its tricky to compare because ours are designed to be integrated into a space and create the appearance of window with a big focus on high CCTs (2200k-40,000k) which relocates the color and spectrum of a blue sky using up to 180W. This lamp seems to be focused on lower CCTs (1800k-5000k) at high powers (750w is a lot of heat to dissipate). Both have similar Rf and CRI but we maintain great Rg and CRI across the whole range.

The one you linked is a stand alone lamp and they seem to focus on red light which I don’t quite understand. Red light (or very low CCTs) is used for skin therapy but typically requires direct exposure to the skin because irradiance levels need to be super high for that - from my understanding you wouldn’t have any benefit from a red lamp even at 750w. But blue light does can have lots of health benefits at low levels (search for ipRGCs).
