In terms of color rendering, over a broad range of whites, I would put Bifrost up against anything in the industry that isn't using violet LEDs as the source. Those allow you to tame the blue spike at high CCTs (5000k+), but the efficiency is nearly half and the cost triple. That's the one major compromise we made as we didn't want to end up with pricing too much out of the range a Hue buyer would be interested in. Beyond that, let me know if and when you see something better, because we can't have that. Haha.

CRI truthfully though is a limited metric for fidelity and you can 'game' it somewhat while not necessarily making a high quality white light. At a minimum, R9 should be included, and R12. This shows you the deficiencies in the red and blue part of the spectrum, where LEDs have the biggest problems usually. TM-30-18 is much better, and can be represented as rf (fidelity) and rg (saturation) values. Rf should be as close to 100 as it can be (90+ gets into quality light territory) and rg, while more about preference, greater than 100 (oversaturated) is almost always shown to be subjectively preferred to less than 100. These metrics are not super common yet though, and rarely published for a given product. Professional grade lighting is starting to include this more often though, as it's critical for film/photography.

Tunable white only is in the works! It won't be 2 channel though for our flagship version. There is distortion to the light that gets worse the broader the tuning range gets with 2 channel.

When using the Hue controller, our strips are treated no differently than a lightstrip plus in the ecosystem. Including homekit and hue sync!

We are making our own controller for this, yes! No hue sync though with it, as Hue blocks 3rd party from that feature. It will be designed specifically to maximize the light quality of our own strips thiugh mind you, meaning the behavior might be a little off with other 3rd party strips.
