1 aesthetic
The lamps bought for home are used for decorative lighting, so the appearance must be beautiful. At present, the common LED spotlights are all composed of multiple luminous points, and their appearance is very different from that of traditional spotlights, so it is very uncoordinated to install them in high-end places. Therefore, the second-generation LED spotlights have an internationally patented focusing and reflecting optical system, which not only has a reflector cup as beautiful as the traditional spotlights, but also has ideal focusing and anti-glare effects. Therefore, it is suggested to choose the second generation LED spotlights for home decoration.
2, the color temperature is consistent
The color temperature of traditional LED spotlights is 2700 K. Now some LED spotlights on the market are easy to change color after a period of action, and the color temperature deviation is very serious. Therefore, it is recommended that you choose spotlights with stable and consistent color temperature, so that even if you use them for a long time, it will not change color and the decorative effect will not be reduced.
3. Color rendering index
The color rendering index CRI(Ra) directly determines whether it can truly reflect the color of the object, which is also an important factor for home decoration to express comfort under the lighting background. The national standard stipulates that the CRI(Ra) of LED lamps is ≥ 80, but now, the CRI (Ra) of LED spotlight lighting industry has basically reached 75. CRI(Ra) of some good manufacturers can reach above 85, so it is suggested that this factor must be considered when buying LED spotlights, and it is best to choose regular brand manufacturers to buy lamps.
4. Angle of light
When purchasing led spotlights, we must pay attention to the light angle, so that it can't produce glare during use, such as an angle of 20, and the light should be within this range, so that we can't see the strong light outside the illumination angle of LED spotlights, so as to ensure that the home lighting design is comfortable and suitable.
5, service life
At present, the state stipulates that LED spotlights can only be qualified if the luminous flux maintenance rate is above 70% after 25,000 hours of use, so as to ensure their long life. Therefore, it is recommended to choose a regular brand to buy, even if there is a problem, there is no need to worry about after-sales service.
