Halo Compatible Track Lighting | One of the things you frequently learn about LED lights, is their beam angle is narrower compared to the old fashion incandescent lights, as well as compared to the newer CFLs.
What can this mean and it is it an issue?
The beam angle could be the angle from which light is directed in the bulb. So a small angle of 20 degrees would be right for a place light, focusing light on only one small area. If you want more general lighting, spreading light on the whole room, a greater angle of perhaps 90 degrees would be preferred. In most domestic lighting situations beam angles of 30-45 degrees are sufficient to light an area comfortably.

The idea that LEDs have narrow beam angles stems in the older technology LEDs which are indeed suitable for focused light in a narrow area. Today this really is will no longer true. New technology now ensures that LED lights are available in a wide array of beam angles, from narrow spotlights to wider general lighting. Some LEDS can be purchased in a array of beam angles from 15, 30, 40, 45, 60, 90, to 120 degrees. What this means is there is a lots of choice available on the market, sometimes so much choice which it gets confusing to the buyer. You can will no longer just grab a bulb in the supermarket shelf. There are decisions to become made!
