Q&A 

Q1. Can I have a sample order for led light?

A: Yes, we welcome sample order to test and check quality. Mixed samples are acceptable.

However, if the sample quantity is large, the buyers need to pay for the shipping cost.

 

Q2. What about the lead time?

A:Sample needs 5-15 days, mass production time needs 1-3 weeks for order quantity more than 

 

Q3. How do you ship the goods and how long does it take to arrive?

A: We usually ship by DHL, UPS, FedEx or TNT if your quantity is not so small. It usually takes 7-10 days to arrive. Airline and sea shipping also optional if you palce a large quantity.

 

Q4. How to proceed an order for led light?

A: Firstly let us know your requirements or application.
Secondly We quote according to your requirements or our suggestions.
Thirdly customer confirms the samples and places deposit for formal order.
Fourthly We arrange the production.

 

Q5. Is it OK to print my logo on led light product?

A: Yes. Please inform us formally before our production and confirm the design firstly based on our sample.


Q6: Do you offer guarantee for the products?

A: Yes, we offer 1-3 years warranty to our products.

 

Q7: How to deal with the faulty? 

A: Firstly, Our products are produced in strict quality control system and the defective rate will be less than 0.2%.
Secondly, during the guarantee period, we will send new lights with new order for small quantity. For 
defective batch products, we will repair them and resend them to you or we can discuss the solution including re-call according to real situation.

Q:What does the LED bulb patch mean?
According to different applications, different size, cooling scheme and luminous effect of.LED packaging forms. At present, according to the classification of LED package are mainly Lamp-LED, TOP-LED, Side-LED, SMD-LED, High-Power-LED, Flip Chip-LED Lamp-LED (vertical LED) emerged in the early Lamp-LED is in line LED, it adopts the form of sealing packaging. The potting process is the first injection of liquid epoxy resin in LED molding cavity, and then insert the pressure LED bracket welding, in the oven make epoxy resin after curing, the LED from the cavity from the molding. Due to the relatively simple fabrication process, low cost, have a higher market share. (SMD-LED surface mount LED) patch LED is pasted on the surface of a wiring board, suitable for SMT processing, can be reflow, a good solution to the brightness, perspective, smoothness, consistency, reliability and other issues, the The lighter PCB plate and a reflecting layer material, improved to remove the carbon steel pin dip LED heavier, the display of epoxy resin less reflective layer needs to fill, to reduce the size, reduce the weight. In this way, the surface mount LED can easily reduce the weight of the final product in half, make the application more perfect.
Q:LED bulb after the power failure, still glimmer, can last hours or even all day, what is the reason?!
The meter usually doesn't turn because the current is too small to drive the meter (Mechanical), of course, the electronic meter also depends on the sensitivity. I don't think so. At least I used to do LED (light power about 0.5W it) is equivalent to 3W incandescent lamp brightness around. The meter does not rotate when it is shining normally.
Q:Why can't the voice switch control the time of the LED bulb?
The power of LED bulb is much less than that of incandescent lamp, and the control loop and light bulb of simple sound control lamp are connected in series, and the load is different and the time delay is different
Q:The difference between an incandescent lamp, an energy-saving lamp, and an energy-saving LED bulb
The light effects of the three are different. Incandescent light minimum generally below 20Lm/W, the energy-saving efficiency of light in the 60-70Lm/W, the LED ball screw energy-saving lamp in the global market, the quality of the naked light in 100Lm/W, with the outside door cover will drop more than 10%.
Q:How to identify Ic constant current LED bulb?
Another is to destroy the bulb and see the power inside the bulb. Not a constant current power supply, only some capacitors, diodes, resistors, and the like. The constant current drive, in addition to the diode electrolytic capacitor, there is a 6 foot IC and a triode, there is a high frequency isolation transformer. To make it clear, you can take a look at it.
Q:Ordinary lamp LED bulb can?
No problem, the heating LED bulb is mainly aluminum shell above on the lamp body, a lamp holder will not affect the interface, and the heating temperature does not exceed 60 degrees, and the plastic cap interface at least 160 degrees above the melting point, so is not affected on the lamp interface, you can rest assured that use
Q:LED what does "A60" mean by bulb 60? And what does "MR16" mean?
The diameter is 60mm, but the total length of each company is not the same
Q:What are the types of LED bulb?
The LED bulb replacement use convenient, makes this type of products are widely accepted by users by the family, under the same illumination conditions choice to replace the traditional lighting.
Q:In a bulb, the ambient temperature of the LED is LED, the temperature of the air in the bulb, or the temperature of the aluminum substrate
LED working environment temperature refers to the temperature of the air in the LED bulb, not the temperature of the aluminum substrate. The temperature of the aluminum substrate will rise as the LED lights up, and rise to a certain extent, which will involve the highest environmental temperature.
Q:How does the LED bulb look good or bad?
See brightness, whether the luminous uniformity, the back of the heat is good?
