For LED line lamp manufacturers, the two-year warranty of LED line lamps is the warranty period, and the lifetime maintenance cost of more than two years. The product quality requires a very low damage rate, even no damage within two years. If the construction quality is good, it will take longer.
Many manufacturers say that the warranty period is 3 or 5 years, or if it is bad, it sounds fine. However, the product quality is poor, the probability of defective products is high, the maintenance is frequent, the overall use is affected, the effect is not good, and the maintenance and installation costs exceed the price of lamps. Therefore, how to choose LED line lamp products in the project is more important than how to look at the technology and quality standards of LED line lamps, the attitude of manufacturers towards after-sales service, the scale of factories and the qualifications of factories.
