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

Question

May 220 Volts rated L.E.D. lights designed for use in Germany, flash on and off on U.K. 240 Volts?

LED lights for both Germany and the UK should be rated 230 V. Table 1 of BS EN 60038 CENELEC Standard Voltages . Manufacturers are pointed in Clause 4.1 of the standard, to the fact that the supply voltage (at the origin of the consumer's installation) will have a variation within &plusmn; 10 % (in the UK, according to ESQCR, it's + 10 %, - 6 %), and that there will be a further voltage drop within the consumer's installation according to HD 60364-5-52 (Chapter 52 of BS 7671 in the UK). In fact, 220 V is not an IEC standard voltage either (IEC 60038) ... for 50 Hz supplies, it's still 230 V, which means that the lights are not produced for a country that follows IEC standards either. So I would either not install them, or query the voltage with the manufacturer. The standard voltages have been that way for some very very long time.
