example led strip 12v 2818 chip 60 leds/m Ray's page says 14.4w /m on an 8.8 metre length I calculate 10.56 amps Davids led calc page doesn't list 2818 or 60 leds/m so I used 2811 12v 30 leds/m but put in 17.6 m for the length it comes out at 9.76 amps yet the current version of xlights is telling me 31.32 amps , am I not calculating this right?
