What is MR20 Socket?

MR20 socket is a type of socket commonly used in lighting fixtures. It is designed specifically for MR20 halogen bulbs, which are small, low-voltage bulbs commonly used in track lights, recessed lights, and landscape lighting. The MR20 socket provides the electrical connection between the bulb and the fixture, allowing the bulb to receive power and illuminate the surrounding space.


The MR20 socket consists of a base with two pins that fit securely into the corresponding slots on the bulb. The pins are typically made of metal, such as brass or copper, which allows for efficient conductivity and ensures a stable connection. The base of the socket is typically made of plastic or ceramic, which provides insulation and protects against electrical shocks.

One of the key advantages of the MR20 socket is its compact size, making it suitable for small lighting fixtures. The MR20 bulb itself is also small, typically measuring 20mm in diameter, which allows for precise and focused lighting. This makes MR20 bulbs and sockets popular for accent lighting, highlighting specific areas or objects in a room or outdoor space.


When installing or replacing MR20 bulbs, it is important to ensure compatibility between the bulb and socket. The MR20 socket is specifically designed for MR20 bulbs and may not be compatible with other bulb types. It is also important to handle the bulbs with care, avoiding touching the glass surface with bare hands, as the oils from the skin can cause premature bulb failure.


Overall, the MR20 socket is a crucial component in lighting fixtures that use MR20 bulbs. Its compact size, precise connection, and versatility make it a popular choice for a variety of lighting applications. Whether used in residential or commercial settings, MR20 sockets and bulbs provide efficient and focused lighting solutions.
