I have stuffed the board with 24 super bright LEDs. In fact I have reused the old ones that are still good. They have a warm tone I prefer. You can see the daughter board "on-edge" in this shot. It has two brass lugs that twist and lock into the power buss holders. The holders can be strung with connecting wires so you can have a string of up to 8 (or more with a higher amp transformer) in series.





A side by side comparison. The one on the left is the new design using the warm LEDs. The one in the middle is using the cooler blue LEDs running on AC. And the one on the right is the AC warm LEDs. I can't tell any difference in brightness between the two warm ones like I thought I could. Since I ran out of the cool-colored LEDs, I can't do a full comparison with those yet.




Milled another 2 boards (total of 5) but am only using 4 right now. Measured the current at 285.5mA (~72mA per module). The transformer is rated 9V 1A, but the voltage is 10.71V. That is 3.05 Watts. Compare that to the 18W package marking.

Things are bright and easy to see again. Now I can get back to my projects.
