In this article, we will delve into the details of the 5mm Bullet LED, exploring its features, benefits, and applications across different sectors.

What is a 5mm Bullet LED?

The 5mm Bullet LED is a type of surface mount device (SMD) LED that is known for its small size and cylindrical shape. It measures just 5mm in diameter, making it one of the smallest LED packages available on the market. Despite its tiny size, the 5mm Bullet LED is capable of producing a significant amount of light, thanks to its high luminous efficiency.

Design and Specifications

The 5mm Bullet LED is designed with a clear, diffused, or opal lens that provides a smooth and uniform light distribution. This makes it ideal for applications where a diffused light source is required. The LED is typically available in a variety of color temperatures, including warm white, cool white, and RGB (red, green, blue), allowing users to choose the perfect light for their specific needs. The specifications of a 5mm Bullet LED can vary depending on the manufacturer, but common features include: - Forward voltage: Typically between 2.8V and 3.2V - Forward current: Varies from 20mA to 30mA - Luminous intensity: Up to 1200 lumens - Color rendering index (CRI): Typically around 80 to 90
