Design Classics Lighting | One of the things you often read about LED lights, is that their beam angle is narrower as opposed to old fashion incandescent lights, as well as as opposed to newer CFLs.
What does this mean which is it a problem?
The beam angle may be the angle at which light is directed from your lamp. So a small angle of 20 degrees would be right for a place light, focusing light on one small area. If you want more general lighting, spreading light more than a whole room, a bigger angle of perhaps 90 degrees would be preferred. In most domestic lighting situations beam angles of 30-45 degrees are sufficient to light a room comfortably.

The indisputable fact that LEDs have narrow beam angles stems from your older technology LEDs which were indeed suitable for focused light in a narrow area. Today that is no longer true. New technology now signifies that LED lights are available in a wide range of beam angles, from narrow spotlights to wider general lighting. Some LEDS can be purchased in a range 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 on the market, sometimes so much choice that it gets confusing for the buyer. You can no longer just grab a lamp from your supermarket shelf. There are decisions to become made!
