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)
There are many kits available in your local home improvement and lighting stores. These kits contain all main parts and accessories that are needed to install the track lighting. If the place where you want to install the lighting does not have a light box connection on the ceiling, it is recommended to get the whole job done with the help of a reputed electrician, as he can set up the light box, run the wires to it, and then install the track lighting. If it already has an electric box, you can install the track lighting yourself. But make sure you refer to the installation and safety instructions that come along with the lighting kit. Kits are available from $50 to even $500, depending on the design and specifications you want.
A desk lamp is not going to take up so much space. They do well on the side of a desk or at the end of a shelf. Some models have features that allow the lamp to be clamped to a surface or hung, depending on how they are to be used.
