Answer: We use automotive lamps in the fixtures so the lamp life is very long. The different type bulbs vary from 7,000 hours to 24,000 hours. A standard 60 or 100 watt light bulb that you currently buy has an average lamp life of 800 to 1,000 hours. So you can see, these are very long lasting bulbs. You can purchase these bulbs from us or at any automotive store such as NAPA, Wal-Mart or K-Mart in their automotive section.
