So I ordered the light. I figure for $60 if it's no good, I won't be out much and my husband can use it for something lol. A few things I noticed is 1- it only has one power cord, lights are either all on, or all off. 2- no dimmer knob. Reviews say it's lighting power is about equal to a radion on at 100%.... is this a bad thing? Any ideas on how I can dim the light a little to let the tank adjust to the higher light? Or will it be a non issue and I should just plug it in and let it run?
