Twinkling Led Christmas Lights | One of the things it’s easy to read about LED bulbs, is that their beam angle is narrower than the old fashion incandescent bulbs, and even than the newer CFLs.
What performs this mean which is it a difficulty?
The beam angle may be the angle where light is directed from the light bulb. So a little angle of 20 degrees can be suitable for an area light, focusing light on just one small area. If you want more general lighting, spreading light over a whole room, a more substantial angle of perhaps 90 degrees can be preferred. In most domestic lighting situations beam angles of 30-45 degrees are sufficient to light a space comfortably.

The idea that LEDs have narrow beam angles stems from the older technology LEDs which were indeed suitable for focused light in a very narrow area. Today this can be don’t true. New technology now signifies that LED bulbs are available in a very wide range of beam angles, from narrow spotlights to wider general lighting. Some LEDS are available in a very range of beam angles from 15, 30, 40, 45, 60, 90, to 120 degrees. What this means is that there is a great deal of choice in the marketplace, sometimes so much choice it gets confusing for the buyer. You can don’t just grab a light bulb from the supermarket shelf. There are decisions being made!
