Here is where I hang my head in shame. I have bought dollar Store light bulbs, smacked them around a little and mounted the circuit board on industrial aluminum curtain rails. One thing missing from the post below is I insulated the live section of the modules with a dab of silicone, otherwise you could touch 120V.

It was suppose to be just for a veg tent but then I needed a quick set of lights for some extra plants, and again, after a time I just went with them. They were a buck a bulb for a 14W, they have gone up to $1.50 now though. Other than the heat shrink tubing and bulbs they did not cost me anything. As prices have gone down on leds since I made my first one I may have gone a different way if I started all over today.
