Blooma Komet before conversion, internal layout.

I completed this conversion seven years ago now, but its one that's always stuck with me considering its large size and what it originally was intended to run. Bought as a 60w GLS bulkhead, I saw potential to convert it to something more befitting for its size. I already had a spare ballast lying around, and buying in the correct lamp connector with built in starter socket, this conversion was completed rather quickly. Now sporting a 22w circline lamp, the fitting looks absolutely incredible when lit, there is absolutely no dark patches cast from the plastic shield, and the fitting runs very cool too.

before conversion, the fitting looked rather bare inside, featuring nothing more than a lamp holder and a terminal block. Seeing the large rectangular recess in the metalwork prompted me to attempt to see how a EC30 ballast would fit, and shockingly it fit comfortably, with both tapped screw points matching the holes in the ballast. Whenever I convert, I like to make sure I don't modify the fitting at all, so this was a very straightforward conversion in the end.
