12V or 24V for 6.2m strips without power injection?

[ThisPlay]

hi all,

I need to do an installation with multiple strips of 6,2m length. Will this work with 12V strips If I inject at the beginning and at the end of the strip, or do I have to switch to 24V?

Thank you and have a nice christmas this year =)

you can get away with it on 5v strips too if you double end feed properly
