Product Description
Specification:
Quality Control
1. 100% of the lamps will be tested and keep lighting for 24 hours to test its quality reliability
2. we will also test its temperature after 24 hours lighting
3. after it is cool we again test 100% of the lamps to see if it still work well
4. all lamp should pass all these QC procedures before the packing.
Features
1) We use high quality SMD LED as light source, which is high brightness, long life and less heat

- Q:60W how many lumens and how many W LED bulb does incandescent bulb replace?
- A LED lamp lumens general good point value is above 100;The brightness of 60W incandescent lamp compares with LED lamp difference is 10 times;
- Q:Want to find common features, unified purchase accessories repair!
- The proposed open, lamp is broken, can find light black or other unusual circumstances, bad power supply at the circuit board and components have the same burn what, under normal circumstances is such.
- Q:LED can the bulb be used in the bathroom?
- of couse Yes, but LED kitchen and toilet light is recommended
- Q:What's the reason for the LED bulb strobe?
- In addition, electromagnetic interference (EMI) filters are also required, even in LED drive applications that provide excellent power factor correction and support TRIAC dimming. The transient current caused by the TRIAC step (step) will excite the natural resonance of the inductance and capacitance in the EMI filter.
- Q:What material is applied to the glass cover of the LED bulb? Can reach 90% of the light, can not see the inside of the lamp. Who knows, thanks for telling!
- Sandblasting can be transparent, light is not dazzling,But will still see the light...
- Q:Will the power of the LED bulb grow longer and longer? Why?
- Voltage problems, as well as unstable factors.Long time no change, should
- Q:Why can't the voice switch control the time of the LED bulb?
- Current problem. The current is too weak. You don't have to use an electric meter to see if you can work properly without a light bulb. Change the timer switch.
- Q:Can the bulb's true life reach 30000~50000 by LED?
- The theory of the life of LED is one hundred thousand hours, this is not true; but the LED life is far less than one hundred thousand hours, only ten thousand hours, which is currently the most industrialized production of long life; because the quality of the LED part of the core - epitaxial wafer has not reached the ideal state, there are many problems to be solved, such as reducing the dislocation the density of epitaxial film, high quality P GaN preparation etc.
- Q:Will the LED bulb, T8, T5 lights, radiator lamps, is the hotter the better? What's the regular temperature? What are the common heat release materials? Specifications?
- Of course, the hotter the better, because for the same material, the hotter it is, the more heat the LED chips use, the less good the quality of the chips. The thermal characteristics of lamps is mainly to measure the junction temperature of LED Shenglai rather than the temperature of heat sink. Aluminum is commonly used in heat dissipation materials.
- Q:LED what is the glue between the aluminum base of the bulb and the cooling aluminum?
- It is best not to direct contact with glue, glue because the thermal conductivity of aluminum than a lot of difference, even a thin layer will reduce the heat out of the speed of the screw can be used to aluminum plate and aluminum fastening together, the contact surface is smooth, when necessary, can use some conductive silicone grease amount
