Our solar backup electric systems use special high-quality electric storage batteries.

A solar backup inverter is connected to a home electric system , we will supply detailed installation manual and videos for our customers .

Q: LED bulb PC, will the white cover affect the color temperature of the finished lamp?: Our company is doing LED lamps, about the color temperature has indeed been deviation, we call this phenomenon called drift. But there will be no 6000K drift, and there are two possibilities for you

Q: What's the reason why LED bulb gets a lot of heat?: If the radiator has a large radiating area, the temperature is low

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: What's the cause of the noise during the aging of LED bulb bulbs?: The power supply LED bulb using miniature low power switching power supply, switching transformer due to loose, and the switching frequency did not avoid the audio area, it will beep.

Q: What is the 15 Watt lumen of the LED bulb?: Each brand has different bulb qualities, probably around 1W between 60-85LM/W.

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: The heat sink temperature and the temperature of the radiator is not the same, the heat sink through thermal grease or other heat conducting medium to heat to the radiator, the temperature will not coincide. And the temperature inside and outside the radiator is also different.

Q: LED bulb w can replace 40W incandescent lamp: The standard of luminous flux according to the luminaire is lumen (LM). Incandescent lamps are w 11-12lm per 40w=440-480lm

Q: What are the characteristics of LED bulb?: Energy saving research data show that, as LED is a cold light source, semiconductor lighting itself has no pollution to the environment, and compared with incandescent lamps and fluorescent lamps, the power saving efficiency can reach more than 90%. Under the same brightness, the power consumption is only 1/10 of ordinary incandescent lamp and 1/2 of fluorescent lamp tube. If we replace 50% of our traditional lighting with LED at present, the amount of electricity we save every year will be equivalent to the sum of the total power generated by the Three Gorges power station, and the energy saving benefits will be considerable. LED, the lightning man at home, is pretty good

Q: Is it possible to manually weld LED bulb bulbs?: Well, the lights go straight up, aging, usually 24 hours of aging, testing, you have to open 10 seconds, 10 seconds off, so non-stop switching for 2 to 4 hours

Q: What brand of LED bulb is good in quality?: The price of these lamps is very low, but the quality is not guaranteed at all. The purpose of this article is to teach consumers to distinguish the quality of LED bulbs on the market so as not to be cheated. So, which brand LED bulb is good, choose a good brand, first of all should first understand how the quality of its products
