These bulbs won't last long

The packaging says these bulbs will last 11 years if used 3 hours a day. We used them less long and they died in less than a year!

Pros
  • New
Cons
  • Slightly torn

Defective buyer Lamps beware

I bought 4 bulbs and all were defective. I'm frustrated because I didn't use them until yesterday and now the return window is closed. It is not fair. I would happily replace if the quality is checked before shipping. Amita Clark

Pros
  • Best in niche

Hall's suggestion of checking lamp ratings before purchasing a fixture is a good one.

Agree with D. Hall. These bulbs don't last very long, but since they're the only ones that fit in our fixture, we'll keep paying for them. Hall's suggestion of checking lamp ratings before purchasing a fixture is a good one.
