Review on 🔦 Jorunhe Vintage Ceiling Spotlight Fixture: Industrial Metal Pendant Lighting with Adjustable E27 Spot Light - Fixed Style by James Prizgint

First you need to find a lightbulb. It's 110v, not 12v. I took it to a specialty store and the PAR16 LED fitted perfectly. However, adjusting the light proved to be problematic. I had a ceiling outlet, but the socket that came with it was too small. I ended up having to drill a plug and attach a lamp to it. The lamp wiring was connected to a terminal block inside the fixture but the wires fell out during installation so I removed the terminal block and used rotary connectors. It worked, but the cord on the lamp was very short so there couldn't be a fault. In general it is quite difficult to install. I suspect it was made for the European market and modified for the US market.
