I too have a PIR connected so it is only ever on when needed, direct drive and PWM is available to dim if required. At 30 seconds past it does the date/temp etc thing - but as it is only a four letter word clock, I was thinking of putting a word up every 15 seconds. Is that too many, too few or about right ? - Richard
