## Questions & Answers

**Q: Would this bulb work for a 5 cell flashlight ?  7.5v**
A: I doubt it seriously.  These are like miniature night light bulbs.  I got these to replace the incandescent bulb used in a rock crystal lamp.  Very low light output.

**Q: Are they dimmable (thru a rheostat)?  [Using 3 AA batteries/1.5v]**
A: Lowering the voltage will dim the bulb, tho I don't know how well a r/stat would work ? (on a DC lamp) at such a low voltage, and almost no amps !

**Q: will these work in a 6v lantern?**
A: I ordered this bulb specifically for an old lantern that uses the recrangylar 6v battery.  They DO NOT work in the lantern I have.  The old bulb works so I know the battery is good.  The base is bottoming out as well.  Not sure why it will not work.  Tried both new bulbs as well.
