Fenix AAA lights:
E0 is a 5mm LED light. 4 lumens for 5 hours. EDIT correction 9+ hours.

E1 is a "1/2 watt" light. 11 lumens for 1 hr 40 mins.

L0P is Fenix's 1st Luxeon AAA light. 30 lumens for 15 min (alkaline) 50 min (freshly charged NiMH)

L0P SE (P=premium, SE=special edition) is a 3 mode light.
Medium is 11 lumens for 1 hr 40 mins. Similar to an E1.
Low is 4 lumens for 5 hours. Similar to an E0.
High is 30 lumens for 15 min (alkaline) 50 min (freshly charged NiMH). Similar to an L0P.
So you get 3 lights in 1.

L0D (D=digital) is an L0P SE with the addition of strobe and SOS modes.
Strobe is useful for making people aware you are there. Such as crossing the stret at night.
SOS (..._ _ _...) is great for shining at Al Gore during the Save The Planet Concert.
There are Holiday versions of the L0D in red and green with snowflakes.
L0D CE (CE=Cree edition) is an L0D with a Cree emitter.
Medium is 15 lumens for 1 hr 40 mins.
Low is 7 lumens for 5 hours.
High is 45 lumens for 15 min (alkaline) 50 min (freshly charged NiMH).
The increase in brightness is most noticeable in the spill light, allowing you to see a wide area clearly.

L0D RB80 (RB=Rebel LED, 80= 80 lumens at 350 mA) is a L0D with a Rebel emitter.
The RB80 has a stronger hotspot but weaker spill light than the L0D CE. For throw (distance) the RB80 is better. For closer work the CE is better.
Some people like the warmer (less blue) tint of the RB80.
The LATEST THING is Fenix Limited edition L0D Q4 in Dark Red (Hard Coat)!
This puppy tops out at 75 lumens with a single AAA!
It comes in a beautiful matching red box.
-----
Fenix name convention:
L series Lights that use common batteries
P series Powerful lights that use 3V CR123A batteries
E series Economical lights
T series Tactical lights coming soon.
The CR123A (123A=one 2/3 A size) are shorter but fatter battery than AAA. So a 1xCR123A light such as P1 CE is shorter but fatter. Because the batteries are double the voltage of the AAA the lights are also much brighter. Problem is they are usually expensive locally. Care should also be taken when using them. Most the exploding flashlights mentioned on CPF seem to be using 123A batteries (usually multiple 123A)

BTW it is L-zero-D. Not L-oh-D.
