I loathe those "too cheap to be designed for minimum durability" products. However, resistors are usually a lot cheaper than LEDs. Each LED comes with its own resistor on cheap LED strips from china, sometimes resistors are even integrated in the LED packaging. As for PWM -- do you have any source on this? I guess you just have to take into account the capacitance of the LED?

>As for PWM -- do you have any source on this? Well, mostly just "duty cycle" related. If you're pulsing the LED half the time (50% duty cycle), for example, you can pulse with twice the current you would normally use if it weren't pulsed. Then you control brightness by pulsing for a lower percentage of the time.
