I had already purchased 2 Arctic-t247 LED lights for my SPS heavy rimless 93 cube build, but only recently plugged them in. unfortunately, the fan noise is more than I would like in my living room. The Razr 160w has been suggested to me, but a 30x30x24 tank would likely need 2 of them. That being the case, it might be less expensive for me to purchase 2 Kessil Tuna Blue lights or 2 Radion G3 pro light. Both seem to offer good mounting options and perform well enough for SPS. However, the real question is about noise! Can anyone compare the two or make any recommendations please? A silent unit would be best, but I'm not sure how realistic that is.
