This lamp can be used as a lighting tool when outdoor activities at night. Can also be used for lighting when making videos or photos, because the light is bright and spreads in all directions. The light produced by this flashlight is very smooth, there are no lines or light centered at a certain point.
Battery life on this flashlight is only about 3.5 hours. Because I made this flashlight for the purpose of taking videos at night with a duration of about 2 hours and requires a bright light intensity. The solution, in order to last longer you can reduce the number of HPL LED lights with the consequence of reduced light intensity. Maybe reducing the number of HPL LEDs can reduce the amount of power consumption in the battery. So the lights can last longer about 12 hours.
