The most basic element of lighting is the light source, with the development of lighting technology, common lighting light from the earlier fluorescent lamp, incandescent lamp to now a broader LED. In the face of such a rich lighting product, how to choose lighting light, often give trouble. For this problem, consumers should master the direction of the direction, return to its own essential demand, can make the correct choice.
In the face of different types of light bulbs such as incandescent, fluorescent lamps, how to choose?
Various light sources have their own special nature, and the bulb can be selected according to the space of use.
The number of color gentle watts used in the restaurant, bedroom, living room, study, etc. are not the same. Suitable for a warm yellow light, such as LED lights, halogen lamps, etc. Provincial light bulb.

How to interpret light bulb data, determine if it meets the requirements?
Recognize the number of watts, color temperatures, luminous flux, luminous efficiency, lamp seat specification, and variation of the lamp seat.
1 watt (W): The number of watts indicates the energy (joule) consumed per second, the higher the number of watts, the larger the power consumption, but the number of watts is not proportional to the resulting brightness.
2 color temperature (K): color temperature, the color of the light, the lower the value of the display, the more the color of the light is getting closer to yellow light, the higher the value, the closer the color of the light. When the color temperature is about 3000K, the color temperature of the bulb is yellowed; the color temperature is 5000k ~ 7000K, and the color is poor.

3 Luminous flux (LM): The amount of light flux is also known, that is, the energy released by the light source, the higher the value, the greater the brightness of the bulb.
4 Luminous efficiency (LM / W): The luminous efficiency refers to the amount of light output output from the light source consumes 1 watt power, and is the determination criterion for the light bulb.
5 Lighthouse Specifications (E): Lighthouse Specifications When you purchase bulb, you must clearly information, and measure the diameter, the lamp holder specification is measured, and the common specifications are e10, E12, E14, E17, E27, E12, E14, E17, E27, E120.
6 Variety: The higher the variance index, indicating that the color of the object under the illumination of the light source is closer to the color irradiated in the sun, the smaller the distortion index; the color of the variety of varieties, indicates the color of the object under the light source The worse the color of the sun irradiated, the distortion is large.
What is the difference between the three-to-save light bulb, LED, CFL, and CCFL?
The LED light source belongs to the point light source, the light source is concentrated, the directionality is clear, can be used for local space such as porch, corridor. As the technology of the LED lamp is increasingly mature, the high-brightness of the front-white products are removed at present, and there is also a yellow light to choose from. With the design of the light enclosure, the light of the LED lamp has approached the saving light bulb.
When using CFL bulb lighting, at least three minutes are preheated to achieve optimal light source efficiency, and the switch cannot be used frequently, affecting the service life. In contrast, the CCFL cold cathode tube and the LED lamp are highly resistant. However, the CCFL bulb tube is small, the quality is lighter, and it is necessary to use it.
