Q:How long can a LED rechargeable flashlight last?
It depends on how many flashlights you bought! The full charge of the three bulbs can be used continuously for more than 8 hours! The continuous use of four bulbs in about 6 hours! Of course, if it's a big flashlight, it's different. What I'm talking about is an ordinary flashlight (about 20 centimeters long).
Q:Led bright flashlight, is it easy to use? Is it Expensive?
I am doing titanium lighting flashlight, the flashlight irradiation effect is relatively strong, mainly C10 flashlight with 800 lumens single chip CREE XML T6 LED, close the pan light intensity, long distance focusing, pavement irradiation effect is great, and the first choice is the outdoor riding at night. 18650 hours straight, with another T6 LED small size, brightness super awesome, you can exchange.
Q:At present, the LED flashlight commonly used in the market, the built-in lead-acid battery is too bad, can use 4 nickel hydrogen rechargeable battery instead?
Its battery life is short, mainly due to charging circuit caused. At the same time, the lamp component is current limiting resistors, greatly influenced by voltage. The current limiting resistor is selected according to the 4V voltage. When the voltage becomes higher, lamp current will increase obviously. When used instead of 4 Ni MH battery when the battery voltage is 4.8V, current lamp is much greater than 4V, so the lamp of life is very short. At the same time, because the charging circuit design is very unreasonable, the battery life is also very short.
Q:LED flashlight batteries instead of cell phone batteries
Agree with the upstairs view, LED flashlight battery voltage between 3.7-4.2
Q:Please master to help me identify what LED said, the more detailed the better, Pailide GL-K139q flashlight inside, not CREE.
The biggest advantage of domestic LED is cheap, city led is used to consider the cost, with many things must choose the cheapest price, I mean the flashlight used in LED is not used or decorative landscape lighting is led Oh, that few CREE, nobody knows that do not understand, does not mean that he is not good, not every field by the public know excellent brand too much, not public necessities flashlight is at most a fancier play, can say is a toy, so the number must belong to a small thing, than the number or the property of the country led up, if the price is CREE and domestic flat, so that the rate of CREE use more domestic than to be sure, of course to exclude domestic manufacturers through bribery of government departments or unfair competition order
Q:10W's LED bright flashlight is on all the time. How much is the power per hour?
Battery voltage 12V, 10W is 833mA, power consumption 833mAh per hour.
Q:Paili de LED flashlight in "180 lumens," what do you mean?
1 lumens refers to a size of 1 cubic meters of the cube, the brightness of a candle lit, 180 lumens as is in a 1 cubic meters of space, the brightness with 180 candles lit.
Q:How to change a third LED flashlight
According to your LED current, buy a suitable current driver board, you can have that kind of general drive, the formulation of current, 350-1000 can be changed!
Q:What are the models of ultra high brightness LED on flashlights?
Other LED, such as quad core P7, LED, SSC produced, 900 lumens, in the flashlight on the application of quite a lot, there are some other LED, not one by one to repeat it.
Q:LED flashlight MH7303 how to achieve explosive flash function, there are circuits as follows, but that is, can not achieve detonation flash!
Schematics are wrong, the principle is not through, you MH7303 output control of the wrong place, so it can not be controlled! MH8910 wiring is also wrong!
