To whom it may concern,

It is really gratitute if someone else can share info with all viewers in forum. There are three crucial inputs that can enable the uniformity no less than 0.4 or 40%. i). Reflection factor on roof or ceiling, wall and ground. ii). The luminaire can luminate the object in the farthest of the calculation surface in compliance to the uniformity. iii). The height of luminaire.
