I like spotlights because they allow high light plants to be grown next to low light plants and I believe this is the next phase for aquascaping.
But disagree with all the other features. For example I had an arduino controller at one point which allowed me to control sunrise sunset cloud cover and lightning but I ended up ditching it because I realised that my tank was in my living room and was getting all those things through the window anyway. And as for controlling it with my iphone, well, I got into aquascaping to look at fish and plants. Not another screen.
I would have preferred a manual more basic model without the lighting modes and just lenses and swivels that can be adjusted and focused by hand. This is where I think Kessil got it right. I may be wrong but i think it also doesn't have the ability to adjust the width of the spotlight, which is actually more important imo. Unless the quality of the lights is fantastic I think the average hobbyist would still buy a Kessil.
