What is the best way to turn off LEDs?

[davidm]

A quick Qu for those with LED or electronics experience -

 

When it's time to turn the LEDs off for ~12 hrs, would it be better to shut off the 120V power supply to the driver and leave the dimmer circuit receiving 10V, or leave that 120V power supply to the driver on and drop the 10V input to the dimmer circuit to zero? Either way obviously shuts the LEDs off, but which would be 'softest' for the driver and LEDs?

 

thanks, david

As long as they're going off for a long period of time it's best to kill the power to the driver. Otherwise you'll be leaking power and have a constant current draw.

There is a catch. I just don't remember exactly what it is. IIRC you shut off the 120 volts the lights will flash as the ELN shutdown. So shut off the 10 volts wait 10 minutes then shut off the ELNs.

 

Something like this anyway. Experiment once you get one string up and running.
