AAA7 XP-E R2 120-Lumen LED Flashlight with Strap (1*AAA/1*10440)

Pros: - small - metal, knurled body - gaskets at joints - 1 mode of light - clicky switch - quite warm light (yellowish) - strong light

Cons: - joint between head and body not well coapted and gasket is pushed out of its groove during screwing together, while gasket between body and tailswitch hides completely inside.

Other: Buy if you need small and strong light source.

Pros: 1) Bright with a 3.7V battery. 2) Compact 3) Ease of operation 4) Sufficient light for Bicycle. 5) Very bright w/ 3.7v battery

Cons: 1) LED Driver rattles inside. Tightening it down makes for a loose contact with battery (thus, the 4 star vs 5 star rating on quality) 2) Needs a Pocket Clip. 3) Excellent for the price.

Other: Take into account that 3.7V 10440 rechargeable batteries have a low mAh (500) and will not hold a charge for very long. But, for the size [and when the solutions above are applied] makes for an all around 5 star rating and excellent bright light when needed for most emergencies.

Pros: 1) Bright w/ 3.7V battery 2) Ease of use (1 hand operation) 3) Compact 4) Sufficient light for use on a bicycle

Cons: 1) LED Driver rattles inside head of device 2) Needs a Pocket Clip

Other: There are other Torches/Lights available that are shorter and narrower, but they cost more and have Rotary ["Twisty"] switches. This one is a "Clicky" at the rear and good for [1] hand operation
