The Radions were no doubt given to him, but he did conduct a good comparison of the effect on his corals response between his MHs and the new LEDs in the same tank for four months. I would take it with a grain of salt and see how things work out for the long-term. If he stays the course, he will still be using these a year from now.
Don't be a playa hata...I have seen a lot of his videos and think that he does his best to recommend good products and does identify things that should be considered for improvement. He does try to cash in from time to time on reeftank user guides, etc..
...This has been your Thursday evening quick tip...until next time...enjoy your weekend...enjoy your tank...and know your tank personality
