While things have been off and on lately, I have finally managed to get the LED strip installed on (in?) the valance and wired up. The wired up part is only to the valance end as evidenced by the unsightly cord and power brick perched on the layout at back right. It should not take much more effort to get some concealed wires going down the back of the wing. I just need to settle on how to get from there to under the layout in a easily disconnectable manner.
I am happy with the lighting result but the intensity is on the weak side for photography. I will almost certainly add a second natural white strip in the not to distant future. I might make it switchable so I can vary intensity to suit.
I think that I will next have a go at complete the basic landforms and roll right into mocking up buildings.
