led and radio buzzing

[John Bunning]

hi fitted some of those new leds in a kitchen.all ok till the guy purchased a new dab radio. found that the led cause buzzing on the radio. revert back to standard lamp ok.will led work any better with dedicated 12v dc drivers ? ref noise.will prolong lamp life yes ?. bit tricky as the kitchen is installed with track and clip on fittings ? .
i like leds but i think there a long way to go
