Listen to him in the interview, he says light is still important, he doesn't say light level talking in future tense, light is likely changing so its value is different as it is being separated from what level you currently are. Old gear might not change but the new gear is likely different hence white or green stuff can be better than the old purples. Again I can only go on what I have heard from Deej in his interview. Below is the one im talking about, you want to look at around the 4 minute mark. https://www.youtube.com/watch?v=9cNIu0fMtMg
