Pierced Tin Lighting | One of the things you often hear about LED lights, is their beam angle is narrower compared to old fashion incandescent lights, and even compared to newer CFLs.
What performs this mean and is also it a problem?
The beam angle is the angle where light is directed in the lamp. So a small angle of 20 degrees will be appropriate for a spot light, focusing light on only one small area. If you want more general lighting, spreading light over the whole room, a larger angle of perhaps 90 degrees will 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 that have been indeed made for focused light inside a narrow area. Today this really is no more true. New technology now ensures that LED lights are available inside a wide variety of beam angles, from narrow spotlights to wider general lighting. Some LEDS can be obtained inside a variety of beam angles from 15, 30, 40, 45, 60, 90, to 120 degrees. What this means is there is a lot of choice on the market, sometimes so much choice that it gets confusing for the buyer. You can no more just grab a lamp in the supermarket shelf. There are decisions to get made!
