I didn't mean to suggest that there was anything wrong with your "one-segment-at-a-time" design Melanie. You designed the product for a particular current budget and brightness level and that's fine. I simply wanted to mention that your statements might mislead other Forum members when you ignore "duty cycle" and its effect on average current and brightness in your statements.

I've tried this method and it works great but performance drops considerably as you add more LEDs and decrease duty cycle.

Kind regards, Mike
