- Q:LED flashlight batteries instead of cell phone batteries
- Agree with the upstairs view, LED flashlight battery voltage between 3.7-4.2
- Q:What kind of batteries do LED flashlights usually use?
- Flashlight flashlight is generally used in lithium batteries and dry batteries, and now we use the lithium battery flashlight more, because lithium batteries can charge, more convenient point, will not pollute the environment, more environmentally friendly.
- Q:What's the flashlight industry standard?
- At present, the national organization for Standardization (ANSI) and the National Electrical Manufacturers Association (NEMA), the United States, the United States flashlight flashlight Standards Board Standards Committee and consumer representatives ANSI/NEMA the latest international standard FL1-2009 flashlight measurement standard jointly developed has been promulgated and implemented, the standard provides the direction of lighting the basic characteristics such as portable, portable flashlight, spotlights and headlights, flashlight is the measurement requirements of the international standard written.

- If simple, buy a 1W or 3W lamp, a series resistor and slightly on the battery is good, the cement resistance of 12 ohms around 0.25W, 3 batteries of about 4.5V, the general lamp voltage of about 3.3V, can not be added directly on the battery. Standard can be two batteries plus step-up circuit approach, but you do simple, there is no need to be so troublesome.
- Q:Would you please use the LED of a flashlight with size 5 batteries to make it glow with a No. 3 or 7 ordinary battery?
