Hi Keen to get my tank going but needed to get the lighting sorted out first. There is more detail regarding the planned setup in my introduction post. Tank is 50cm (L)x 40cm(W) x 36cm (H). I got quite stuck into the build so didn't take too many pics. Used ply wood, 57mm hole saw, downlight holders, wires and connectors. I chose to wire in parallel, made more sense. Did not wire in the earth connections, should I have? Wiring almost complete. Need to connect to the switch still. The corner lights are 5w day lights and the middle row has one blue and one red, both 1.5W. Might change this if I can get a stronger red light. Sorry about the pic, taken with my phone and not sure what to adjust to help decrease the glare. The wood is not varnished, just oiled with liquid paraffin. Will seal around the downlight fixtures. What next? I need to make a frame to go behind the tank to hand the lights from. Thinking about 15cm above the tank, trying to prevent condensation. Your guys thoughts? Improvements? Doug.
