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: 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 bulb with what type of LED beads?: The LED bulb is mainly white and warm white two colors are white, the temperature is generally 6000-6500K color, the color of the sun light at noonWarm white temperature is 2700-3000K, yellow, similar to the sunset color temperature.

Q: Why is 3W's LED plastic bulb so cheap on the market? Is there any drawback to the price difference between aluminum and aluminum?: The difference of power factor is large, and the resistance capacitance pressure drop is below 0.5 PF. Constant current and constant voltage drive PF over 0.9. The resistance drop pressure is really attractive, after all, the price is there. The average person doesn't understand the look.

Q: LED bulb w can replace 40W incandescent lamp: I am engaged in the LED drive industry, not very professional, and I hope to help you.About brightness and energy saving comparison,1W LED=3W CFL (energy saving lamp) =15W incandescent lamp3W LED=8W CFL (energy saving lamp) =25W incandescent lamp4W LED=11W CFL (energy saving lamp) =40W incandescent lamp8W LED=15W CFL (energy saving lamp) =75W incandescent lamp12W LED=20W CFL (energy saving lamp) =100W incandescent lampBecause the company uses the light quality is not a reason, so this is not absolute.

Q: What's the reason for the LED bulb strobe?: If this resonant characteristic causes the input current to fall below the TRIAC sustaining current, the TRIAC will turn off. After a short delay, the TRIAC usually switches on and fires the same resonance. In the 1.5 cycle of the input power waveform, this series of events may be repeated several times to form visible LED flashes. To cope with this problem, a key requirement of TRIAC dimming is that the input capacitance of the EMI filter is very low and that the capacitor is decoupled through the TRIAC and the winding impedance. According to the formula, if the capacitance of the dimming module is reduced, the resistance of the resonant circuit can be increased, and the oscillation is suppressed in principle, and the desired circuit work is resumed.

Q: What are the characteristics of LED bulb?: Life is more than ten times longer than incandescent, power consumption is 1/2 of ordinary light bulbs, fast response, generally 10-7 - 10-9s, color clear, recognizable performance, good vibration resistance, now the price of LED lamp is relatively high

Q: LED bulb after the power failure, still glimmer, can last hours or even all day, what is the reason?!: If it is to continue the glimmer of minutes, the main side is the use of resistance and step-down circuit caused by the normal phenomenon. It's very rare for the factory to use this old model to make LED balls. Circuits that run for hours or all day on the side of the LED bubble are out of order. It's not normal to shine for so long. Now most of the LED bulb is using IC constant current supply circuit, no such situation has emerged.

Q: LED what does "A60" mean by bulb 60? And what does "MR16" mean?: 60: diameter 60mm (metric unit) MR16: diameter is 16*1/8*25.4mm (Imperial units), although refers to the diameter, but the height and other dimensions are also prescribed

Q: LED bulb is broken. The luminous patch is not bad. Can it be made into USB lamp?: Look at the LED in the LED bulb. Several LED are connected in series. Several groups are connected together, and then the voltage is estimated. Then the power of the bulb is divided by the voltage of the LED bulb to calculate the required current. Select the appropriate LED drive circuit. The average USB output current of the computer is only 100mA~500mA. The power is not enough to make the LED light achieve normal brightness, or it may damage the USB interface. It's better to use the USB charger interface. DIY needs circuit knowledge.
