https://www.youtube.com/watch?v=tCSbukB3Ieg makes a lot of interesting points about these Chinese "black box" lights, to me the most worry-some is their use of super cheap non-UL listed power supplies which may pose a fire hazard, backed up by the fact that they don't seem to be sold by any retailer that one would have a realistic chance of suing if they burn something down
First question: Does anyone know a UL listed intermediate between these super cheap lights and the $650 level lights like the radion XR30w? I am finally thinking of converting over my 31" deep 300 gallon which is mainly lit by 1200W MH pendants and
a couple of T5s and LED strips, I would want a lot of light
