[QUOTE="Mr_Pot, post: 2092744, member: 216415"] With a screen you are looking at the light it emits from red, green and blue pixels and the balance will have a colour temperature. If you are looking at something [U]under[/U] a light then you need a continuous spectrum for all the colours of the object to be correctly rendered which is where CRI comes in. You are quite right in that respect incandescent bulbs are like daylight as they both have a continuous spectrum generated by heat. LEDs generate light at specific frequencies ( originally only red) but the technology is getting much better and closer to natural light. [/QUOTE]
