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

3V 100mA Edison Bulb LED Filament 38mm – Green provides a vintage aesthetic combined with modern, energy-efficient LED technology for creative lighting projects. This flexible 38mm filament emits a vibrant green glow, effectively replicating the classic look of traditional carbon-filament Edison bulbs. Furthermore, its low voltage requirement and high brightness make it an excellent choice for portable DIY electronics and decorative displays. Consequently, hobbyists can create stunning visual effects without the heat or fragility associated with glass incandescent bulbs. Therefore, you should consider this versatile component for any project where a retro-industrial feel or unique ambient lighting is the primary goal.

Key Features:

• High Efficiency: The LED technology delivers a brilliant green output while consuming significantly less power than vintage incandescent alternatives.
• Flexible Design: This filament features a semi-flexible substrate, allowing for slight curves and creative orientations in custom lamp housings.
• Low Heat Emission: Unlike traditional filaments, this LED version stays relatively cool during operation, which improves safety and broadens material compatibility.
• Uniform Light Distribution: The 360° light emission ensures that the green glow spreads evenly in all directions without dark spots.
• Battery Compatible: Its 3V operating voltage aligns perfectly with common power sources like AA batteries or CR2032 cells.

• Forward Voltage (V_F): 2.8 V to 3.2 V (Standard 3V Nominal)
• Forward Current (I_F): 100 mA (Maximum Recommended)
• Power Consumption: ≈ 0.3 W
• Luminous Color: Green (520 nm − 530 nm Peak Wavelength)
• CRI (Color Rendering Index): ≥ 80 (For high-quality color reproduction)
• Operating Temperature: −10°C to +50°C

Mechanical Specifications:

• Substrate Material: Flexible Polymer/Ceramic Hybrid
• Encapsulation: High-transparency Green Silicone
• Connector Type: Solderable Metal End-Caps
• Durability: Highly resistant to vibration and minor mechanical shock.

Dimensions:

• Total Length: 38 mm
• Filament Diameter: ≈ 2.0 mm
• End-Cap Width: ≈ 3.0 mm
• Weight: ≈ 0.1 g

Pinout and Wiring:

• Positive Terminal (+): Identified by a small hole or “+” marking on the metal end-cap; connect this to the positive supply.
• Negative Terminal (−): Connect this end-cap to the ground or negative side of the power source.
• Wiring Note: However, you must always use a series resistor if your supply voltage exceeds 3.2V to prevent thermal runaway or permanent damage to the LED dies.
