I understand that the WS2811 requires at least 10v otherwise the strips will burn themselves out, however, are they tolerant of more than 12v? I have a powerful 24v power supply and I am powering 600 LED's, and I would like to use it, however, the most I can crank it down with the available pot will only reduce the voltage to 20v. I don't have a 12v power supply strong enough, but I do have a couple of them.
I tested a scrap piece at 20v and they seemed to be perfectly happy, but I fear that it will severely reduce their life. Will WS2811 tolerate 20v fine, or should I use a couple 12v supplies instead?
