There are two types of spotlights: low-voltage and high-voltage. Consumers should choose low-voltage spotlights, which have a longer life and higher luminous efficiency. The light efficiency of the spotlight is reflected in the power factor. The greater the power factor, the better the light efficiency. The power factor of the ordinary spotlight is about 0.5, and the price is cheap. The power factor of the high-quality spotlight can reach 0.99, and the price is slightly more expensive.
Spotlights are generally used to enhance the lighting of decorations. They are usually embedded in the ceiling or wall. The spotlights usually emit a higher temperature when working, so you must buy high-quality products, otherwise there will be safety risks.
The spotlight should be used with a transformer when it is used. The lamp beads should also be of good quality, otherwise the spotlight beads are easy to break. Think about it, the spotlight beads in the ceiling are quite troublesome to replace.
The quality of spotlights on the market varies from good to bad, and it is difficult to distinguish good from bad with the naked eye. Therefore, it is best to choose branded products and high-quality transformers that match the spotlights.
