Can a Prop-1 power a 12V 35-Watt low voltage landscape/Yard light?  I am looking into alternatives for having a bright light that does not require a 120v plug.


Anyone know?

Sorry, no.  The ULN spec says 500 mA tops and your bulb would be pulling about 3A -- if you hook it up you will definitely "let the blue smoke out" of the ULN.  Have you considered LEDs?

I belive that would be a 2.91 amp load, which would far exceed the capability of the uln.

You could use the Prop-1 to contol a 12v relay which turns on and off an external 3 amp power supply.



Edit: Jon beat me to it.
