Building a DIY GU10 light fixture for my fishroom

I want a small light fixture with a bit of a floodlight effect for my fish tanks, and I don't want to pay pet store premiums to get that... so I'm building my lights myself.

I AM NOT RESPONSIBLE FOR YOUR SAFETY. Do not attempt electrical wiring and similar projects unless you know what you are doing. I accept no responsibility for any consequences of trying to recreate this project. Watch/imitate AT YOUR OWN RISK.

I like the GU10 LED lights because they are relatively compact compared to traditional bulbs.
