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 aprocedure, 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:Use LED lamp plant useful? Useful for which plants, which plants useless?
In general, grow leaves, red light demand is big, the be fond of of different plants will differ slightly. Do not have the distinction of good or bad, the key see you kind of plants. Blue light, and is good for some plants flowering. It is common used red light blue light match up.
Q:The service life of LED lamps and lanterns is true?
Theory is a 30000 h - 50000 - h (semiconductor diode). 1. The chip encapsulation (not the same environment, affect the life. And the light bulb how to low the situation is not possible, this is a standard) 2. The power drive power supply (electronic products, general is 2 years,) 3. The lamps and lanterns, the whole life is a long time, generally 2 to 3 years.
Q:LED rechargeable lamp, what to do with the battery can't charge.
Suggested to change the battery. LED rechargeable lamp charging circuit is simpler, less damage, the battery is not usually in electricity is pure battery failure. So suggest replace the battery.
Q:The LED rechargeable lamps can charge while lighting? The reason?
Desk lamp is not poor, not because of burn out, because the light and a battery, so the voltage may be no more than the battery voltage
Q:LED lights it is transistor luminescence is not pure resistance filament bulbs, when dimming voltage changing, the frequency is changing so affect rectifier, sudden high voltage will burn out the LED.
LED lights, sort is more, the most common of which are blue chip and yellow phosphor, this kind of light blue light is too much, cannot be used for reading. Advanced LED lights (red, green and blue), color rendering index are also more than 80, of around 4000 k. However, it is expensive.
Q:The LED lamp is bad for your eyesight?
I don't know how you this table lamp LED performance, but the average white LED light slants cold, as compared to that of the object under the LE in natural light color nature is soft, so as a desk lamp may not good for your eyesight. But replace other USES energy-saving lamp is very good at home
Q:The led lamp charging more than 24 hours have what dangerous?????
Nothing dangerous, now of the rechargeable battery charging circuit with protection circuit, with or after high temperature will automatically stop charging
Q:Led desk lamp and common desk lamp which is good
If the wavelength change, stimulate phosphor ability to drop, luminous efficiency will be lower. Manufacturers in order to pursue the brightness, usually to strengthen the blue LED light intensity, the eye if the long run, such a source to avoid eyes blue light damage. In addition, it is, the longer the LED light, the faster the phosphor decay of light source, the result will lead to the human eye contact blue wavelengths of light is more and more intense, so as to cause harm to the human eye
Q:Folding LED touch lamp generally will be problematic
This topic is not answer, because the LED control method are many, and the way of touch also many, control way is very much also, only from the basic principles. Caused by electric current is the main reason for the failure of light, at the same time, the LED lamps and lanterns has typical characteristics of diode (very small voltage variation, huge current change) so, LED lights control method based on current control is the best, since it is control cannot use constant current source, but to use can control constant current source. In controllable constant current source, a switch type and linear type, because the switch type is inductance as the main device, and a sharp tuning switch frequency will cause many problems, it is easy to damage the leds, controllable linear constant current source is low efficiency, but the problem is less easy to implement.
Q:With few desk lamp LED tile good children
Between 5 w - 8 w, no stroboscopic, can choose move light and color temperature of LED desk lamp
