Especially for the choice of spotlights, spotless spotlights should be chosen. Of course, if you want to save electricity, it is recommended to choose 3 watts, and the lighting can choose 5 watts.
Focus on buying skills
1, depending on the driving quality of spotlights. Generally, spotlights with good quality are products of brands or manufacturers.

3. Look at the appearance of spotlights. A good spotlight has more advantages in appearance, no matter it looks or feels smooth, there are no obvious scratches and burrs, and there is no abnormal sound inside the shaking bulb. If we find an abnormal sound inside the shaking light bulb, don't buy it, the internal parts may have been damaged.
4. Look at the spotlight lampshade and lamp body. At present, in some markets, high-quality spotlights are made of ceramic materials, because only in this way can the heat generated by the lamps be radiated and the service life will not be shortened because of excessive heat.
