Trying Cooper HALO SMX Edgeless LED Edge Lights, Without Buying Any

I am informed by dates of Home Depot customer reviews that SMX  families of Cooper HALO Edgeless LED Edge Lights have been available online at homedepot.com, since December 2024. At this writing there 3,939 Home Depot customer reviews, averaging 4.6 stars. 

Tunable White: Field-SeleCCTable color temperatures (2700K, 3000K, 3500K, 4000K, and 5000K) and Dim-to-Warm options that transition from 3000K to 1800K, perfectly mimicking incandescent lighting.

The only useful color selection is in close proximity to 3000°K. 5000°K is absolutely useless. 1800°K? How could that be useful?

I am interested only in circular shapes. 

Dimensioned side views are presented, including need-to-know dimensions, for four of the five sizes offered.

There is rotate-o-mate engagement with a mounting plate upon a junction box. Be wary that very large lights centrally captured, may not seat firmly on the ceiling plane.

The HALO SMX families brightness choices are very much not related to the illumination potential at diameters greater than 5 inches. Luminance of 0.05 lumens per square millimeter, that of the Moon, is borderline comfortable to gaze upon, not glaring. It would make sense to offer that luminance for all families, and to let lesser illuminance be achieved always by dimmer control. There can not be a demand for light power control by climbing upon ladders to reposition luminaire control switches. Dimmers do the job, and that is that.

Lumens output at fixed diode power, in proportion to diode tape circumference if 633 lumens at SMX 4:

Perhaps Cooper/ HALO might innovate usefully against edge light limitations.  Get more lumens out of LED edge lights by adding luminaire depth, with multiple diffuser lenses and diode strips. Just maintain a luminance limit of 0.05 Lm/mm2. Or, teach that bigger luminaires don’t add up nicely in illuminating a room; then prefer better light distribution with many smaller lights.
