Thank you so much for the detailed explanation. Of course the main attraction with that MOSFET was the RDS(ON) as I wanted the chip to stay cool. It appears to be driving the tiles quite nicely though I will take some measurements this afternoon and see how the voltage drop compares to the datasheet :) ..

.... okay that's simple .. just connected up a TCET1101 and it worked like a charm! :D



Nothing to stop me doubling this up for each LED.

No sweat :)

You know what they say: 'Those that can do, and those that can't advise others' :palm:
