on the LED replacement portion: A blown LED might not cause all the rest of the other LEDs to fail. It very much depends on how the LED circuitry is done. A well thought design would have avoided that. The new MaxSpect G2 allows you to swop out the LED (think they will be individually connected) without too much hassle and it will not void the warranty. You can simply purchase another few LEDs as standby and use them to replace faulty ones.
LEDs should still last much longer than a T5 tube or MH bulb for the same effectiveness period. Think Sherman, Rocky, Jameshong has been using them for quite some time already. This is one of the reasons for moving onto LED. The others are less heat transferred to the tank and hence less power consumption on the chiller.
AquaLumen : Yes the dial and the colour tone adjustment is unique, abeit at a much higher price.
