V-ISA Method Lighting: The First Light Source Ever Available

V-ISA stands for Variable Irradiation Solid Angle. The light emitted by V-ISA Light is optimized while maintaining the shape, size, and optical axis of the solid angle of illumination at each point on the target, regardless of the distance from the light source or the target's position. Furthermore, V-ISA Lighting allows you to freely adjust the light attributes of the solid angle within the solid angle of illumination. This completely redefines conventional lighting, allowing you to easily illuminate targets with light never before available to mankind.
