Product Specifications

The 12V 1.2W halogen lamp (marked as W1.2W) with a base specification of W2.0×4.6D is a low-voltage, low-power halogen light source designed for precision applications. Among the specifications, W1.2W is the power identification code of the lamp, corresponding to a rated power of 1.2 watts and a rated voltage of 12 volts; W2.0×4.6D refers to the model specification of its dedicated base, representing the key dimensional parameters of the base—usually "W2.0" indicates that the width of the base is 2.0 millimeters, and "4.6D" indicates that the depth (or length) of the base is 4.6 millimeters. This type of base is mostly a small snap-in or pin-type structure, suitable for dedicated card slots or sockets, which is different from the wire lead-out design and conventional black base design.

Relying on halogen cycle technology, this lamp can effectively slow down the evaporation loss of the tungsten filament. Compared with ordinary incandescent lamps of the same power, it has the advantages of higher luminous efficiency, stable color temperature (warm white light ranging from 2800K to 3200K), and excellent color rendering index (CRI≥95), which can accurately restore the true color of the illuminated object. The design of its special-specification base greatly improves the installation firmness and compatibility. It can be directly inserted into the matching socket to complete wiring without welding operations, featuring high installation efficiency and low contact resistance to ensure stable power supply.

During use, it needs to be matched with a 12V DC or regulated AC power supply, and overvoltage use is strictly prohibited. Meanwhile, avoid direct contact with the glass tube with hands to prevent local overheating caused by fingerprint grease and shorten the service life of the lamp. It is widely used in low-power scenarios with strict requirements on installation space and compatibility, such as backlighting of micro-instruments, light sources of precision sensors, indicator lights of small medical testing equipment, and micro interior lighting of automobiles.
