I see you didn't show the green version in the update pics
I thought you were commenting on the green tint of the "white" picture from before.
Here's some real green for you, bro.
2 questions Vegas ....
How the cleaning is performed around the LEDs -- niches -- ?
How and where the EC allows them to be installed in the configuration -- niches close to the tub area -- you have ?
The niches just get wiped down if they need cleaning. For both of the showers in my house the LEDs are installed in niches, up in the niches. You'd have to really try to wipe the strips themselves.
As far as code, an inspector could turn this stuff down if he really wanted to. Not because it's particularly hazardous, but because every single component doesn't have a UL listing. These are the same components I use in commercial wet location installations in Vegas. A solid install doesn't raise any questions, as there should be nothing but low voltage(12V DC) in the wet area, and class II wiring restrictions are a bit looser than class I. When the class I side is GFI protected(which is about worthless), that's as far as most usually care about.
When I piece these together, I pay attention to IP ratings. This is a basic IP(Ingress Protection) standards chart.
The second digit is most important. An IP 65 is a minimum for the way I did these, even though that exceeds actual conditions. Standard WP strips are usually rated 65(top). Next is a 68 rated strip. Double chip density(BRIGHT), and immersion rated for fountains/aquariums/etc(middle). On the bottom is a nice low capacity WP xfmr I found. That itself is rated as a 67. No need for it in a dry area, but why not.
Making connections in the wet area is only done with solder, and heat shrink. I'll re-seal the conductor end, and seal any ends that have been cut. Everything else is in a dry area. In this case, an access in a utility room, on the back of the wet wall, where I have shut off valves and a recept controlled by the wall switch.
