This is a question I find myself pondering a lot recently guys, nice one for putting up Planted Bows.
I have the same reservations about the Chihiros RGB but had wondered about getting the 60 cm and turning the stand in reverse? Can anyone think of any reason not to? I know there would be a bit of overspill but because I'm not limited by stand even pondered the overspill for some attempt at small wabi/emmersed too, I'm nowhere near buying yet and the longer I put off the more likelihood there'll be something even more shiny to tempt me.
I'm not even a great star trek fan but there's something about all the Kessil range that makes me think of the old school enterprise which makes me want them for that but far too rich for my budget at the moment. I got 2 10w RGB aquaone units and the difference in rendition between the two is noticeable and I believe they're meant to be the same kind. What I mean is there's something about the reds. Also I'm trying a 15w 6500k cob fleabay hill-billy ikea spot at the moment but I'm not convinced by it. Its bright to the eye - to the point I reckon it was contributing to my sore head since it's the room I'm most in, but everything looks pretty healthily weird.
Good luck with your quest will be following for sure.
All the best
