Someone asked if my MR16 superflux PCBs would fit into the integrated downlight unit, and the answer is yes. They won’t clip in, but they could be tacked in with hot melt glue.
However, while checking this I suddenly realised that the LED lamp industry is using the round PCB it uses in MR16 and GU10 sized lamps as a standard size that fits into these downlight units and some globe style lamps.
I duly modified the 110V lamp that I recently completely destroyed the base of while opening, and after fitting it with a 400V 220nF cap and new leads I clipped it into the downlight case. it’s a perfect fit and provides a good even wash of light.
This does open up some possibilities for hacking and modding other LED lamps or even making custom specialist PCBs that fit in the downlight case.
