Track Lighting Basics | One of the things you often learn about LED lights, is that their beam angle is narrower than the old fashion incandescent lights, as well as than the newer CFLs.
What creates this change mean and is it an issue?
The beam angle will be the angle of which light is directed through the lamp. So a smaller angle of 20 degrees could be appropriate for a place light, focusing light on only one small area. If you want more general lighting, spreading light on the whole room, a bigger angle of perhaps 90 degrees could be preferred. In most domestic lighting situations beam angles of 30-45 degrees are sufficient to light a place comfortably.

The concept that LEDs have narrow beam angles stems through the older technology LEDs that have been indeed suitable for focused light in the narrow area. Today this can be no more true. New technology now signifies that LED lights are available in the wide selection of beam angles, from narrow spotlights to wider general lighting. Some LEDS are available in the selection of beam angles from 15, 30, 40, 45, 60, 90, to 120 degrees. What this means is that there is a large amount of choice in the marketplace, sometimes so much choice that it gets confusing for the buyer. You can no more just grab a lamp through the supermarket shelf. There are decisions to get made!
