## Questions & Answers

**Q: Will this fit the 70's plastic table lantern that uses the D battery?**
A: Mine did, make sure you don"t have the screw in bulb type

**Q: 200% brighter is not a clear definition of how bright the bulb is.  How many lumens do they produce?**
A: I don't know because mine did not work.  I bought them for a Coleman Lantern which were supposed to be the correct replacement bulb.  They were imported from China, so that should tell you why they did not work.

**Q: What is lifetime of this bulb?**
A: depends on the use, batteries involved, etc. mine lasted quite a while on aa batteries

**Q: The description indicates "blue" light but on the picture of the product, the bulb is clear.  What does "blue" mean?**
A: typically, the white light seen from an incandescent bulb is in the yellow part of the light spectrum. some incandescents are designed to provide light in the blue portion of the spectrum, e.g., white light.
