If L.E.D. lights rated at 220 Volts are supplied at 240 Volts will they perhaps flash on and off?

The decorative L.E.D. ceiling lights were supplied by the customer and the box rates them at 220 Volts. I queried this with the customer but was still asked to fit them. Their flat is in a new build so the supply Voltage may be high.

Perhaps, as I had a similar problem to this with some dimmable Osram/ LEDvance LED filament lamps - actually they would run, but only for about 15 mins, then start to flicker and got very hot at the base with the electronics - which said thermal overload to me. As they were mine at home a bit of experimenting was in order, and I found  they will stay on either with a conical sheet aluminium heatsink clamped to the outer of the B22 base, looking rather  like those collars that vets give to poorly dogs to turn them into a megaphone, or more practically with couple of hundred ohms in series (suiatable rated - no miniature parts on mains please !) to dump 20volts or so, which I have hidden in the base of the fitting. So far several thousand hours later, with the resistor mod, running cool and still going strong. Whe one fails I will crack it open and see what is within, but being tight fisted I do not want to do that to a working one.

Neither of those ideas would be a good solution for customer equipment, but it does suggest that at least one reputable make does not run long term tests  over the full 207-253 volts that they really should for CE marking . Perhaps other makers also do not.
