Q: LED what is the plastic shell of the bulb? What plastic material is better? What do you need to pay attention to?: You should say that the bulb of the bulb, usually PC material.

Q: LED bulb PC, will the white cover affect the color temperature of the finished lamp?: I've got my lighting engineer to give you a professional answerBecause the light barrier is selective for light waves, that is to say, the transmittance of light at different wavelengths is inconsistent. When the lamp cover is covered, the luminous spectrum of the light source is changed because of the filtering of the lampshade, and the color temperature certainly has certain change.Professional lampshade company should have the detection of the passing rate of different wavelengths. Is your lampshade provided by professional lampshade company?

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

Q: Ordinary lamp LED bulb can?: Absolutely, without any effect. It can be directly across to look at the opening of several inches.

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: LED can the bulb be used in the bathroom?: Yes, the bulb may is waterproof and dustproof with protection

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: Will the power of the LED bulb grow longer and longer? Why?: The LED bulb does not become more powerful for extended periods of time.

Q: Detailed description of LED bulb lamp: Healthy LED is a green light source. The LED lamp is driven by DC without flicker. Without infrared and ultraviolet components, without radiation pollution, it has high color rendering and has a strong luminous directionality, good dimming performance and no visual error when the color temperature changes

Q: What does "A19" mean in LED A19 bulb?: A stands for bubble type, A hemisphere bubble19 the numbers in the back indicate the size of the bulb (mm in diameter)On the market LED bulb generally has: hemisphere bubble lamp, A15, A17, A50, A60Global bubble G45, G55, G80, G120 and so on
