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

3V 100mA Edison Bulb LED Filament 38mm – Purple provides a unique, vintage aesthetic by combining modern LED efficiency with the classic look of a traditional carbon filament. This 38mm flexible filament emits a vibrant purple hue, making it an excellent choice for decorative lighting projects and DIY electronics. Furthermore, its low voltage requirement allows for easy integration with battery-powered circuits and low-power microcontrollers. Consequently, hobbyists and designers can achieve high-impact visual effects without the complexity of high-voltage wiring. Therefore, you can use this filament to create custom lamps, wearable art, or atmospheric displays that stand out with a professional finish.

Key Features:

• Vibrant Purple Output: Emits a rich, distinct purple light that adds a premium decorative touch to any lighting fixture.
• Energy Efficient: Consumes significantly less power than traditional incandescent bulbs while maintaining a bright, uniform glow.
• Flexible Design: The 38mm length features a flexible substrate, allowing for slight bending and creative positioning within custom enclosures.
• Low Heat Emission: Generates minimal heat during operation, which ensures safety when used in enclosed or heat-sensitive DIY projects.
• 360-Degree Illumination: Provides a full angle of light distribution, mimicking the omnidirectional glow of classic Edison bulbs.

Pinout and Wiring:

• Anode (+): Identified by a small hole or marking on the metal end-cap. Connect this to the positive 3V terminal.
• Cathode (-): The opposite unmarked metal end-cap. Connect this to the ground or negative terminal.
• Wiring Note: However, always use a current-limiting resistor if your power supply exceeds 3.0 V to prevent over-driving the LEDs.
