For the meantime I will start doing the LED lights that I can use for my existing 100g tank and eventually will be used for the 180g.
Here's the list of materials that I have right now.

6x Mean Well Dimmable Drivers PCD-60-700B good for 20 LEDs
65x 3W 14K White LED
65x 3W 450-455 nm Blue LED
6x 3w Red LED
130x 60 deg lense
6x 12x5 heat sink
6x 12V fans
2x Omni dimmers
1x 50ml heat sink compound
I need your thoughts on the following options.
LED configuration per module
1. 10 Blue, 10 White
2. 10 Blue, 9 White, 1 Red (no lense)

Number of modules for a 180g tank
1. 4x 60W modules = 240W less powerful, spread of light is just right for a 72x24
2. 6x 60W modules = 360W more powerful, light falling out of the tank
