Wow 200 watts of pc lights on a 15 gallon is good i think. I only like metal halides cuz they make the skimmering effect otherwise they cost more to setup.
I got the ballast off some guy in the states, it was like 60us for 150w electronic ballast. Not bad. Then I had to diy everything which was hard at first cuz I never did it before. But once I got it completed, it was all worthwhile.
I have another 150W pendent on my 20 gallon too. So thats 300W on a 20 gallon high.
