diy aquaponics system pdf
It has been a while for me wanted to try LED light but it always been turn off due to the price as well as the fact that not all LED light set in the market can grow plant. Most of them just bright enough for us to see but not for plant to grow. It may not designed for planted tank. The one that design for planted tank cost very-very expensive. So I decided to DIY my self.
My target is to replace my 2x55W PL light set with LED. I choose to use CREE 3W led because I read from forum and some people said that those small LED does not have enough PAR. This project total cost is about S$30 for each row, my plan to make 2 rows for better coverage.
By the way, I found this light calculator to calculate PAR for different type of light. http://www.defblog.se/LightCalculator/
Material:
1. Two 62x5cm aluminum plate, used as a heat sink
2. CREE XR-E Q5 LED x6
spec:
- 3.7V typical driving voltage
- Manufacturer Rated 228 Lumens at 1000mA input current:
350mA: 107~114lm
700mA: 171.2~182.4lm
1000mA: 214 ~ 228lm
3. Two 900mA 10W Constant Curent Source LED Driver
spec:
- 10 watt high power LED driver
- Input voltage: AC 85~265V
- Output voltage: DC 9~11V
- Output current: 900mA
4. Miscelaneous items: thermal paste, screw and bolt, cable and small container
Drill some holes on the Aluminum plate to mount the LED 
Drill some holes also on both edge. This is more for safety, to prevent the module from droping into the fish tank
Drill holes for LED mounting 
LED is screwed to the aluminium plate
Finished module
