Default Mode driver?

I don't know much about drivers. I saw this on DX. How well will it work? $2.60 - 3.6V 5-Mode 3W Circuit Board for Flashlights (1000mAh 3.7V Output) - Flashlight Parts and Tools

How well will it work for what?

For a 445nm it doesn't output enough voltage for the diode's full potential.
For any other diode, 1000mA is so much current it ill die instantly.

It looks like a 1000mA fixed linear driver with pulsed modes.

Thanks but i found a better one. What voltage is needed for a 445?

Default Re: Mode driver?

Depends on how much current you want to drive it with and the efficiency of your particular diode, but somewhere around 3.7~4.3V.

Don't you know?
You should, you've build one if IIRC.

Default Re: Mode driver?

In that case you put "if" twice
Anyways for all my builds I've used drivers meant for lasers. I want to use an LED driver with modes. Will this work? $3.19 - 5-Mode 1000mA 7135 Circuit Board for Cree and SSC Emitters - Flashlight Parts and Tools

EDIT: You beat me to the correction
