Hi DerStrom8,
If only I could use the bigger cement type, but I need 16 of them and I would need a shoe box for the circuit.
Hi Ron,
I did mention that I am switching them through a ULN2803 which drops the 13 volts by 1.4 or so and the LEDs are 3.6v, leaving 8v by 33r =242mA and amps at 1.96 I think. But the problem is that I need to run 16 of them too, all separately for patterns so I can't series them.
I am thinking at the moment about a switching supply maybe of about 4v at 6A. It would be more efficient but it would also be my umpteenth attempt at a SMPS with all the others being failures.
Any thoughts? Al
