Warm White Twinkling Led Icicle Lights | One of the things you often learn about LED bulbs, is that their beam angle is narrower than the old fashion incandescent bulbs, or even than the newer CFLs.
What does this mean and it is it a problem?
The beam angle may be the angle of which light is directed from the bulb. So a small angle of 20 degrees would be appropriate for a spot light, focusing light on only one small area. If you want more general lighting, spreading light more than a whole room, a larger 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 concept that LEDs have narrow beam angles stems from the older technology LEDs which are indeed suitable for focused light in a narrow area. Today that is no longer true. New technology now ensures that LED bulbs are available in a wide array of beam angles, from narrow spotlights to wider general lighting. Some LEDS can be bought in a array of beam angles from 15, 30, 40, 45, 60, 90, to 120 degrees. What this means is that there is a lot of choice in the marketplace, sometimes so much choice it gets confusing to the buyer. You can no longer just grab a bulb from the supermarket shelf. There are decisions being made!
