Just curious to know if anyone has had trouble with the above in relation to HI-FI remote controls. My remote (Quad) refuses to work on the "stand by" or "volume control" buttons when a nearby low energy bulb is switched on. All other buttons / functions work O.K.. Switch the bulb off and everything is working again. I guess that there is some infra-red interference generated by the bulb. It is worse when the lamp is fist switched on, i.e. cold. Other than ditch the bulb is there any other cure (apart from sitting in the dark) ? Pete.
