Product Specifications

The T3 wire halogen lamp (12V, 0.45W) is a compact type of halogen bulb, commonly used in scenarios such as indicator lighting. Below is a detailed introduction to it:

• Specifications and Parameters:

  • Voltage and Power: It operates at a voltage of 12V with a power of 0.45W, which is a low-power bulb with relatively low power consumption.

  • Dimensions: "T3" indicates the bulb's form factor. Here, "T" stands for the cylindrical shape of the bulb, and "3" refers to its diameter of 3/8 of an inch (approximately 9.5 millimeters), making the overall size quite compact.

  • Luminous Principle: It utilizes the chemical reaction between halogen gases (such as iodine, bromine, etc.) and the tungsten filament at high temperatures. This reaction causes the evaporated tungsten to reattach to the filament, thereby extending the filament's service life while emitting bright light.

• Structural Features:

  The bulb is equipped with two wires at its base. These two wires are electrode leads, which are used to connect to a power source and supply electrical energy to the bulb for illumination. This wire-integrated design facilitates direct connection to the circuit without the need for an additional lamp holder, simplifying the installation process.

• Application Scenarios:

  Thanks to its low voltage, low power consumption, and compact size, it is typically used in automotive instrument lights, indicator lights, night lights, indicator lights for various electronic devices, as well as in miniature lamps requiring low-power illumination or model lighting.

• Advantages:

  Compared with traditional incandescent lamps, halogen lamps have higher luminous efficiency, capable of providing relatively bright light at a lower power rating. Additionally, they produce a warm color temperature with soft light and excellent color rendering properties, which can restore the true colors of objects more accurately.

• Disadvantages:

  Although more efficient than incandescent lamps, they are still relatively power-hungry when compared with LED lamps, and their service life is relatively short, generally ranging from several hundred to one thousand hours. Furthermore, halogen lamps generate relatively high temperatures during operation, so care should be taken to avoid direct contact to prevent scalding.
