Q:Which is brighter, the xenon lamp or the LED lamp in the torch?

However, from the original considerations, LED lights are the first choice, power consumption is relatively lowXenon flashlight to use lithium battery, xenon lamp generally about two lithium battery lasts for 60 minutesThe battery cost is relatively high, a section of the cheapest also need 5 pieces. Every minute in the burn.

Q:The hernia lamp and the Led light flashlight are good

Auto light is hernia, definitely longer than LED life, brightness

Q:LED flashlight instead of direct plug in power lighting

You'll have to get a transformer to change the AC to dc.

Q:What's the brightness of the LED flashlight?

You can see now Shenhuo, better understand the customer, Feinikesi, wolf, these brands you can refer to the.

Q:What are the parts of a LED flashlight?

1. LED led for lighting

Q:Why is the bulb of the LED flashlight only two bright?

LED is a light emitting diode as the working voltage of general flashlight LED is about 2~3V, the working current of about 20mA, the maximum voltage flashlight can provide only about 12V, so LED is two a series with a current limiting resistor. Only two of them are still bright. It is possible that the rest of the LED is broken down or the resistance is aging. The resistance increases and the rest of the LED is not bright.

Q:How to detect the flashlight LED lamp is good or bad?

It may be because the measurements in the plate, 6 beads in parallel, and the meter provide insufficient measurements of current shunting. Well, after the 2 1.5V batteries are connected in series, measure directly, or measure the resistance of the mobile phone battery string 50, or measure the resistance of the charger with a 100 ohm charger.As long as the measurement voltage is controlled at about 3V DC or the current under DC 20mA is measured, the results can be obtained directly in the plate measurementPut aside

Q:Flashlight, bright lights, led charging, which is good?

The flashlight Market is deep water, if asked for it best according to their own requirements to buy parts together, if it is bought just buy a regular domestic factory in line with the use of words, the mountain "Shenhuo" it is best not to use.

Q:Strong flashlight, what model is the brightest, LED?

SM-7045 brightest bright flashlight, super bright inspection flashlight,Light emitting diodes, referred to as LED. Made from compounds containing gallium (Ga), arsenic (As), phosphorus (P), nitrogen (N) and so on.

Q:Usually Led flashlight lights specifications and price.

The high-power LED flashlight, with imported CREE LED more. Of course, CREE LED is also divided into dozens of different types and colors, the price is not the same, from a few dollars to tens of dollars.
