Q:Ordinary lamp LED bulb can?

Absolutely, without any effect. It can be directly across to look at the opening of several inches.

Q:What's the cause of the noise during the aging of LED bulb bulbs?

The sound may be come from the power supply module components aging or faulty soldering and desoldering. LED long life, but may also be some problems.

Q:How did the trademark on the LED bulb go up?

Laser printing and screen printing, pad printing can be, look at the needs and equipment.

Q:LED what is the glue between the aluminum base of the bulb and the cooling aluminum?

It's best to use heat conductive glue, such as ST922.

Q:60W how many lumens and how many W LED bulb does incandescent bulb replace?

With a high quality LED light, 6W will be enough;High brightness compared to incandescent lamp, more energy saving.

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!

The milk white paint can't see light, but the transmittance is only eighty percent a few. At present, the market has not seen in line with the economic benefits of such LED ball bubble glass cover, can reach ninety percent transmittance. If any brother finds it, please let us know. We also want it very much. Oh, thank you.

Q:What's the difference between a glass cap for a bulb and a PC hood?

Weight comparisonPC specific gravity 1.2,The proportion of glass (usually glass) is 2.5,That is to say, PC is lighter in weight than glass.

Q:How to choose the bulb power?

Obviously, the designer doesn't want the ball lights to work at rated current, but there is a margin, so the light bulb will work more reliably. Because of the constant current source, current of each lamp is not 30mA, but 330mA/13=25mA, of course, the brightness of the lights will be smaller.

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
