PAR testing video done here. At first glance, this lights reminds me of the NICREW brightled which only comes in one size and lacks RGB. It is a sleek fixture with metal heat sink construction. Height is not adjustable but could possibly use a DIY to hang it from a ceiling. The Twinstar 90B is compatible with Ultum Nature Systems 90B and 90L. Spectrum is between 7000-7600 as seen in the testing video.
PAR tested using Seneye PAR meter unless otherwise noted in the notes section. Testing process is documented here
