FUNCTION
It has four levels of brightness and a S.O.S. and strobe setting as well. The light has two modes of use. A general mode and a Turbo mode, so the light can be turned on in either the dimmest level of output or the brightest depending on whether the head is screwed all the way down or not. A slight press (not click) of the tailcap will move the light to the next level of brightness. If the light is accidently clicked off (instead of slightly pressed) it will turn off. If you click it back on in less than two seconds it will turn on in the next level, but if you wait more than two seconds it will reset. The levels function in this method:
Turn head 1/4 turn counter clockwise: Low,Medium,High,S.O.S. (repeat)
Head tightened all the way: Turbo,Strobe (repeat)
OUTPUT
General Mode: 12 lumens (low) -> 53 lumens (med) -> 120 lumens (high) -> SOS
Turbo Mode: 215 lumens (Turbo) -> Strobe
These numbers are taken directly from Fenix. They tend to be a little high, but expect them to be rather close to the real amount of lumens coming out of the front of this light. The output on low is rather low but still enough to walk around inside a house or for up close work output, while the output on turbo is shocking.
I have a Lux meter and took some readings. The first reading is a Lux reading of the center (hotspot) of the beam. The second reading is a lux reading of spill beam of the light. The third reading is from doing a ceiling bounce and checking the light meter to determine the total output of the light. The number itself means virtually nothing, but it does show exactly how much brighter each setting is from the one before it.
P3D Q5:
Low:
140 Lux, 10 spill, .8 overall
Medium:
730 Lux, 40 spill, 3.6 overall
High:
1710 Lux, 70 spill, 8.1 overall
Turbo:
3050 Lux, 150 spill, 15.2 overall
L2T V.2 Rebel 80
Low:
260 Lux, 10 spill, 1.1 overall
1,900 Lux, 50 spill, 8.0 overall
As you can see the P3D Q5 is nearly twice as bright as the L2T on high which is rated at 135 lumens and was tested at over 100 lumens by another very knowledgable member. Keeping that in mind I would estimate the P3D Q5 to be around 190 lumens or so out the front! :rock:
RUNTIME
65 hours @ 12 lumens on Low
13 hours @ 53 lumens on Medium
4.8 hours @ 120 lumens on High
1.8 hours @ 215 lumens on Turbo
These numbers are taken right from Fenix, and are done with two primary CR123 cells. For the most part they are pretty identical to how the light will actually perform, and in some cases a little short. Usually you will get more than their quoted runtimes on the Low and Medium settings. The light uses constant current regulation so you will have perfectly flat runtime (no dimming) without any flickering at all on the low modes which is associated with PWM. Very efficient.
SIZE/WEIGHT
The light is 4.5" long and is .8" in diameter. It weights 2.8 ounces or 81 grams with batteries installed.
Considering that it is a 2 x CR123 light it is very small. The light feels very nice in your hand and is easy to hold. I would consider it pocketable in a coat pocket or a deep pant/cargo pocket.
BEZEL
It has a UCL lens with AR coating and has a very nice textured metal reflector. In my specific unit the LED is very nicely centered. Fenix has had problems in the past with off center emitters, but hopefully they have corrected this or at least cut down on the problem.
BODY/TAILCAP
The entire light is made of aircraft grade aluminum and is coated with type III hard annodize. This makes the light quite a bit more durable than your average flashlight. The body is very steamlined and sleek in appearance. It has some knurling to improve grip, but honestly it doesn't do much of anything since the light is rather slippery, and the knurling isn't aggressive enough.
The tailcap is a reverse clickie and has a nice textured rubber boot. It has two small holes for installing a lanyard.
OTHER
The light is waterproof IPX-8 standard.
The tailcap is recessed so that the light can tailstand to act as a candle in a room/tent/etc.
PROS
Great runtime, amazing brightness, small/lightweight, good build quality/finish, multiple levels of brightness, very white tint. Nearly everything!
CONS
If I had to list one I would say the light could be rather slippery if it got wet. Because of this I recommend using a lanyard if there is any possibility of the light getting wet so prevent the possibility of dropping the light.
