My first CF lighting had the square pin bulbs. I replaced the 50/50 with a 8800k and then replaced that with a 6700K witch I think grows plants better. When I redid all the lighting on all my other tanks with CF. I when with the straight pin form AH. The bulbs I used are from Atlanta bulb co. 9325K for around $17. I can't really say witch one of the lights you are looking at us best but I would prefer lights that sit on the top. Light penetration in large tanks is more important then w/gal.
