about 7.6 -ish

38A * .8  (to give us a safe range of max power) = 30.4A usable

flex strips use about 4A

30A/ (4Aper device) = 7.6 device

Thank you Chris. How did you arrive to the flexstrips using 4amps?

[chrisatpsu]

Flexible strips 13ft 50/50 nodes Red +, Blue - , Green Data

• Arrows show direction
• 1 (120 nodes each)
• approx 3.96 33ma each

in the wiki.

you can count on a maxed out string of whatevers to be around 4A@12V
