More decorative items today.


It’s tree lights. Good, old fashioned filament lights, 20 lights for £2 from the local cheap-shop. They make more interesting images than LED lights do, there’s contrast from the lead-in wires and the filament and the enclosures. LED lights are usually just a plastic package with a tiny active part inside, much better for reliability and energy efficiency, not very interesting to X-Ray.
