Use the legend below to quickly select the driver with the features that you need. So if any one could please give me advice as to what batterys i should use and point me to some good cheap drivers for them. We were discussing about using LED drivers for powering up 445nm diodes, and even someone mentioned that will try to use this cheap boost driver. Ic Wkn The second draw back is that DMX LED drivers are Pulse Width Modulation.

They are going to be using a low frequency pwm and that will show up in scanning. Sign in Transcript Statistics Add translations 268,505 views 668 Like this video?

Even tiny increases above the threshold current can bring about a considerable increase in output power and a rapid over-shoot of the optical output power critical value.

The showerhead host I got is direct drive, I just imagined that lights with higher performance LED's would have some kind of driver. The main reason being, that LED drivers, especially the ones controlled via DMX normally depend on the LED's to have their own current limiting as most LED strips do. Either an automatic current control circuit combined with a temperature regulator or an automatic power control unit is required to guarantee maximum lifetime and stable operation. LDs are sensitive and we need to check driver with oscilloscope to see how stable it is.

So sorry is this information is spread around i found some of it but i still had some questions. 1. R. If the spikes are there, they will occur on each and very PWM cycle or transition, resulting in a very short LD lifetime... http://www.dealextreme.com/p/2-7v-6v-3w-cree-circuit-board-for-flashlights-15mm-2-7mm-25518 Um, I'm pretty sure driving 700 mA of current, through a laser diode that can only handle 170 mA max, will destroy it.
