So, I just printed this riser and having had an issue with where the light was beaming on another project, would like to hear others thoughts.
I sketched up the dreaded PowerPoint to show the options as I imagine and feel free to opine.

nice, but little bit confused, what is the application of this COB
Throw light into printer.
Drawing not to scale in slightest.
Not a big deal. I made wedges that are the length of the sides of riser so if flat doesn’t work, I’ll mount wedges to angle COB strip downwards.
Same principle as the light BTT sells for P1S
Well, I thought you were studying COB. I’m currently studying a bi-color COB.
Do you have any recommend
I had some plan in mind like this as well but 24v led strip instead and tap onto the 24V power supply of the printer.
My plan was to have some bracket that bolt to the frame
But since I bought P1S, I had to keep reminding myself: my P1S is not THE PROJECT, it is THE TOOL to make other projects. So, I am kinda lazy doing this 
I hear you. The reason I bought my P1S was I wanted a tool for projects. The Ender-3 Pro was a never-ending project.
In defense of the lights though, the tinted front door and removable top cover which may or may not have an AMS on top, visibility inside chamber is terrible so A find myself using a small desk lamp to work on printer if it is idle and using that same lamp but outside the chamber if print is running.
So, fundamental difference between my creality where I was buying parts with abandon in hopes it would even run, much less print something useful.
So I see the 24V lighting as a good enhancement to a good printer, thereby making it better.
About the tenth time I heard:
Man, that Bambu Lab printer just runs and runs and runs
I was done with that Ender because NOTHING could be worse than that Ender.
At this point, after trying two different varieties of LED’s before buying the COB’s off of Makers World based on a recommendation from forum, it’s about K number (for me 6500k) and Lumens. More is better but often hard to ferret out that number and how it is defined. Some define over the length of entire spool, some lumens per meter, and others lumens per foot so make sure you are reading the same lumen number comparison be it per foot/meter/roll across the various offerings
