Nice light. Really like it. Do you think 12 bulbs will be enough? Roger has 8 over a 4' tank so I was thinking I needed 16 on mine to cover. Since I know very little about T5s I am just asking. Also didnt you have LEDs on your 120? I have LEDs on everything but it seems almost every really really nice tank I see has MH or T5s. Thats why i am jumping ship on my new build. I really hate to because I know there are some super nice systems with LEDs but they are so dam hard to get dialed in that T5s just make it simple. I like simple!!!!
