Help Me I am Tried of Reading

[BaliReefBox]

OK I need to upgrade my lights sooner then later. I have a 90x45x45cm tank currently running 2 Maxspect Jump MJ-L165 blues (65w). I want to get reefi uno 2 pros but cant until my next trip to the states..shipping and taxes will kill me.
Now here it is the question for those who have had them.

Two Radion xr15 blue g5 at $600 AUD or xr15 blue g6 at $~800oz...

Is the G5 going to put out enough PAR, I have read the g5 are noisy and put out hot spots... I am sooooo confused and as mentioned sick of research....please push me in the right direction

I'd stick with the G5 - they put out more power but less spread than the G6. My XR30s are a lot louder than my XR15s, so unless you running everything @100% they should be fairly quiet.
