Semi-Direct Light Scheme

With the help of semi-direct reflectors, 60-90% of lumen emits from the light source. It is mostly used in rooms with high ceilings and where the uniform distribution of light is required. Mostly used in working place.

Indirect Light Scheme

This is the reverted process of the direct light scheme. In this, the light is thrown upward to the ceiling to get 90% diffused reflection. Mostly used for decoration purposes to create an optical illusion and in cinemas, hotels, etc.

Semi-indirect Light scheme

Here 60-90% of light is thrown upward with the help of defused reflector to get this light scheme. The remaining lights reach the working surface without getting absorbed. Mostly used for decoration purposes

Diffused Light Scheme

Here most of the light is diffused around the subjects. It is done by using lighting fixtures. It is used where uniform illumination is required.

Tips For Arranging Light Bulbs

Light bulb arrangement is important hence dispersed use of light bulbs can make everything look ugly and indisciplined. Here is how you can arrange them.
