So what do you need? Here are some tips to help you make the right decision to choose the right IRC for your application. First of all, rest assured, LED is a high quality light source. Compared to some of the lights we are used to in the past, metal halides, high pressure sodium, low pressure sodium, LEDs, produce high quality light. And we defend the saying: High quality lumens = less lumens. In other words, you need less light when it is more precise. However, lets talk about numbers. The IRC is a scale between 0 and 100. 100 is daylight, the norm of sunlight. Artificial light always tries to reproduce the quality of the sunlight. IRC affects how colors are represented in light. More specifically, it really affects the red color. Looking at a bowl of CRI 70 gum balls and the same bowl un...
