Product Specifications

The W5WNB 12V 5W halogen lamp, featuring Natural Blue color and a W2.1×9.5d base, is a low-voltage dedicated light source focusing on cool-toned identification and ambient lighting. In the model designation, W5W corresponds to the core electrical specifications: a rated voltage of 12 volts and a rated power of 5 watts; the suffix NB is the abbreviation for Natural Blue, specifically referring to the natural blue cool light it emits, which is different from conventional warm white light or warning amber light; W2.1×9.5d is the specification of the standardized pin-type base, where "W2.1" indicates the pin width of the base is 2.1 millimeters, and "9.5d" indicates the pin depth (length) is 9.5 millimeters. It adopts a universal snap-in pin structure, which can be directly compatible with standardized slot lamp holders, enabling plug-and-play installation and replacement without welding.

Adopting halogen cycle technology, this lamp can effectively inhibit the evaporation loss of the tungsten filament. Compared with ordinary colored coated incandescent lamps, it has higher luminous efficiency and stronger color stability. The natural blue light has a color temperature usually ranging from 8000K to 10000K, with a prominent cool-toned texture, making it suitable for lighting scenarios that require eye-catching identification or special ambiance. Its 12V low-voltage power supply ensures high safety, especially suitable for enclosed and easily accessible scenarios. During use, it should be matched with a 12V DC or regulated AC power supply to avoid overvoltage operation; during installation and replacement, it is strictly forbidden to directly touch the glass tube with hands to prevent local overheating caused by residual fingerprint grease, which may shorten the service life of the lamp. It is widely used in scenarios such as car interior ambient lights, identification indicator lights for precision instruments, cool light decorative lights for small display devices, and status indicator lights for some industrial equipment.
