So some people wanted me to do a build thread of my dual LED cannons so here it is. It will be going over a 29g tank.
Typhon controller with with LDD board from O2Surplus
Each color will be fully independently controlled so I can dial down the desired spectrum. Light will be on a 12-hour cycle but with dawn and dusk ramp ups of 3 hours each as of right now.
Luxeon ES from stevesleds (No optics)
12 - Cool White 6400K (6 per cannon)
2 - Deep Red 660nm (1 per cannon)
2 - Cool Blue 470nm (1 per cannon)
2 - Hyper Violet 420nm (1 per cannon)
Each color string will be wired in series.
3 - LDD-1000H (whites, blues, and greens)
1 - LDD-700H (reds)
These drivers are tiny and super cheap ($5/ea). You can load from 2-52v on them and they use a 5v PWM signal. Another great thing about these is that you can can dim to 0%. They will be wired in parallel to the PSU.
350w 48V 7.4a power supply (absolute overkill but was cheap)
24w 12V 5a power supply for Typhon and LED fans
Going with these drivers and power supply will allow me to add 2 more cannons to the system very easily without much modification.
2 - Intel Ivy Bridge heatsink/fans (these can cool 70w of LEDs easily)
3/4" aluminum flat bar from home depot for mounting plate for the LED
DIY acrylic pendants for housing the cannons and misc hanging hardware
Cat5 cable for running the pendants to the Typhon (4 strands per string)
I made the pendant housing tonight with scrap acrylic I got at the at the store. Bonded together with IPS Weld-On 4.
This is the housing - 4x4x4"
This is the heatsink with the flat bars. The flat bars will go on the heatsink with Arctic Silver Alumina thermal adhesive. They are cut in 3" lengths for 3 rows of 3 LEDs.

The LEDs from steve should be here early next week as well as the meanwell LDDs.
