yeah they are around 400. With the 150 and a 160 you will have a lot more light. If you hang them close together the different colors should merge, at least to your eye. Can always add more later. I started with the 2 160s on a 6 foot tank then added first one 360, so I had one 360 on one side and 2 160s on the other. I later added the second 360 and configured them with one of each on each side. I have that same configuration now on the 5' tank. I will add another 360 maybe this summer then maybe a fourth.
