Ohh built/custom housed LEDs are a no from me.

A good LED bulb can last a long time, but only the bulbs are interchangable. And often the chips overheat and fail even though in theory these lights can last 20+ years.

Now when there's an issue you have to throw out the whole housing, which makes you have to buy a whole new set of lights.

There was a an angry nerd guy who had like a 30 minute video on just this, but I have no idea what his name was. He also has a see through dish washer video if that helps you find him.
