Solution for indirect lighting from top of bookcase

Hey all. I have a room that's currently lit (during the night) by two light fixtures attached to the same wall and on the same switch. Each fixture has two LED lights with a 2700K or 2800K color temperature (don't remember exactly), 230lm brightness, 3.9W power consumption, for presumably a theoretical total of 920lm and 15.6W. These bulbs are angled some 45 degrees forward aimed at the (white) ceiling in order to reflect diffuse light for the rest of the room.

I'm going to add two tall bookcases to that wall which are going to cover where the lights currently are, so I need to figure out another solution for lighting. I don't want to damage the ceiling. Currently, my idea is to extend the wiring from the walls up behind the bookcases and place lights at the top of the bookcases, similarly angled forward so they reflect off the ceiling closer to the middle of the room.

But I'm not finding appropriate fixtures, devices or anything else that I can place on a horizontal surface in order to angle a directed diffuse light forward. The closest I have right now would be something like these outdoor waterproof floodlights.

They have a number of problems, though, chief of all the temperature being 3000K (that's the lowest available; you can get them a lot colder). For some reason, no one seems to be making 2700K/2800K versions of these. I'm afraid if I buy these, the light in this room will be noticeably different from the rest of the house. They are also very bright at 1000lm each (these are the darkest available; they make them even brighter) for a total 2000lm, more than twice the current brightness. I'm afraid if I sit in a room lit by these, it will affect the quality of my sleep.

Does anyone have any ideas that might yield something closer to what I currently have, but which can be placed atop the bookcases and directed forward and up, as desired? It's also important that replacements don't require waiting for a 6 week cargo ship voyage from somewhere in China, that the power consumption isn't significantly higher, and that there won't be some huge monstrous device on the bookcase visible from the ground.
