Ive just received a pair of these lights and they do feel to be a huge upgrade over the ViparSpectra V165 I had running on my tank. Early days yet but I'm liking it so far. Colours are great, but running with limits to let my corals acclimate.
I did have an issue with the arm mount, the top of the arm wasnt tapped (needed a 6mmx1mm thread), so I had to tap a thread it in to get the arm assembled correctly. I assume this is a quality control problem rather than by design, I nearly stripped the M6 bolt trying to get it in there before tapping.
I'm also very keen to see the upgraded lights with wifi. Tuya based is great. I've got HomeAssistant setup at home and it would be great to have that next level of control for the lights. Hopefully there will be a affordable upgrade path for the current generation hardware.
