## Description

Compact solution for decorative lighting and commercial applications at 12V, with rigid construction on a stable support and silicone coating for protection and uniform diffusion. Provides 360 degrees white light, low consumption with current below 45mA and emits very little heat, ideal for custom bulbs, shop windows and illuminated signs.
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.
It emits light at 360 degrees, ensuring homogeneous illumination from all directions.
It operates at 12V and has a low power consumption with a current of less than 45mA, generating very little heat. It is safe to use, energy efficient and offers a long lifespan, making it ideal for decorative lighting projects and commercial or industrial applications.
IMPORTANT! Use ONLY with the power source in constant mode and MANDATORY set to a current lower than 45mA! Use with higher current will lead to overheating and premature degradation of the LED!
Bending the filament will cause it to BREAK! THE FILAMENT IS NOT FLEXIBLE!

Use:
The rigid filament LED is used in decorative lighting fixtures, custom bulbs, illuminated signs and other applications where 12V power is required. It is mounted in a fixed position, respecting the polarity and supply voltage. The silicone coating helps protect the filament and uniform light dissipation, contributing to safe and reliable operation in the long term.
The filament has metal ends for connection. ATTENTION : The plus is easily recognized by the fact that it has a hole in the connector.
IMPORTANT! Use ONLY with the power source in constant mode and MANDATORY set to a current lower than 300mA! Use with higher current will lead to overheating and premature degradation of the LED!
Bending the filament will cause it to BREAK! THE FILAMENT IS NOT FLEXIBLE!
