Not sure What you're asking.
What size, how old are your plants?
18 inches for flowering it sez.
I'd use the Manufacturers recommended hanging heights.

It reminds me of the Amare lights.

The reason why some run them closer is probably due to fact that they are Not using lens/reflectors.
You can get the cobs much closer to plants run bare, without lenses.
Your plants are looking good.
I've never done Autos before. How many hours a day do you run the lights at?
I believe with Autos you don't need to give them as intense light as regular seeds as light is on for longer period.

So I actually had that lux app already on my phone which I know means nothing but, I tested at 18" and I was only pulling 22k lux. I went down to 15" and it went to 37k lux. Here is the PAR chart for my light at 18" in a 2 x 3, I have a 2 x 2. Just wondering if the light is too low. I am open to all opinions here. Just don't want to burn my girls. Specs on my light:

Max Power: 205 watts

LEDs: (high potency Ultra Violet & Infrared Equipped)
