Top 3 LED Spotlights Distribution Designs and Features


LED spotlights are not all created equal. The term ‘spotlight’ refers to a tight light beam, designed for long-distance or intense illumination.

It is important to highlight that, within this definition, LED spotlights can vary greatly. In fact, lighting manufacturers may classify LED spotlight distribution in three main groups: Type I, Type II and Type III.

Read on to learn more about these LED spotlight distribution classifications.

Type I

Type I provides a two-lateral configuration, with a lateral width of 15 degrees in the cone. This helps the unit achieve robust candlepower ratings. The LED diodes are positioned away from each other, producing a wide-version of a spotlight beam. Type I LED distribution is ideal for illuminating paths and public walkways.

Type II

Type II is like Type I, but offers slightly wider light distribution for larger spaces. Taking on a lateral width of 25 degrees, this option is suitable for roadside locations and side streets. The LED light distribution can be applied to elevated positions, as long as the required width during illumination does not exceed 1.75 times the height of the luminary.

Type III

This type of LED distribution is the widest out of the three, with a lateral width of 40 degrees. The angle of the units ensures proper illumination, when mounted at heights not exceeding 2.75 times the measurement of the target. Taking this into consideration, this type of light distribution is mostly used for side-lighting on roadways.

Lastly, other types of LED light distribution provide wider lighting conditions, such as Type IV. Furthermore, some variants emit full, circular light distribution (Type V), like an LED strobe lamp. This type of unit can be found in commercial parking lots. A square version of Type V light distribution is Type VS, which promotes even light intensity at various angles.
