Q&A: 1. Are LED strip lights safe? LED strip lights are as safe as any other electrical light source when installed and used correctly. 2. Does turning LED lights on and off shorten their life?

While lifetime is reduced for fluorescent lamps the more often they are switched on and off, there is no negative effect on LED lifetime. This characteristic gives LEDs several distinct advantages when it comes to operations. 3. How many kinds color temperature you can offer?
