3V 100mA Edison Bulb LED Filament 38mm – Pink

3V 100mA Edison Bulb LED Filament 38mm – Pink offers a distinctive blend of vintage aesthetics and modern semiconductor technology, providing a vibrant pink glow for decorative and creative lighting projects. This flexible LED filament measures 38mm in length and mimics the classic look of traditional carbon filaments found in early incandescent bulbs. Furthermore, the low-voltage design allows for safe operation using standard 3V power sources, such as lithium-cell batteries or regulated power supplies. Consequently, hobbyists and engineers can easily integrate these filaments into custom light fixtures, wearable electronics, and architectural models without the heat or fragility associated with glass bulbs. Therefore, this component serves as the perfect choice for those seeking to combine retro style with high-efficiency LED performance.

Key Features:

• Vibrant Pink Output: The high-quality phosphor coating produces a consistent and saturated pink hue, ideal for specialized mood lighting and artistic displays.
• 360-Degree Illumination: The linear design ensures that light radiates in all directions, creating a seamless glow without the harsh directional shadows of standard SMD LEDs.
• Energy Efficient: This filament consumes significantly less power than traditional bulbs while maintaining a high lumen output.
• Flexible Construction: The substrate allows for slight bending, however, users must handle it carefully to avoid damaging the internal diode string.
• Minimal Heat Generation: Unlike incandescent wire, the LED structure remains relatively cool during operation, which improves safety in enclosed decorative housings.
