Blooma Komet bulkhead.

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.

When unlit, there's no way of knowing the conversion that's been done to it. The cover is rather poorly designed however, as it has 3 pairs of plastic prongs that slot through the base casting, being secured shut by unscrewing grub screws through between them. I've already accidentally broken (and repaired) 2 or 3 of these prongs.
