No idea, as I've no idea how that light works with the 505 either. But how would it be different with a clip-on-light? If you shine downward, it should reflect off the e-ink surface, just like all light. But, with a clip-on-light, you need a fairly bright source of light because a lot get lost to the surrounding area. If you make a rim, with more smaller lights, the individual lights can be dimmer but the total would give the same amount of light.
