LED spotlights have become increasingly popular in recent years due to their energy efficiency and versatile applications. When it comes to purchasing LED spotlights, understanding the various specifications and size options available is crucial. This comprehensive guide will provide you with all the necessary information to make an informed decision.

1. Wattage: LED spotlights come in different wattage options, ranging from 3W to 20W. The wattage determines the brightness and energy consumption of the spotlight. Higher wattage usually indicates stronger brightness but also higher energy consumption.

2. Lumen Output: The lumen output measures the total amount of visible light produced by the spotlight. It is an important factor to consider when choosing a LED spotlight. The lumen output typically ranges from 200 to 2000 lumens, depending on the wattage and design of the spotlight.

3. Beam Angle: The beam angle determines the spread of light produced by the spotlight. A narrow beam angle, such as 15 degrees, creates a concentrated beam of light ideal for highlighting specific objects or areas. A wider beam angle, such as 60 degrees, provides a broader coverage of light suitable for general illumination.

4. Color Temperature: LED spotlights are available in various color temperatures, measured in Kelvin (K). The color temperature determines the tone of the light emitted by the spotlight. Lower Kelvin values (around 2700K) produce warm white light, while higher Kelvin values (above 5000K) produce cool white light.

5. CRI (Color Rendering Index): The CRI measures the ability of a light source to accurately render colors compared to natural light. A higher CRI value indicates better color reproduction. Typically, LED spotlights have a CRI above 80, ensuring vibrant and true-to-life colors.

Now that we have discussed the essential specifications, let's move on to the size comparison table, which will help you visualize the different dimensions available:
