We got the light itself from the local dealer and that was ok. Not the speediest, but gave us a chance to discuss aspects of various lights in order to make a decision. Our intent was to get the best equipment possible, and the vertex gave us the most flexibility, and I really liked the idea that it was modular. Which was proven to be a really good thing (modular design) cause within the first two weeks, the control end cap took a small dip and although it still worked, we couldn't adjust any light levels or talk to the computer. On a 2800.00 light (Canadian), the end cap with the control board cost us 125.00 to replace. That was a lot better than we expected and also easy to change ourselves so avoided not having light if we had had to send the whole fixture in for repair somewhere.
The computer light interface program can be a bit weird at times. I have a habit of loosing points, and I don't know why, or how. The only way to check and make sure I haven't done something stupid is to close the program and then re open to check and see what the settings were saved as. I save settings, upload program to light, do everything right, (I think), but somehow, I generally manage to loose a point. It's working now, and I have figured out how fix it, just a little weird.
I 100% still recommend the vertex light over anything else! and we are going to get a little 12" one for over the nano tank build we are doing this winter.
