darren, the bulb is switching at 50Hz or 60Hz depending where you are in the world, as are CRTS, hence the flicker. If you turn the bulb off and swing it, no flicker.
The frequency at which a flickering source is perceived as continuous is called the flicker fusion frequency and starts to kick in around 16Hz though varies with brightness, fatigue and even the bit of retina the image falls on, which is why some people can notice the flicker from stataionary tvs when they are on the edge of their visual field. The flicker is really there. -- JezA ------------------------------------------------------------------------ JezA's Profile: http://forums.slimdevices.com/member.php?userid=21219 View this thread: http://forums.slimdevices.com/showthread.php?t=57631 _______________________________________________ audiophiles mailing list [email protected] http://lists.slimdevices.com/lists/listinfo/audiophiles
