Blue White Icicle Led Christmas Lights | One of the things you often hear about LED bulbs, is always that their beam angle is narrower compared to the old fashion incandescent bulbs, and even compared to the newer CFLs.
What creates this change mean and it is it a difficulty?
The beam angle is the angle of which light is directed from the light bulb. So a tiny angle of 20 degrees could be right for a spot light, focusing light on one small area. If you want more general lighting, spreading light over the whole room, a greater angle of perhaps 90 degrees could 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 from the older technology LEDs which are indeed created for focused light in a narrow area. Today this really is no longer true. New technology now implies that LED bulbs are available in a wide selection of beam angles, from narrow spotlights to wider general lighting. Some LEDS can be purchased in a selection of beam angles from 15, 30, 40, 45, 60, 90, to 120 degrees. What this means is always that there is a great deal of choice available on the market, sometimes so much choice which it gets confusing for the buyer. You can no longer just grab a light bulb from the supermarket shelf. There are decisions to get made!
