The StreamLight ProTac 2AA is a medium-sized, tactical flashlight that generates a 250 lumen beam and uses standard AA batteries. The 2AA is about the size of a very large marking pen and could easily be carried in a pocket or holster. It uses the standard Streamlight programming with High/Strobe/Low and also offers the TEN Tap programming to switch it to High/Low only or Low/High only. This flashlight is a good choice if you want a light that is easy to carry that also uses standard AA batteries.

Features include:

• Beam: 250 lumens at 4,250 candela with 130m beam
• Runtime: 2 hours from two AA batteries
• Holster: Tear-resistant nylon holster included
• Construction: Anodized aircraft aluminum with polycarbonate lens
• Durability: IPX7 waterproof at 1 meter for a minimum of 30 minutes
• Size/Weight: 6.14″ long and 3.4 oz w/batteries
• Beam Pattern: 41″ x 8″ at 3′ (Beam Scale)
• Colors: Black
• Cost: About $40

It is a basic, tactical flashlight that is easy to carry. It uses two AA batteries, has high/strobe/low modes, and the body is machined from aircraft aluminum. The 2AA is on a low size of the tactical scale. While 250 lumens is bright I would prefer more lumens and higher candela power for a tactical flashlight.

Recommendation

Always consider batteries when building your emergency kits. There are better tactical lights but most use CR123 batteries. CR123s cannot be charged but it is easy to find rechargeable AA and AAA batteries. There are rechargeable 123 batteries but you must be very careful when using these because they output a higher voltage than standard CR123s and they could damage your flashlight. Solar charges such as the Goal Zero Nomad can charge AA and AAA batteries. If you need to charge batteries in the field then you may want to standardize on AA and AAA batteries. If you find the need for an AA powered flashlight then the Streamlight ProTac 2AA is a very good choice. Also, if your headlamp uses AA batteries then the ProTac 2AA would make an excellent backup light.
