I am using a White Seoul P4 LED. I plan to direct drive it using only a battery (9v unless someone has better advice) and a resistor. I have been searching the forums and have been unable to find what resistor the Seoul P4 needs. It's not even on the CSS's LED value chart, unless it correlates to some other LED's specs that I haven't been able to determine.
The Seoul P4 would be similar to the blue, green, and white lux III on the chart.
You can also use this calculator to figure the resistance.

Go to Seoul's website for any specs you need on the P4

9 volts is quite a bit more that you need, and 9 volt batteries have very low run times. Try using a 4 AAA or AA battery pack.

Personally, I suggest using a buckpuck instead, it provides much better results. Just my two cents.
I agree.... but if your on a tight budget use a resister.... resistor- http://www.thecustomsabershop.com/22...stor--P11.aspxQuote:

And forget about using a 9v battery if you can fit a 4aaa pack.
