What is the driving current and voltage of LED? How much current and voltage do I buy for 50W? Safety flashlight?
Generally according to personal habits and professional level, outdoor diving will also be equipped with at least 3 flashlights.
The 18650 lithium battery is the only power source. The LED flashlight will run at 95% full brightness for 6 to 8 hours. Strong light flashlight energy-saving energy without pollution is environmental protection. DC drive, ultra-low power consumption (single tube 0.03-0.06 watt electro-optical power conversion is close to 100%, the same lighting effect is more than 80% energy saving than traditional light sources.
Designer Daniel Barnes and his team Beryl designed a safest bike light-Laserlight Core.
Please fully charge the lamp when using it for the first time, and charge it in time after each use. Atomic electrons in led flashlights have many energy levels. When electrons transition from a high energy level to a low energy level, the energy of the electrons is reduced, and the reduced energy is converted into photons and emitted. A large number of these photons are lasers.
The following is about The history of the development of flashlights.
