Need Electronic Schematic Help for LED lights

[omegacerberus]

Please see our proposed design listed below:

And let me know if my voltage and resistor calculations are correct. Also, let me know what I would have to change if I used 2 bulbs instead of 6, or even 16.

This is a design based upon the design by Fabio/Kaotica located here:

Thanks in advance!

Your calculations are sound. You could have up to 15 LEDs (limited by the 300ma available). Just be aware that most of these supplies are not regulated, and the output voltage will decrease as the load current increases, so each individual LED will be dimmer if you connect more of them. You will probably get more than 20ma per LED under light load with the resistor value you calculated.
