Hi all, i have made a few led boards and i now would like to if possible make an led board that would turn its self on when it gets dark and goes off when its light is there some kind of sensor i need in order to make this work

Don't play with mains as it can be lethal. The good news is LEDs are low voltage devices so you could use an AC adapter to bring the mains down to safe levels.
hi, thanks for the help guys and im not playing about with the mains the leds run off 12 transformer, i still dont quite understand as i always use 12v dc tranfrormers i was told that ac would not work
Good thing its the Christmas season... Look around, you should find a device that turns on your lights at night, and very cheap... Just make sure it's the simplest one, there also some with timers, some withe remote controls.
Could also search here or the web for a dark activated switch. Not sure about a 12 volt version, but remember lower voltage.

Is this something written on the power supply module OR Transformer? Have you made the LED boards yourselves? Can you say how many LEDs are connected in series?
hi yes i made the boards my self a frend told me how to do it eg resistors ect and i have a pic of how iv done it if you would like me to post them it was my first one so i know iv probably done it badly but it works
also for got to add yes thats the info on the power supply

I presume that you use a DC power supply for driving the LEDs and want to switch ON/OFF automatically by sensing the light (please post diagram, if available). Will try to get one circuit for this.
