All these issues you listed are false and shows you haven't done any homework. Whenever you're corrected, you ignore it and keep spreading these false points.
1) How close your light needs to be to the canopy has completely to do with how the lamp is designed. Some high density arrays need to be kept extremely far away from the canopy. the cxb3950 designs are meant to be kept far from the canopy. I design my lamps using 2530 specifically so i can be closer to the canopy. It's my
choice as a designer. Lamps built using vero 29 or cxb3950 are "high profile designs" like you want. Simply pack on more density... duh.... What's dumb is that a low profile design will actually work in a high profile setup, but not the other way around. You're boasting a DISADVANTAGE of HPS.
2) Nobody here is boasting purple lamps. We're boasting white ones. Repeating "purple" "purple" makes you look dumb as shit. No purple!
If this looks purple to you.... I dunno what to say. You need your eyes checked out. It sounds to me like you're just willfully ignorant.

3) Go to the right store...
What do "we" know you're asking? Collectively, we know a lot more than
you know as an ignorant individual with his head up his ass.. Work on your reading comprehension.
