Product Specifications

The 12V 0.56W T4 wire halogen lamp with two leads is a small tubular low-voltage halogen light source. The term "T4" indicates a tube diameter of 4/8 inch (12.7mm), and "wire" refers to its lead - out wire design (without a standard lamp base, with two power - supply wires at the bottom). Its core parameters are a rated voltage of 12 volts and a rated power of 0.56 watts. It adopts the halogen cycle principle to inhibit the evaporation of the tungsten filament. Compared with ordinary incandescent lamps of the same specification, it has higher luminous efficiency, a longer service life, and a more stable color temperature (usually about 2700K - 3000K, presenting warm white light). Its Color Rendering Index (CRI) can reach over 95, which can accurately restore the true color of objects.

The two wires of this lamp can be directly welded or connected to the power supply circuit through terminal blocks without a special lamp base, making it suitable for small installation spaces. It is commonly used in low - power precision scenarios such as backlighting of instruments and meters, light sources of micro - sensors, indicator lights of medical testing equipment, and lighting of small optical equipment. When in use, it is necessary to match a 12V DC or AC regulated power supply to avoid damage caused by overvoltage. Meanwhile, avoid direct contact with the glass shell with hands to prevent local overheating caused by grease from shortening the service life.
