The Lumintop BLF GT90 flashlight is powered by 8 x 18650 Li-Ion batteries. The battery indicator helps users check the battery status. It also estimates how much runtime they have left before recharging the battery. The BLF GT90 cannot charge batteries. You may need an external charger to keep your battery going. The flashlight detects when the battery's voltage has dropped to a certain level. Then, it reduces or cuts off the power.
The built-in thermal control adjusts brightness output to prevent overheating. The "6" in the IP65 rating shows the level of protection. It's against solid objects, like dust and foreign particles. The IP65 rating indicates that the flashlight has a protection against water jets.
According to the ANSI/NEMA FL1 Standard, we measure the performance of the BLF GT90 flashlight 30 seconds after switching on the light. The ANSI/NEMA FL1 2009 Standard is a set of flashlight performance guidelines.
