Re: 5mm or M5/6 for Arches??
I did arches with 5mm and with 4' spacing and a 3/4" pipe, all the LEDs ended up pointing the same way so I lined them all up and it looks good to me- very uniform and VERY bright (I need to take a quick video). If you are going to wrap something where the LED end up pointing all different directions, the M5/M6 would be better for light dispersion.
