3V 1W Flexible LED Filament one side connection 2mm diameter 300mm length – Warm white

3V 1W Flexible LED Filament one side connection 2mm diameter 300mm length – Warm white provides a stunning, vintage-inspired lighting solution that combines modern high-efficiency LED technology with high mechanical flexibility. This 300mm long filament emits a soft, inviting 2700K warm white glow, making it an ideal choice for decorative lighting, 3D printing projects, and bespoke Edison-style bulb restorations. Furthermore, the unique one-side connection design significantly simplifies cable management, as users only need to route power to a single end of the flexible strip. Consequently, designers can weave, bend, and wrap the filament into complex shapes without the clutter of dual-ended wiring. Therefore, this high-quality flexible LED component serves as a versatile tool for hobbyists and professional lighting designers seeking a distinct, linear aesthetic for their custom illumination projects.

Key Features:

• High Flexibility: The silicon-based substrate allows the filament to bend and twist easily into intricate patterns without damaging the internal LED string.
• One-Side Connection: This innovative design places both positive and negative terminals on one end, which greatly streamlines the installation process in tight spaces.
• Warm White Glow: The filament delivers a classic 2700K color temperature, offering a cozy and high-end atmosphere suitable for premium decorative fixtures.
• Consistent Brightness: Additionally, the densely packed LED chips ensure a uniform light output along the entire 300mm length without visible dark spots.
• Low Power Consumption: Operating at just 1W, this filament generates minimal heat while providing significant luminous intensity.
