Re: power swicth

yes the lamp should flash every 1 microsecond of course it's the maximum frequency. and that frequency could variate between 1mhz and 1khz
the purpose is to change the color of the emitted light .

purpose is not clear.
will you be able to distinguish its on/off time with your persistence of vision.
you know at what frequency your normal house hold ac lamps swithches.. and are you able to make out its on/off conditions?
