- Specifications: tension: AD; Input Voltage: 12 V

Rigid lighting solution for decorative projects, illuminated signs and custom fixtures at 12V, emits uniform red light at 360 degrees for a homogeneous effect from any direction. The construction on a rigid support with silicone coating offers protection, pleasant diffusion and resistance to light shocks. Low consumption and minimal heat release, quick connection through metal ends.
LED Rigid Filament 38 mm is an efficient and durable lighting solution, designed for applications where a fixed and stable shape is required. The filament is made on a rigid support and is coated in silicone, which provides additional protection, uniform light diffusion and increased resistance to light shocks.
