How i can make this emergency lamp flicker..Anyone know....I mean first lamp on,second lamp off,then second lamp on,first lamp off..flicker..Anyone know....
why would you want to make an emergency light flicker?
Emergency lights are normally used if mains electric fails. Making the light flicker will certainly cause panic amongst the people in the room where the light is activated.
You might want to increase the psychological effect by simulating a burning transformer and generate smoke and noise.
I don't really understand why the light should flicker.
Sounds like he wants it to flash alternately, not "flicker" per se...
Does it have a separate ballast for each tube? If not, you'd have to do quite a bit of modification to it. Otherwise, a flasher circuit w/a 555 timer and a SPDT relay could do it.
