I guess you are right. It looked to me like at 6" only 60% of the tank was at the right PAR (12 minute mark in the Gen2 review) and it was mostly in the center. At 12" it was only about 43%. I thought the reefbrites they reviewed actually did better (I'll have to rereview). I still feel it is an expensive option. I don't really view less options as a perk. I look at new cars the same way. It doesn't matter if I use the option or not... I still compare one car to another based on what it offers. Nice tank by the way! Envious of the number of fish you have.You may want to rewatch the first 3 minutes of the video, it has a PAR well within SPS range over the entire tested surface. Philips just didn't design it around an 'American' colortemperature but around a 'European' colortemperature. So when you deviate from that you also lose performance, certainly when compared to a light designed around that 'American' colortemperature. And the two dial system is saving you money, as it prevents you from being ably to kill your corals by creating the wrong type of light as human eyes are bad at judging spectrum. And it certainly grows SPS, this tank used to run on gen1 and now on gen2 https://www.reef2reef.com/threads/tank-w-vreeswijk.232851/post-7974357
