Just got an Armytek Wizard Pro V2 warm white. I chose this one because it's the only warm white Wizard Pro that will run on CR123s and RCR123s. I prefer to power it with 18650s but I stock CR123s for extended blackouts (which never happen where I live, but still).
The output dwarfs that of my Spark ST6-460NW (which flickers on the lowest and highest levels when running 18650s), the color rendering is VERY nice, the runtimes are decent, the mode spacing is ok and it is very comfy to wear. Also, it is nice to have the power indicator. On the max mode it's not a room lighter - it's a barn lighter.
In short I LOVE this headlamp.
Yes, I have a couple of multimeters. One old analog Radio Shack meter and a cheap digital one. I removed the tail cap. Placed one probe (ended up being the black one) on the back of the battery and grounded the other probe to the headlamp body.
Using the digital meter, on the 20m scale, the ArmyTek went to 7.5. I think that's 7.5 mA? The old analog meter appears to be showing about the same.
I have a Nitecore HC30. Did the same test. With the Nitecore the meter flicks up to about 1.5 when the probes first make contact. Then the meter drops to very nearly zero over the course of a few seconds.
I've never done a parasitic test before. Isn't 7.5 mA kinda high?
