AA or 14500
The Fenix LD09 flashlight features the intelligent drive circuit which allows you to use either a 14500 rechargeable Li-ion battery or a standard AA. The LD09 has three brightness levels with a maximum 220 lumens and 433ft beam distance. The tactical switch allows for fast and easy operation of all modes including S.O.S. Compact and durable, the Fenix LD09 LED flashlight is a perfect every day carry flashlight that easily meets your daily lighting needs.
Great to have in different places around the house.
Really nice light and great power levels. The beam spread pattern is similar to the pd35v2. I think that is excellent.
Additionally, to add a battery only the front portion of the light unscrews instead of both the rear and front unscrewing. I think this was an excellent engineering decision.
I just wish the tail switch could be momentairly pressed to change the light levels after the constant on press - like the LD02 and my old LD22.
It seems like you can only click the light momentarily to change light levels before the constant on. Meanwhile other lights allow the action either before or after the audible click for constant on.
Surprised that a tiny light can shine bright, and it is built on quality...Very pleased of the product.
