I've got a few old 220V CFLs that are burned out. Usually it's the driver circuit that fails.
The folded up tube themselves have 2 connections at each end, just like FLs.
Could I gut the old 220V electronics from the CFL, put in your FL-driver, and end up with a serviceable 12V CFL? If so, I think I've just found a good use for old defect 220VAC CFLs...
And, for clarity, the CFLs (E27 base) that I'm talking about have a total of 4 connections to the actual tube, 2 at each side, just like plain FLs.[ Parent ]
