Quality Level, no problem: it's solid apparently!
As said in other reviews, it can be used truncheons and more!
Technical information that can be used for future buyers:
This lamp allows use with several battery models and with 2 or 3 batteries.
The use 3 batteries increases the brightness compared to 2 batteries.
Increasing the battery capacity increases the autonomy and not the brightness.
For example, use 3 26650 3000mAh battery, you will have the same brightness by using 3 26650 6000mAh battery.
By cons, with 6000mAh, you will (in theory!) 2 times more autonomy than with 3000mAh!
Besides, on the same principle, you will also have the same brightness with 3 batteries 18650 26650 Battery with 3 ... (the same voltage, the only difference is the capacity)
To conclude, I am still satisfied with this lamp!
