Wolf-Eyes Defender-II D2AX-II Cree P4 HO mini-review (runtime updated)

EDIT 7/8: Added runtime of High mode using LRB-168A
====



Got this great light from the raffle: QuarterFlash/LumensFactory Raffle!

Thanks Glen C for this wonderful offer! :twothumbs



The discuss thread started bt KeeperSD is here: New Wolf Eyes D2 with 2 level cree - pics/beamshots
I'll just take some photos at this moment, runtime will be upload in a few days.



Spec. summary:
Cree XR-E P4 3.7~6V D26 lamp assembly
Two-stage output: 170lumen/20lumen with HO lamp assembly
80min regulated output for High output (4 hours un-regulated output)
50 hours for Low output

Deep sculptured head bezel:

LED is centered well. The reflector seems to be heavy orange peel.

Included LRB-168A

Apart:

I haven't seen such tube construction before. Double layered? oo: Brass for inner tube?

Head end:

Tail end:

The switch is forward clicky. Soft tap for momentary ON. Full click then release for steady ON and one more click to OFF. Twisty head for High/Low. The operation is simple.

The included WE LRB-168A works fine but I have problem with AW protected 18650. It'll be only in Low mode. I found LRB-168A is slightly longer than AW 18650 and I put a small magnet at the bottom. The problem solved.

Here's some size comparsion:

The output is bright and white! Please refer to KeeperSD's thread for great beamshot.

Here my poor beamshot :devil:

Low mode (M1 on the left, Defender-II on the right)
E.V. +0.0

E.V. -1.5

High mode (M1 on the left, Defender-II on the right)
E.V. +0.0

E.V. -1.5

Lux reading at 1m: High: 2580, Low: 209
My M1 with OP reflector: High: 3710, Low: 772



========
EDIT 7/8: Added runtime of High mode using LRB-168A

Here's the runtime of High mode using Wolf-Eyes LRB-168A protected 18650. The marked capacity is 2200mAh. Runtime started with open circuit voltage of 4.20v. Flat regulation about 110min.

Well done on the acquisition Netkidz, hope you enjoy the light. I love mine it is a great light, has taken the place of my Incan sniper as my go to light for around the house. Is this your first Wolf Eyes? Nice collection of other LED's you have there too i must say.

Hello KeeperSD,

Yes, I like this light and it'll replace my Lumapower M1.

 

[NetKidz]

Updated runtime of High mode using Wolf-Eyes LRB-168A. I'll not do the low mode runtime since it'll be a very long run.

The wait for mine will be looooooooooong... Nice review! I ordered some Ultrafire 18650 for mine there:

I think they are button-top. I hope there won't be any problem with those.

What is the open voltage of the cell when it drops out of regulation? I wanted to know if it dimmed before being cut-off by the cell protection and from what I see on the runtime graph, it's a great news!

Thanks

There's spring at the positive contact of Defender-II (the lamp module), thus flat or button top won't make difference. The problem is the length. Like I write, if the length isn't enough, it'll only in Low mode.

No, the protection PCB havn't cut out. I stop it manually. I didn't measure the final voltage. Anyway, if you feel it start to dim, change or charge the battery.

Yeah! I understood that but usually, button top cells are slightly longer! Anyway, I hope the UltraFire cells will be long enough!

I'll check that when I get the light! I've read that it is a good practice not to let the protection kick-in before charging.

I have a few questions before this, is there any performance difference between the 2 CR123's or RCR's or the 1 rechargable cell

also when going here

http://www.pts-flashlights.com/products/productList.aspx?uid=1-3-89

it states the bulb is 100 lumens, is it really 170?

dont wanna sound too nieve but thanks

100 lumens is probably for the incandescent lamp assembly.

with 2 CR123 you get less regulation time but longer "moon mode". The best regulated runtime is acheived using one 18650 Li-Ion cell. But it seems you get less "moon-mode" time. As for using 2xRCR123A, I'm not sure if the LED lamp assembly will take the voltage (8.4 fully charged). The lamp assembly is quoted for 3.7V-6V (1 Li-Ion or 2 primary CR123A).

so if i get the defender II i probably would haveve to buy the drop in CREE P4 XRE 170 lumen bulb? sorry for all the questions

also i might want to use RCR123's would i want to purchase the 3.7-13V bulb over the 3.7-6V bulb? thanks a lot.

The Defender-II comes with the lamp assembly. I don't know if it'll damage the lamp using 2xRCR123 for 3.7-6v lamp, but I definitely won't try it.

You could ask Mike@PTS for correct lamp and order information.
