Most LED strip enclosures (e.g. for mounting under stair risers or cabinets) direct the light in the opposite direction from the mounting surface. But I'm looking to direct light towards the surface where the enclosure is mounted. For vertical surfaces, this is called a "wall washer" (e.g. https://www.beeslighting.com/E41344-BZ). But what I want is a "floor washer" that I can mount under deck railings. It's gotta be waterproof and very sturdy/kick-resistant. Does such a thing exist? If so, what is it called so I can find them on Google?
I'm sure I'm not the first person to try to do downward-facing LED strips on a wood deck. Any ideas? If you've used something like this, did they work well? Any tips or things to watch out for?
Here's more details:
We're almost done with construction of our new deck made of ipe (it's a warm reddish wood) with wood railings over stainless steel posts and cables. The finished product will look kinda like the picture below, although our posts will be rectangular instead of circular.
The last big design decision we have to make is that we'd like to add perimeter accent lighting under the railings. At first our architect recommended to mount LED strips under the railings, but I didn't like the way they illuminated the steel cables instead of the wood, like you can see in this picture:
Instead, I'd like to see if there's some lighting solution that throws light down onto the wood. I originally proposed a second railing near the floor, and then mounting the lighting underneath that lower railing. But the extra stainless steel material and labor was too costly. So now I'm looking for a way to mount LED strips onto the decking under the railings, with the light directed down towards the wood.
I guess the simplest option would be to attach a wood strip maybe 1/2" above the deck and mount the LED strip under that. But I worry this might look a little clunky, and might be hard to maintain.
Another option could be some sort of metal channel that could be thinner and less maintenance-intensive than wood.
BTW, if I can't figure out a fixed-enclosure solution, we'll probably go with some sort of very long string of very dim rope lights, e.g. https://www.amazon.com/dp/B07MHDW44J or https://www.amazon.com/gp/product/B08HYZF3LV, which won't be as fancy but will be a lot cheaper! ;-)
