The price and purchase of LED spotlights
The price of LED spotlights
Since LED bulbs are more complicated in structure than halogen spotlights, even in the case of mass production, the product price will be higher than that of halogen lamps. But as more and more people recognize and accept, and scale production slowly spreads, the price of LED spotlights will soon reach an acceptable level. If you calculate an energy saving account when purchasing, you will find that even at the current higher price, on the basis of one year of use, the initial purchase cost + 1 year of electricity will be lower than traditional halogen spotlights. The current service life of LED bulbs can reach more than 50,000 hours.
LED spotlights to buy
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 luminous efficiency of spotlights is reflected in power factor. The greater the power factor, the better the luminous efficiency. The power factor of ordinary spotlights is about 0.5, and the price is cheap. The power factor of high-quality spotlights can reach 0.99, and the price is slightly more expensive.
Spotlights are generally used to enhance the lighting of decorative objects. They are usually embedded in the ceiling or wall. The spotlights usually emit higher temperatures when they work. Therefore, you must buy high-quality products, otherwise there will be safety risks.
The spotlight should be used with a transformer when it is used, and the lamp beads should 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.
At present, 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.
