Because I've directly compared them against xho's and OR2's. Xho's have great blending because they're only 450/470 diodes, so there's not a lot to blend. The Quanta's have 2 diodes per lens and the blending is night and day compared to Orphek. In order to mitigate the separation of the Orphek's, you have to mount them so high, they become useless or less efficient. I don't see any separation with the Quanta's, but I do see a nice subtle shimmer and not the disco ball you get with Orphek bars. You actually get more light with the Quanta's than the Orphek's at virtually the same price, plus you get a better spectrum. If I were to choose LED bars as my main light source, I would pick Quanta's over everything else on the market right now. Now with The Helix and the upcoming Atlas fixture, I think a lot of people may seriously look at a much more affordable and better option than most major manufacturers offer currently. I think people like Danial (Reefi) and Luca (Quanta) are pushing LEDs into the future and will push others to do the same. LEDs for the most part have been stagnant in a lot of ways for a long time, but this is my own personal opinion. I love seeing fixtures like ATI's Straton, but I don't think they are worth that much money and are cost prohibitive for most.
