That there will be more luminous flux in some directions and it can increase the illumination of the target surface.

For example:
Night: 0.001-0.02;
Moon light night: 0.02-0.3;
Cloudy indoor: 5-50;
Cloudy outdoor: 50-500;
Sunny indoor: 100-1000;
Under the sunlight in summer afternoon: about 10*6 power;
Reading books for intensity of illumination: 50-60;
Home video standard intensity of illumination: 1400.
