Product Specifications

The PGJ13-base 12V27W Type 889 halogen lamp is a halogen light source widely used in professional lighting applications. Its key feature is the use of a PGJ13 two-pin base, which ensures secure installation in luminaires and reliable electrical contact, making it particularly suitable for environments prone to vibration or frequent switching.

This lamp operates at a rated voltage of 12 volts with a power of 27 watts, falling into the category of low-voltage, high-efficiency lighting. The model number "889" is a common industry identifier, facilitating easy recognition and replacement for users. The halogen lamp operates on the principle of the halogen cycle, where halogen gas inside the bulb effectively slows the evaporation of the tungsten filament. This helps maintain high luminous flux output throughout its lifespan while offering stable light color and excellent color rendering (close to 100), accurately reproducing the colors of illuminated objects.

This type of bulb is commonly found in low-voltage lighting systems, such as accent lighting for display windows, jewelry counters, museum exhibit lighting, high-end residential decorative lights, and some projection instruments. Its advantages include instant illumination, immediate full brightness, concentrated light output, and ease of optical control. It is important to note that due to its high operating temperature, direct contact with the glass bulb with bare hands must be avoided during installation to prevent oil residues from causing localized overheating and damage. When selecting this lamp, it is essential to ensure the lighting fixture's circuit is compatible with 12V low-voltage input, and it typically requires use with an appropriate electronic or magnetic transformer.
