I'm using a couple of Robin 600 Led units.I'm running them in Mode 2. I've noticed that the zoom parameter has minimum and maximum values of 15 and 50. This is not a problem as I can get the focus I require at both ends of the scale, but I am interested to know why, particularly as I was using them with a Jester TLextra last week and had full control between 0 and 255 on that desk.
