    Default mistake on leds

    Just anyone out there making a led system hears a simple note for you

    NEVER PUT A ON OFF SWITCH BETWEEN THE DRIVER AND LEDS

    you will regreat spending $100 of dollars on leds to see them all dead

    Doesnt matter... with constant current drivers, you need to turn the DRIVER OFF, not the led's.

    Im not an electrical engineer but it has something to do with the "constant current" and how that circuitry is used. The driver needs to soft powered on.

    I think when switched off it is pulling 0mA. Then when you switch it on, it sends more than the 700ma through the pipe line frying all of the LED's.

    most switchs are rather simple , there really is no way to blow the switch as most of them dont have anything electrical. the switch just basically moves the current from off to on with a piece of metal.

    Adam has it right, the drivers are a slow start up basically go from 0-700ma, with the switch its a one shot of 700 and blows the LED's.

    So would it be fine to put the swithch between the drivers and the power source, or the power source and the plug outlet? From my understanding of what i have read here both should be fine, Just wanna make sure cause i am in the beginning of my own LED build.
