I got 2 x 400W'ers on there now, just the two on the right. Bulbs are 14K's. I'm absolutely amazed at how much better lit the tank is now (photo doesnt really show it that well), but am still very impressed by how well T5's can do. Take your choice on lighting (be aware of the halide combinations though and that the middle 150W'er in the first p
Here's the tank with 3 x 150W'ers (14K, 10K, 14K) and 4 x T5's (2 whites and 2 blues)
Here's the tank with 1 x 150W (left, 14K) and 2 x 400W'ers (middle/right, both 14K) No T5's (I have 2 x white T5's still to hook up, one front, one back. Cant afford 3rd 400W'er til next month)
Colour wise, I think I like a middle combination of the two. Intensity wise, even though the pic with T5's looks intense, there are large shaded areas that the 400W with lumen arc reflector covers with ease (see right side of glass where stream is)
