I have two RSM 130 tanks converted to LEDS. One has the RapidLED conversion and the other is Steve's LEDS. I am getting great coral growth with both systems, but my preference leans heavily toward the Steve's systems. The RapidLED system has three set programs if you want the sunrise/sunset and you lose the stock moonlights. the Steve's system has a programmable Typhoon controller, keeps the stock moonlights, and has dimmer knobs which can dial in your color preference. I am extremely pleased with the upgrades and would not hesitate to do it again.
