Greetings,,,
I personally use the pipe, but if you wish to try other things, there must be thousands of ways to do enclosures, at all price ranges.
You could walk through the dollar stores, electrical areas in the big box stores, or buy from plastic houses online.
I'd stay away from anything that could conduct electricity. No need pushing your luck with shorts.
But in the end, the lights get all the cool looks at night.
