If I were you, I'd get a 2nd gen. (new) CMG Infinity. Try to order some lithium AAs with it as they give twice the life & are brighter. I love my CPF edition Arc-AAA, but AAs are common, the Infinity is cheap and bombproof, and I have had no problems with mine "in the field" in places like Thailand (for example).
Here are the lights I currently have:
SureFire M2 w/ (1) spare carrier, usually a P-61 LA and a FM65 red filter cap + (2) spares carriers
SureFire E2e HA (with a red filter if necessary)
Brinkman Legend LX
Pelican MityLight (2AAA) w/ clear & red lenses & opaque cover
Pelican 2AA angle light (I think the model name is: "lightning bug"…?)
Princeton Tec Tec-40 w/ red (& clear) lenses (Lithium AAs)
Princeton Tec Matrix headlamp (w/ Lithium AAs)
Princeton Tec Predator (camo) headlamp (w/ Lithium AAs, Matrix LED mod, and red lens cover)
Maglite 3D w/ LED conversion
(2) 'normal' Maglite 3Ds
Maglite 2AA (lithium) w/ magnet & clip
Streamlite Polypro 3C Police
Arc-AAA (CPF edition
)
Inova X5 (titanium / white)
CMG (2nd Gen.) Infinity (red LED) w/ Lithium AA)
CMG (2nd Gen.) Infinity (green LED) w/ Lithium AA)
CMG (2nd Gen.) Infinity (white LED) w/ Lithium AA)
Photon II (red)
Photon II (white)
Photon II (turquoise)
Candle lantern (w/ LED base
)
Eveready 3AAA "el cheapo"
