1. Direct Lighting System: It emits light in the range of 90 to 100% directly on the surface of plane. Generally used, for typical illumination of rooms and public spaces. 
2. Semi-direct: In this case, 60 to 90% lighting goes in downward direction. At the same time near about 40 to 10% is directed upwards. It provides generally a good illumination with brightness in moderate range.
3. Indirect: In this case, 90 to 100% of the light is directed upwards and in this case, ceiling is used as a reflector and helps the light to bounce. This type of setting often results in low contrast environment and cast many shadows (Smith, 2018). 
4. Semi-direct: In this case, 60 to 90% of the light is directed upwards and about 40 to 10 percent downwards. Thus it helps the ceiling to get more prominence. 
5. General diffuse: It provides more or less equal proportion of light in both directs upwards and downwards. Thus, this setting illuminates both the lower and upper horizontal planes. In a typical setting, this type of luminaire consists of a translucent fixture that is suspended from a certain height. 
2.  The progression of fire:
When some sort of combustible fuel chemically reacts with oxygen, the process results in ignition of fire. For the fire to ignite or progress,
