China Neodymium And Ferrite Magnets Manufacturer & Supplier 
Magnetic suction lighting fixtures have seen widespread adoption in recent years across residential and commercial lighting applications. Utilizing magnetic adhesion, these fixtures offer effortless installation and removal, eliminating the hassles associated with traditional mounting methods. As the core component of magnetic lighting systems, the type and performance of magnets directly impact fixture stability and user experience. Common magnet configurations for magnetic suction lighting include LED magnetic columns, iron casings paired with circular magnets, and iron casings paired with rectangular magnets.
LED Magnetic Column
It resembles a pillar in shape, composed of a magnetic column, magnets, and screws. The magnets are primarily made of neodymium, providing powerful magnetic force to secure light strips, LED panels, drivers, displays, and other components.
Steel Shell + Round Magnet
The steel shell and round magnet are a common combination in magnetic-attachment lighting fixtures. The iron shell concentrates the magnetic field, enhancing magnetic efficiency and thereby strengthening the round magnet's adhesive force. Due to its simple structure and broad applicability, the round magnet is widely used in various magnetic-attachment lighting fixtures, particularly in small fixtures and scenarios requiring convenient installation.
Steel Shell + Rectangular Magnet
The steel shell + rectangular magnet combination is typically used in lighting fixtures with higher magnetic force requirements, especially those needing to support heavier loads. The rectangular magnet design provides a larger contact area, enabling more stable adhesion across broader metal surfaces. The iron shell further enhances magnetic force and ensures more uniform magnetic field distribution.
The image below shows a combination of a rectangular magnet and a recessed iron shell, also known as a channel magnet or a strong magnet assembly.
The above covers the three most common magnet types used in magnetic lighting fixtures. If you require bulk purchases of these magnets, please provide specific dimensions for a price quote.
