The Philips MI50 was the precursor to the MI26. The general shape of the lantern is similar to the Thorn Beta 5, but it has a more-squarish appearance. It's canopy is made from diecast aluminium, with a polycarbonate bowl. The bowl would also be used on the Philips MI26. The lantern can come in remote or integral-geared versions. The MI50-OO is the remote-geared version with the MI50-GO being the gear-in-head version. This is the latter.

The installation was a rare example of an MI50 with neither of the grubscrews seized. To top this off, the bracket wasn't seized either!

With the bowl opened, the acceptable condition of the gear tray is apparent.

The identification sticker is in good condition.

The gear is also in good health, minus the singed 6.5 micro-farad capacitor. Around the ballast, an area of yellowing can be seen due to continuous heat-exposure. The ballast-holder's paint has also started to come off.

After a thorough cleaning, the lantern was re-assembled and powered on. The lamp sprang into life with no issues!
