3V 100mA Edison Bulb LED Filament 38mm – Warm White

3V 100mA Edison Bulb LED Filament 38mm – Warm White provides a perfect blend of vintage aesthetics and modern semiconductor efficiency for your lighting projects. This 38mm flexible LED filament mimics the warm glow of traditional tungsten coils while consuming significantly less power. Furthermore, the chip-on-glass (COG) technology ensures a uniform, 360° light distribution without the harsh hotspots typical of standard SMD LEDs. Consequently, designers can create elegant, retro-inspired lamps and decorative displays that remain cool to the touch. Therefore, you should utilize this high-efficiency Warm White filament whenever your application requires a sophisticated, linear light source with a wide viewing angle.

Key Features:

• 360° Light Emission: The filament structure emits light from all sides, ensuring a full and even glow similar to a traditional vacuum-sealed bulb.
• Low Voltage Operation: This component runs on a nominal 3V supply, making it exceptionally compatible with battery-powered circuits and portable electronics.
• High Color Rendering: It delivers a crisp Warm White light that enhances the visual clarity of illuminated objects and surrounding environments.
• Energy Efficient: The LED technology converts energy into light with minimal heat generation, which extends the lifespan of the decorative housing.
• Compact Form Factor: Its 38mm length allows for easy integration into small scale models, dollhouses, and custom artistic installations.

Technical Specifications:

• Operating Voltage: 2.8 V to 3.2 V DC (Typical 3.0 V)
• Forward Current (I_F): 100 mA
• Power Consumption: ≈ 300 mW
• Color Temperature: 6000 K to 6500 K (Warm White)
• Luminous Flux: ≈ 25 to 30 Lumens
• Lifespan: ≥ 20,000 hours (When operated within rated parameters)

Mechanical Specifications:

• Substrate Material: Ceramic or Glass core with polymer coating.
• Encapsulation: Transparent Silicone.
• Flexibility: Semi-rigid (Handle with care to avoid cracking the internal LED string).
• Terminal Type: Metal end-caps for soldering.

Dimensions:

• Total Length: 38 mm (±1 mm)
• Diameter: ≈ 1.5 mm to 2.0 mm
• Effective Lighted Length: ≈ 30 mm

Pinout and Wiring:

• Positive Terminal (+): Usually indicated by a small hole or notch in the metal end-cap. However, you should always test with a multimeter at low current to verify polarity.
• Negative Terminal (−): The opposite metal end-cap.
• Wiring Note: Always use a current-limiting resistor if your supply voltage exceeds 3.0 V to prevent thermal runaway and permanent damage.
