Lifx z max strips (10? or 4?)

Hello Experts -

I am new to Lifx and trying to figure out how much lifx z strips to buy.

i saw this site describing specs - https://www.lifx.com/pages/lifx-z-starter-kit-specifications
it shows 30w max per controller, and 2 strips (2m) takes 17w.

i.e. 1 controller handles 4 strips comfortably.

then i googled to find max number of strips per controller -
https://support.lifx.com/hc/en-us/articles/217234786-LIFX-Z-Setup

it describes maximum of 10m per controller.

does this mean, if i actually use 10m of strips for 1 controller, it will be extremely dim??

i notice this question asked before… but didnt get an answer…

anyone has 10m of strip care to advise?

The last paragraph of this support article supports what you suggest - 10 (or 5+) strips will be dimmer:
