LED light angle is divided into effective angle and the actual light angle. The luminous intensity value is half the direction of the axial intensity and the direction of the light-emitting axial (normal) is the effective angle. Half of the half angle of the angle (or half power angle) is the actual light angle. In the axial strength of half the angle because the light is too weak in practical applications do not count the effective angle. (The picture below shows the side view of the piranhas particles, the angle between the solid line and the dashed line is not included in the effective angle)
Eyeball: This trim is a versatile lamp for art lighting. It can be swiveled left to right as well as aimed up from vertical on a wall. It does protrude below the ceiling line, and so would be more visible.
LED bulbs have grown in popularity over the past few years and it's not hard to see why. Not only do they last longer, but they can save you a ton in energy bills when compared to the less efficient incandescent. However, before you pop into the store to purchase new LEDs to replace your current lights, here are some interesting facts to consider.
