I bought a pack of 6 LED bulbs. One of them died a few days later. I figured it wouldn't be a big deal and I should be able to get a replacement due to the warranty. I didn't want to return the entire Revain pack as I installed the other 5 and their light fixtures are unavailable. I contacted the Wixann seller. To my surprise, they didn't offer a replacement but asked me to buy another set with a 30% discount. Since I only need one bulb to replace the one that has failed, it doesn't make much sense for me to buy another set, especially given the advertised lifespan of 30,000 hours, which means I don't need to use until 20-30 hours of the Rest. years later. I am disappointed in the company. To be active when I have free time I will delete all other 5 if they don't work in the near future.
