I did a lighting job in a model period house that we installed in Hever Castle. They have part of the bookshop set out as a museum display on the evolution of castles and large houses over the years  and the model we installed was part of it. All the models were very detailed with windows or cut aways to show what was going on inside. Lots of the models had chandellers with tiny lights to illuminate the rooms. They looked pretty but as general lighting they were useless.

I was asked what I could do to improve the lighting.

Remember this was in the days long before  white LED lighting and I devised a strip light made with lots of 12V festoon lamps. I made units 300 mm long housed in a metal channel about 8mm square. I designed dimmable power supplies to drive them and installed 20 or so in all the models. As they were filament lamps they had to be easily accessable for lamp changing and I popped back each year for 10 years to keep them all going.  These photos were taken on my first digital camera, an Olympus C1400L SLR with not a very good white balance control.  Looking at the frame numbers I can see they were the very first photos taken with the camera.
