I've got an Aqua One AR380. Its a 10Gal aquarium which is 18 inches tall. Currently lit by one fluorescent 11w of some sort. This isn't enough light to grow the plants I want.
So I'm going LED. I've got some electronics understanding, so I don't see wiring to be that big an issue.
I'm having some problems selecting parts though.
So far, I've got 8 x Cree XR-E Q5 LEDs for lighting.
I need help with:
1. LED Drivers (What do I use? I want to drive the Q5s at at least 700mA)
2. Power supply from wall -> LED Drivers?
700mA * 8 = 5.6A
(Driving Amps * Amount of LEDs = total current).
5.6A * 12V = 67.2W
(Driving Amps * Driving Input Voltage = Power supply total wattage needed.)
Does this mean I can get an old 200w computer power supply and rig up the LED drivers to the 12V rail on the power supply?
Basically I need to make sure my maths is correct and I'm on the right track. Secondly, Where can I source the LED Drivers from? I've already got a supplier for the LEDs (dealextreme.com/details.dx/sku.2394).
Now I need a place to get 10 of the LED drivers (8 for production, 2 for testing in case I blow some or something
If someone knows a place that sell these online, It'd be great if the store ship overseas as I'm in New Zealand.
