With LED track lights you have the option to highlight specific items (spot lighting) or wall wash bigger areas of a room (flood lighting). These results can be achieved by using different beam angles, and are perfect for art galleries where you have a number of objects of different shapes, sizes and colours.
Spotlighting is used when, for example, you have a smaller art piece on which you want to focus attention. You can use narrow beam angles on the lights in order to direct the light onto specific items. To wash an area, like an entire wall, install wider beam angles on a number of the lights to create broad and even illumination across the wall.
Fixed beam angles can be used for gallery spaces when the art items are all of similar shapes and sizes. Larger paintings, for example, appear best when they are wall washed.
