Look at it from Ecotech's side. Why would they want to be like any of the three lights you guys have stated? They are on the top of the mountain when it comes to Aquarium LED Lights. There is no reason for them to look to the bottom of the mountain for inspiration when every manufacturer is looking up wishing they were them! Yes, those three companies are at the bottom looking for scraps!
Although Phillips has potential and a massive bankroll behind them, so far, they have not been willing to open that bankroll to fund a truly competitive solution in this fringe market. They have instead offered a aesthetically unpleasing commercial warehouse light fixture that they were already producing. Sad really as they could have chosen a more appealing look such as this...

I can actually see hanging one of these above my tank. Not to mention that each of these fixtures weigh 1/3 of the weight of the current fixture.
As for GHL, I truly believe it is one of if not the best engineered LED light . But I cannot ignore the fact that in 2018, they still need a PC to do the initial program before they can be controlled by other devices. I'm a Mac user and once I found out, this fell off my list of contenders. I guess that's why we don't consider Germany as a technological hub for software and computer innovation.
I'm not a fan of Orphek simply because of the materials. Just not sleek enough for me. Not a fan of the fit and finish, Anyone can put a light between two pieces of acrylic and some aluminum mesh that fits in a grove around it. I am shocked none of the other black box manufactures have not done this yet. Before you get mad, there have been multiple people who have commented that the Orphek inside looked just like their previous black box leds when they opened them up.
I'm not saying that the above mentioned lights are not great in their own way. I am saying that they are missing something that appeals to the masses. IMO, the Ecotech Radion, AI Hydra, and Kessill lights have the right combination of features that is keeping the others on the bottom.
