38mm Filamemt ceramic 3v led light low current high brightness natural multiple color

The 38mm Ceramic LED Filament 3V is a compact linear lighting component designed for decorative illumination, electronic experiments, and custom-built lighting products. It uses LED chip technology on a rigid ceramic substrate to produce a continuous filament-like glow.

Operating at approximately 3V DC, this LED is suitable for low-voltage circuits and battery-powered lighting projects when operated within its specified current range. Its ceramic construction supports heat dissipation, while the 360-degree light-emitting design helps distribute illumination around the filament.

Available in multiple colors, it can be used to create different lighting effects for decorative fixtures, miniature models, custom lamps, and DIY electronics.

Features

• 38mm Filament Design: Compact elongated shape for custom lighting installations.

• 3V Low-Voltage Operation: Suitable for compatible low-voltage DC circuits.

• High-Brightness Illumination: Produces a bright, continuous filament-style glow.

• Low-Current Design: Requires relatively low operating current compared with many conventional lighting solutions.

• Ceramic Substrate: Provides a rigid base with good heat-dissipation characteristics.

• 360-Degree Light Emission: Helps distribute light around the filament.

• Multiple Color Options: Available in different colors for decorative and functional lighting.

• COB LED Technology: Combines multiple LED chips into a compact linear light source.

Applications

• DIY Edison-style LED bulbs

• Decorative lamps and lighting fixtures

• Miniature architectural models and dollhouses

• RC model lighting and custom projects

• Camping lanterns and portable lights

• LED art, crafts, and display decorations

• Electronics learning and experimentation

• Custom low-voltage lighting circuits

How to Use

1. Identify the positive (+) and negative (-) terminals before connecting the LED.

2. Use a regulated DC supply appropriate for the LED's specified forward voltage.

3. Add a suitable current-limiting resistor or constant-current driver.

4. Connect the positive and negative terminals with correct polarity.

5. Test the LED at its rated current before installing it inside an enclosure.

6. Provide suitable space for heat dissipation during continuous operation.

Important Notes

• This is a rigid ceramic filament and should not be bent.

• Do not connect it directly to a higher-voltage battery or power supply without appropriate current limiting.

• A single-cell 3.7V Li-ion/LiPo battery may exceed the LED's recommended operating voltage; use a suitable current-control circuit.

• Operating current varies by color and product version. Check the specific variant before selecting a resistor or driver.

• Handle the ceramic body and solder terminals carefully to prevent cracking or damage.

• Avoid exceeding the recommended forward current, as excessive current can reduce lifespan or damage the LED.
