How long can a 18650 lithium battery with Q5 lamp beads last?

The Q5 lamp bead is 5 watts. How long it continues to discharge depends on two factors: the first is the designed discharge current of the flashlight driver board and the second is the battery capacity of the 18650. If the discharge current is 800mA per hour and the battery capacity is 1600mA, it can be used for more than 2 hours with continuous discharge. The discharge current of a flashlight is generally the maximum current in strong light mode. If low light mode is used, the continuous discharge time will more than double. For example, strong light discharge for 2 hours, weak light can be used for more than 4 hours.
