DX 7880 & 7882 Board questions

[kosPap]

On the DX 7880

well I have installed one before making any measurements whne I measured current draw on the flashlight I got a max of 0.6A which is very low for this driver (LED output was proportionate).

What can be of fault? the driver itself?

On the DX 7782

How exactly do I setup this driver? Do I measure Vf and Af with the LED connected or not? How will I compesate from DMM losses?

Once installed I want to cover the exposed components around the spring of this board and similar others. What material is optimum to use, and if not what would you suggest of the following?
- Araldit 2-part epoxy
- Miliput Epoxy plaster
- DX thermal glue (the one that is used for mounting the LEDs)

Thanks beforehand, Kostas

Is it possible that the UI is in one of the lower modes?

My 7880 draws about 2amps from an Eneloop. I soldered the negative wire to the rim to bypass the UI, so it is now a 1 mode driver.

I don't have a lot of experience here, but I've used 2-part epoxy to protect components inside a light. It seemed to work just fine.

No...rge Ui changes groups as speced.

I have confirmed the current draw in the highest mode.
Did not think of trying wiring it single mode...
