This is not anything to worry about - just more annoying! The glowing or flashing effect is reported on this forum quite often.
It's most likely due to capacitative coupling from permanently live conductors inducing a voltage on the switched lighting circuit, which is causing the led's to glow. A solution is to reduce that 'ghost' voltage by fitting a 'snubber' device between (switched L) & (N) at each light fitting afflicted with the glow!

Thanks mate . it's been doing it for years . I'm sure I measured a small amount of volts with multimeter when I removed a lamp and this increased to 50V when I switched on the light next door.
