3V 100mA LED Filament 45mm COB Edison Bulb Filament
[COB LED] The 3V 100mA LED Filament 45mm is a flexible COB LED light source designed for decorative lighting, Edison bulb restoration, DIY lamps, and creative illumination projects. Available in a variety of colors, it delivers bright and uniform light output while maintaining low power consumption. In addition, the filament provides 360-degree illumination, closely replicating the appearance of traditional Edison-style incandescent filaments. As a result, it is widely used in decorative bulbs, custom lighting fixtures, model lighting, art installations, and creative electronics projects. Because of its flexible substrate design, the filament can be slightly bent to fit custom enclosures and unique lighting arrangements. Furthermore, it produces minimal heat during operation, making it safe for compact and enclosed lighting applications. The advanced COB LED structure ensures consistent brightness, excellent efficiency, and long service life. Moreover, the solderable metal terminals allow quick integration into DIY electronics and lighting projects. 🔹 Key Features Available in multiple colors Bright and uniform light output COB LED filament design Low power consumption Excellent energy efficiency Minimal heat generation 360° illumination pattern Lightweight and compact structure Easy solderable metal terminals Long operational life 🔹 Technical Specifications Product Type: COB LED Filament Operating Voltage: 2.8V to 3.2V DC Rated Voltage: 3V DC Forward Current: 100mA (Maximum) Power Consumption: Approximately 0.3W Brightness: Approximately 80–100 Lumens per Watt Filament Type: COB (Chip-on-Board) LED Filament Base Material: Flexible Polymer Substrate Connection Type: Solderable Metal End-Caps led Length: 45mm Total Length: 55mm Filament Diameter: Approximately 2.0mm Terminal Size: Approximately 2mm × 2mm Weight: Less than 1g Available Colors: Warm White, Cool White, Red, Blue, Green (subject to availability) 🔹 Mechanical Specifications Filament construction Durable polymer substrate Highly resistant to mechanical shock Lightweight design Easy soldering connection terminals Suitable for custom lamp and lighting assemblies 🔹 Applications This LED filament is suitable for: Edison bulb repair and replacement Decorative LED lamps Custom lighting fixtures Battery-powered lighting projects Art installations Scale models and dioramas Display and showcase lighting Wearable electronics DIY electronics projects Creative lighting applications 🔹 Package Includes 1 × 3V 100mA LED Filament 38mm (Selected Color)
Crocodile Alligator Clip 50 mm Black and Red
Description: An alligator clip, also called a spring clip, creates a temporary electrical connection using a simple mechanical design.It gets its name because the jaws resemble an alligator or crocodile’s mouth, opening and closing to grip objects securely.The clip works like a spring-loaded clothespin that uses tapered, serrated jaws to hold wires or metal parts tightly.A spring pushes the jaws together, allowing the clip to grip objects and maintain a reliable electrical connection.Manufacturers design these clips for electronics testing, enabling quick connections without soldering or permanent joints.One jaw usually connects to a wire by crimping or soldering for efficient current transfer.Some clips use a bent jaw forming the inner contact of a 15 mm to 4 mm female banana jack.This design allows a fast, non-permanent connection between test circuits and laboratory instruments.A plastic cover or boot surrounds the clip to prevent short circuits and protect users from accidental shocks.Engineers and students use these clips widely in testing, prototyping, and educational experiments. Applications: Technicians use small clips (15 mm–40 mm) in electrical laboratories, schools, and college labs for quick test connections.Large clips, called automotive clips or battery clamps, use solid copper for low resistance and strong current flow.Users connect these large clips with thick insulated copper cables between automobile batteries or heavy electrical systems.Hobbyists and professionals rely on these clips for safe, reusable, and efficient electrical connections. Product Example: Check the Crocodile Alligator Clip 50 mm – Red and Black, made from durable stainless steel with a protective plastic shroud.Its spring-loaded jaws open wide to grip different wire sizes securely during testing or circuit connection.The serrated teeth ensure a strong, slip-free grip that maintains stable electrical contact during operation. Package Includes: 1 × Crocodile Alligator Clip 50 mm (Black and Red)
