Not at all. All of our bulbs are designed and manufactured to last over 45,000 hours of use (3hr/day average), and we go to great lengths to test and ensure that our lights exceed the marked standards as far as performance and reliability go. But, like everything manufactured, there is a small defect rate, in our case, less than 1% of all of the bulbs manufactured might fail, but it's for cases like those that we have our 5-year warranty.
If your bulbs fail prematurely, please feel free to submit a request for a replacement here.
You can always call us to (858) 846-4973.
