Fenix P2D/L1D combo

[Niconical]

Need some advice please

This is a Fenix P2D/L1D 4-in-1 pack that many of you are probably aware of.

This is just a L1D body.

I already have a P2D Q5. (Which BTW I think is totally stunning, I'm still in the flashlight honeymoon period, I hope it lasts forever). Does that mean I can just buy the L1D body, add to it the head and tail from my P2D Q5, and then have a 1 x AA PL2/1D or whatever it would be called?

Sorry if it seems obvious but I'd not sure if maybe the items in that pack are different, and I don't want to do an international order for something that if I'm wrong will just be a very expensive bit of aluminium tube with "L1D" written on it.

Finally, if it does work, does that also mean I can do exactly the same thing but with this L2D body?

Thank you

good question! im interested in the answer to this too!

Yes, that is correct.

The P2D, L1D, and L2D all share the same head.

This is the L1D's body for sale at Fenix-store. It indicates that the body is compatible with: L1D CE, L2D CE and P2D heads

This is the L2D's body for sale at Fenix-store.

Enjoy your light.

yes if you have P2D all you need is the L1D body AND tailcap , same for L2d

P2D whole
L1D Body&tailcap
L2D Body , tailcap not necessary if you have one for L1d ...but i would still get one anyway so that i dont have to unscrew head and tail for every switch , just the head

Careful of the body only offered at Lighthound, you will need the tailcap also when going between CR123 and AA. The heads are the same, but the tailcap inside diameters are just slightly different. The Fenix Store link above is for the body with tailcap, and is what you need.

EDIT: qip types faster than me!

Thanks for all that :thanks:

When I first saw the picture of the 4-in-1 pack it looked like it included just a spare body, but now I have read what you both put above, if I look closely I can see that the spare body also has a second tailcap with it.

I haven't ordered from Fenix-store yet, but they seem very popular, so maybe these items will be my first from them.

I do have some more doubts about the batteries, but rather than just ask yet more questions, I'll try to answer them myself, then maybe someone can tell me if I'm right......, or wrong.

This is how I see it.

"I should use good quality AA, Nimh or Lithium if possible, but alkalines will work. Assuming Nimh/Lithium, even from 1 x AA I should get more runtime as the cell capacity is higher than the CR123A, and certainly a lot more runtime using it with 2 xAA. The brightness and regulated time with 2 X AA should be similar, like the 'real' L2D, to that of the CR123A, 3v or 1.5v x 2, same thing, but if using it with 1 x AA like the 'real' L1D, the overall brightness and regulated time will be lower."

There, have I managed to answer my "question"? I hope I have as I'll finally be answering questions instead of asking them. OK, so it was my own question anyway, but it's a start! :twothumbs

That's pretty good. Self-answered question.

Here's some additional information:

CR123a has higher voltage (3.0v) and more efficient than 1 x AA (1.2, 1.5, 1.7v, for NiMh, Akaline, and Lithium, respectively) so it'll have slightly higher runtime despite it's lower cell capacity.

Also, although you could use Akalines for the L1D/L2D, Akalines are not good for any device that demands high current (like these lights). Akalines have higher internal resistance, so a lot of the current draws will become wasted heat. I would recommend using low self discharge (LSD) NiMh batteries such as Eneloop. Regular NiMh batteries will discharge itself within a couple of months ... LSD batteries will retain about 85-90% juice for a year (could be longer).

Primary Lithium battery (Energizer L91) is the best, but it's quite expensive and you could only use it once. Rechargable Litium Ions (Li-Ions) are great, but carries 3.7v, which is not compatible with the Fenix L1D/L2D. Well, you could use it with the L1D and it'll be really bright, but you lose all modes except for the turbo and strobe ... and run the risk of blowing the circuits (and void all warranties). Some members do it, some don't.

That's all I could really think of for the time being.

"I should use good quality AA, Nimh or Lithium if possible, but alkalines will work.
