In this post I give a short video tutorial on how I built the LED fish tank lights for my fish tank. I’m using high-performance Cree XP-G LEDs (XPGWHT-R5) on 23mm star PCBs. Each one outputs 556 lumen at 350mA. I use 6 in this video to give an output of 3,336 lumen at a cost of about 39 Watts from the wall. One interesting thing is that I am using IKEA curtain rail as the aluminium backing for the lights to keep the costs down and because it works very well in my application. The aquarium looks great and it has been working perfectly for several months now.
Here is a link to each of the products used in this video:
