How to Select Led Light Bulb

Brief introduction of led light bulb market

There exists one serious problem that the factory which makes led does know how to light, while the factory which makes lighting doesn’t know making led. There are various kinds of led lights, but some can even not pass the heating test, so there are many works to be done to develop the light bulb industry to make it in a more normal way.

Advantages of led light bulb

1.Environmental protection: there is no poisonous material such as mercury in led dimmable light bulb. And the components can be easily installed and torn down, and it can be recycled by any other people instead of professional factory. 2.Solid package, it belongs to cold light source which is convenient to transport and install, it can be installed in any micro and closed equipments, taking no consideration of heat dissipation or vibration. 3.The led light bulb can operate at the rate of high speed, while if led light is switched on and off frequently, the electron-tube heater will be black. 4.Its working life can be more than 100000hours, and the ordinary family can use it in an extremely long time. 5.Luminous efficiency can reach 80Lm/w, and there are various color temperatures can be chosen with high color rendering index and color rendering. 6.It can resist impact, thunder, and it has not radiation of UV or IR.

Misunderstandings on buying led light

At present, the chips in the main market are totally different, and there exists high power, medium power, low power and COB. For example, the lumen output of one medium power is about 45lm, while the one of high power can be more than 120lm, so the glow of one led light may be the same with 3 led lights. From the aspect of cost, the chip of high power is much higher than the medium one, so the price of three led lights may be cheaper than one led light. It all depends on components. We all know that the light of LED is not involved in heat, so to the lighted objects and interior environment, there is no more heat produced. However, led is afraid of heat, light’s working life will be reduced half with the growing of temperature.
