.
GU10
GU10 holders are designed for spotlights and feature a two-pin fitting that twists into place. Their compact size makes them ideal for recessed and track lighting applications. The twist-lock mechanism reduces the chances of the bulb being inadvertently removed, providing a secure fit.
G4
G4 holders have a bi-pin base used primarily for low-voltage applications. They are commonly found in under-cabinet lighting and decorative fixtures. While these holders are compact and versatile, they require a transformer, which adds to the complexity of installation.
R7s
The R7s lamp holder is a linear bulb holder typically used for halogen bulbs in floodlights and work lamps. This type provides a high light output, making it suitable for applications where brightness is crucial. However, the bulbs can be fragile, and their use is generally limited to specific settings.
Candelabra (E12)
Candelabra bulb holders have a smaller Edison screw base and are often found in chandeliers and decorative fixtures. Their aesthetic appeal adds elegance to lighting designs, but they have a limited wattage capacity, which restricts the types of bulbs that can be used.
T8 and T5
T8 and T5 bulb holders are designed for fluorescent lights, with T5 being a slimmer alternative to T8. These holders are commonly used in commercial and industrial settings due to their energy efficiency and long operational lifespan. However, they require a ballast for operation, which can complicate installation.
E26/E27
The E26 and E27 holders are standard medium bases used in most household lamps. Their widespread availability and compatibility with a variety of bulbs make them a go-to choice for residential lighting. While they can be bulky, their functionality outweighs this drawback for many users.
G9
G9 holders are compact bi-pin bases that are perfect for decorative fixtures and small lamps. Their space-efficient design allows for versatile applications. However, they are limited in wattage, which may restrict the types of bulbs used.
