This instructable will show you how to safely add LED lighting to a fishtank/vivarium. I’ve tried previous versions of night / moon lighting in the tank, but none were up to the task:
Moonlight v1 – waterproofed high power LED’s attached to the side of the tank – these gave pretty good lighting but there were too many pools of light in the tank, and also the number of wires was pretty unsightly.
Moonlight v2 – Cold cathode lighting (from a PC mod kit) , however as Ive got a large tank (180ltr) and I needed to extend the wires from the cathode tubes to the inverter – however when I did this I found that they no longer worked anywhere near as well (it seems this is a known issue with cathode lights).
So….back to Maplin and moonlights v3 is here!
