Re:
Hi Selfbuilt, and thanks for the great review. I received a predator PRO with warm tint earlier this week. This is an excellent flashlight with a comfortable hold and an awesome tint. Also it's a really great thrower for it's size.
I did some runtime tests with different batteries:
*2RCR123 Tenergy LifePO(640 and 190lm)
*2CR123 Titanium Innovation double pack
*AW 17670
*EagTac 3400mAh
With all these cells I had a step down of 18-19% after a while. But still I think the setting is FULL brightness; it didn't really behave like the STEP down in your graphs(no 3flashes with CR123s while 2 times with Li-Ion 3400, didn't try 17670 so far).
Tenergy LifePO: stable output at highest level for 16 min, then an instant drop to ~81%, a few seconds after that an instant drop to firefly level.
Updated: At 190lm mode(~140 OTF lumen) I got 95min stable output until 3 flashes and then drop down to firefly level.
Titanium Innovation: stable output for 27min, then instant drop to ~81%. Then stable at that output until 33min 45s, followed by instant drop to firefly level
AW17670: stable output until 15min, then instant drop to ~81%, then stable at that output until almost 39min, 3 flashes and a drop down to ~64% of initial brightness. I stopped the test at that moment.
EagTac 3400mAh: stable putput until 15min, then instant drop to ~81% until 66min, then 3 flashes. and a drop down to ~64% of initial. This time I let the light go on. It continued at that level until 80min. Then a second time 3 flashes, directly followed by an instant drop to firefly level.
To be honest I am a bit dissaponted with the runtimes of this light, it' not close to what specifications could make one to expect. Also the advanced manual(not included in the package) I find horrible complicated to understand. I really would like this light with only a few simple modes and nothing more.
About the batteries I am surprised that AW17670(1600mAh) provided more than half the performance of EagTac 3400mAh. Especially when I take in consider that the 17670 I used in this test isn't recently charged, it's some month ago, while the EagTac 3400 was charged yesterday.
Because the drop down to ~81% still means around 400 OTF lm it's not a big issue for me. It's a supreme thrower anyway...
I welcome your thoughts about my results.
