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

3V 100mA Edison Bulb LED Filament 38mm – Blue offers a unique blend of vintage aesthetics and modern semiconductor efficiency, providing a vibrant blue glow for decorative lighting projects. This flexible LED filament measures 38 mm in length and operates on a low-voltage 3V supply, making it perfectly compatible with battery-powered circuits or microcontroller outputs. Furthermore, the specialized phosphor coating ensures a uniform light distribution along the entire length of the filament. Consequently, hobbyists and designers can create stunning “Edison style” visual effects in compact DIY lamps, cosplay props, or scale models without the fragility and heat of traditional incandescent bulbs. Therefore, you should choose this blue LED filament to achieve a striking, professional finish in any custom illumination project.

Key Features:

• High-Efficiency LED Technology: The filament utilizes a series of micro-LED chips encapsulated in a flexible, transparent substrate to maximize light output while minimizing energy consumption.
• Vibrant Blue Emission: It delivers a saturated blue wavelength, providing a distinct decorative contrast compared to standard warm-white filaments.
• Flexible Construction: You can slightly bend the filament to fit specific housings or artistic shapes, although you must take care to avoid sharp kinks.
• Low Power Operation: The device draws only 100 mA at 3 V, allowing for extended runtime in portable or solar-powered applications.
• Minimal Heat Generation: However, unlike traditional filaments, this LED version stays relatively cool during operation, permitting use in enclosed or heat-sensitive environments.

Technical Specifications:

• Operating Voltage: 2.8 V to 3.2 V DC
• Rated Current: 100 mA
• Power Consumption: ≈ 300 mW
• Color: Blue
• Luminous Intensity: ≈ 80 to 100 LM/W (Efficiency rating)
• Operating Temperature Range: −10°C to +60°C

Mechanical Specifications:

• Substrate Material: Flexible Polymer
• Terminal Material: Gold-plated or Tinned Copper Pads
• Flexibility: Semi-flexible (Minimum bend radius ≈ 10 mm)
• Durability: Highly resistant to impact and vibration compared to glass-encased bulbs.

Dimensions:

• Total Length: 38 mm
• Filament Diameter: ≈ 1.5 mm to 2.0 mm
• Terminal Size: ≈ 2.0 mm x 2.0 mm

Pinout and Wiring:

• Positive Terminal (+): Identify the anode by looking for the small hole or specific marking on the metal tab; connect this to the 3V positive rail.
• Negative Terminal (−): Connect the unmarked terminal tab to the ground (0V) of your power source.
• Wiring Note: Always use a current-limiting resistor if your supply voltage exceeds 3.2 V to prevent thermal runaway and damage to the LED chips.

Commonly Used in:

• Custom DIY Lighting: Creating modern “steampunk” or futuristic desk lamps with a blue aesthetic.
• Scale Modeling: Providing realistic, low-heat interior lighting for architectural models or train sets.
• Signage: Building eye-catching glowing text or outlines for indoor displays.

Applications:

• Battery Powered Decor: Excellent for portable night lights or event table centerpieces due to the low 3V requirement.
• Cosplay and Prop Design: Integrating into wearable tech where weight and heat management are critical factors.
• Visual Indicators: Serving as high-visibility status indicators in creative industrial control panels.

Equivalent Models:

• Flexible LED Filament 3V 300mA: A higher power version for increased brightness requirements.
• Filament LED 38mm (Green/Red): Functionally identical models available in different monochromatic wavelengths.
• COB LED Strip 3V: A similar low-voltage light source, however, it lacks the thin “wire” aesthetic of the Edison filament.
