First of, I would like to commend you on your amazing effort to see this to the end even through some very hard design challenges. This is truly inspiring in so many ways. I have been following this thread for about 18 months now, and this is the first time that I feel that I have something worth while to say about the design. I should also point out that I won't be one of the lucky few that can afford or justify purchasing one of these awesome lights, so my opinion shouldn't be considered with the same weight as BVH's or any of the other potential buyers.
With that said, I would like to say that I am a bit torn between the more clean layout of the display and the more graphic one. As they both stand right now, I would probably choose the less graphic one since its color-scheme really complements the texture of the carbon fiber and the other graphics on the light. My main issue with the more graphic of the two is that it has (in my opinion) too many different shades and nuances of color. I think that the culprit here is the fact that the bar graphs are solid color which kind of mismatches the more shaded icons, and there also seems to be differences in hue which kind of makes it look a bit too much like a candy store (absolutely no offense meant, it is just the best way that I can describe it). If these bar graphs were a bit more matched to the overall color scheme, I think that I would start preferring the graphic display since the over all layout of the thing is very much appealing to me aesthetically.
I also think that it might be a good idea to post the pictures of the displays side by side with the graphics on the side of the NS to get a better view of how the lights color scheme would play out in its entirety.
Another thing that hit me yesterday was a detail about the focus slider. If I understand things correctly the light will start focusing as soon as you start moving the slider up and down, as well as focuses directly to the point you set it to by pressing anywhere on the length of the slider. Would it be possible to program it in such a way that the focusing doesn't start until you lift your thumb of the slider which would allow you to set your desired focus by looking at the numbers displayed on the slider and then have it go to that focus directly. And if real time tracking of the thumbs movement is desired, a simple double click on the slider could be used to go into real time tracking. This could also be applied the other way around. I just thought that it could be a neat little detail for the user interface.
Once again. Thank you for letting us follow your journey to the perfect light.
