FAQ

1-May I have your samples for existing items?
According to our sample policy, samples are free of charge for our common existing ones within a certain amount but customers need to bear the express charge. If customers have an international express 
collect account no. for FedEx, UPS, DHL and so on, this will be more convenient for us.For long-term business, we could bear the express charge.If customers are satisfied with the finished samples and will

settle the first order, we will start to refund the sampling charge. For actual refundable procedure, this will be finalized according to actual sampling charge, the first order amount and actual communications.

 

2-Could you do sampling according to my actual sample, special demand, design or own idea?
Our R & D dept. has experienced engineers in structure and electrocircuit. And we have good cooperative factories in molds for plastic and metal. Based on these, we are able to achieve your demanded samples.

 

3-How do you control the quality?
We have strict quality control system including incoming material inspection, production line management, final full inspection and random inspection on loading. Based on these, we are able to deliver final high quality products for you.

 

4-What's the period of validity for complaint?
Normally, we accept the complaint within one month after receipt of the goods. For some special circumstances, please kindly contact with our sales for your actual order.

Q:Is led flashlight used widely?
You can see the domestic, there are now many manufacturers like wolf, Tongming, Solomon, love to laugh and all that can be seen under the sand is not very expensive, you look at the specific kind of feel good
Q:LED lights of the mobile phone as a flashlight, open for a long time will be bad
Not too long, long time will be hot, it is only emergency use only
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.
Q:Please master to help me identify what LED said, the more detailed the better, Pailide GL-K139q flashlight inside, not CREE.
Domestic Taiwan led also understand some, fever is less current is too small, can not withstand high current, small current, of course, power consumption will be small, the same current, CREE led heating is not greater than them, brightness is not lower than them
Q:What compulsory certification does it require to import LED flashlights in Europe?
RoHS is an directive of the European Union. If the products are exported to the EU or Japan, they should comply with ROHS, otherwise they will be fined and criminal penalties will be imposed. So, if you want to export, be prepared. To avoid unnecessary losses. Many manufacturers have abandoned the EU market because they are not in line with rohs.
Q:How long has the LED flashlight battery been repaired?
First, disassemble parts: the tail switch is difficult to disassemble, and basically eliminates the possibility of the problem; the lamp cap is completely disassembled (including bulb, circuit board, aluminum ring), battery pack.
Q:Why should a bright flashlight use a 3.7V battery, and why not?
High voltage lithium battery, the working voltage of 3.7V, and the driving voltage of LED is about 3.3V, and the driven part of the pressure drop, a lithium battery just right. If the dry battery, NiMH, requires 3 day series, if you want a single 1.5V driver LED to boost driver, boost large current driving cost is high, and the copycat flashlight, in order to reduce costs, with the current limiting resistor in series, the voltage of the battery must be higher than the working voltage of LED.The rest is the inherent characteristics of lithium battery, high energy, light weight a lot.
Q:LED LENSER flashlight, okay?
Advantage1, led long service life, generally can reach more than 5~10 hours, compared to the traditional tungsten filament lamp life 5~10 times higher.2, cold light, low heat, will not damage the lamp holder, high safety.3, fast reaction, collision resistance, good weather resistance, small size, easy to small, lightweight.4, power saving, energy saving, low power consumption, green environmental protection material.5, the speed is fast, as long as 1US (microsecond), do not have to warm the lamp can improve safety.6 、 low voltage drive (voltage is 1.8~4.0V) safe.
Q:Rechargeable LED flashlight
Pay attention to whether the resistance power is enough, although the current is very small, but the resistance to share the voltage will be great, so power enough
Q:Can LED light beads be replaced by ordinary flashlights?
You need to find a diode with a pressure drop, or it will burn the diode if the light is not bright or too bright.LED luminescence principle:The terminal voltage of PN junction constitutes a certain barrier. When the forward bias voltage is applied, the potential barrier decreases, and the majority carrier in the P region and the N region diffuse to each other. Since the electron mobility is much larger than the hole mobility, a large amount of electrons will diffuse into the P region, which will result in the injection of minority carriers into the P region. These electrons are combined with holes in the valence band, and the energy is released in the form of light energy when combined. This is the principle of PN junction luminescence.
