Will they work? Yes, but......... you will not have the lower modes. All the modes will be the high brightness level.
Unless you use a lower voltage RCR123.

Tricker, I highly recommend the LiFePo4 http://www.cpfmarketplace.com/mp/showthread.php?t=125353
Pros:
(1) Safe Chemistry - will not potentially vent/explode like the other Li-ion types.
(2) 3.2V - so you get to use all the different modes (high/turbo/low/stobe/SOS).
Cons:
(1) Not protected - you must be careful not to over discharge it. If you do, it's not going to vent/explode like the other standard Li-ions potentially do when deeply discharged, but you run the risk of damaging the cell.
NOTE on runtime of LiFePo4: Others on this forum seem to think the run-time is an issue. That really depends on your usage. With a rated capacity of 500mah, your P1D will run for close to 1 hour on primary mode (96 lumens) drawing about 350ma initially (check the link above and someone actually tested the runtime and had some graphs, etc). I use my PID Q5 as a EDC, with an average usage of 10 minutes a day, so every few days, I simply swap batteries and recharge; I don't wait till it runs low. If I need extended runtime, I simply carry spares in my car or bag, etc.
NOTE on standard protected Li-ion: Others may recommend standard Protected Li-ions running at 3.0V or 3.7V. Personally, I am not comfortable with the chemistry because these kind of Li-ions depend totally on a piece of electronic circuit board to keep it "safe". The protection circuit when working will keep the those Li-ions safe. However, should the protection circuit fail, then you run the risk of deeply discharging the cell and that could potentially cause venting. The P1D has a pretty airtight body, so if those li-ions vent, you have the potential of a mini bomb going up in your pants!

is more mAh better......"6 RCR123A 3.0V 750mAh LiFePO4 Rechargeable Batteries with a Smart Charger" for 27 dollars is a pretty good deal and will work right, since rated battery output is above fenix intake?

Hmmm... I found these:

Doubts about chinese goods not withstanding, does this mean that I can use these 3v rechargeables in the PxD series with abandon? I have avoided these lines because I am allergic to the $$$ of CR123 batts.
