The Fenix P2D is the C123 version of the Fenix L1DCE. It has the same user interface but uses a C123 lithium battery instead of the AA battery used by the L1DCE.Both lights use a Cree LED, so they are extremely bright for the size with very good balance between throw and side spill the hotspot is very strong and the spill is really usable. As in other Cree lights the beam has some artifacts and will not be very pure against a white wall but that causes no problems to use the flashlight.
The light has two modes of operation depending on the position of the bezel. In each mode of operation you can access different submodes using the reverse clickie switch. With the bezel in the first position you turn on the light in "turbo" mode (max brightness), a light tap in the switch then moves to the strobe. With the bezel in the second position the light is turned on in minimum brightness, the you move to medium, maximum and finally SOS mode clicking the switch.
From any mode you can twist the bezel to go quickly to either maximum or minimum brightness, this is what makes the interface very nice to use.
The P2D uses a C123 lithium battery and reaches up to 100 lumen in "turbo" mode it can use rechargeable 123 batteries but you lose some of the modes until the battery voltage drops a little.
The head of the light can be used in a P2D or L1DCE body indistinctly so if you get one and an extra body you have both lights, the reverse clickie switch works in both flashlights.
Both lights are constructed in HA-III aluminium, very strong and will resist drops scratches and impacts. The runtime is about 1 hour in "turbo" and up to 30 hours in "low", 2 hours in "max" and about 5 hours in medium brightness. The strobe's frequency is good enough to disorient people. The P2d can stand on its tail and be used for room illumination.
We really liked the UI of the P2D, you have a quick way to get Maximum or Minimum brightness and from Max you are only one click away from the strobe, this has been simple to use in our tests and very flexible for an EDC light. The only detail is that most of the P2D units we know have a beam with a distinctive greenish tint and artifacts due to the LED being offcentered, so if you like a smoth beam of pure white light the P2D may not be your best friend.
