## Questions & Answers

**Q: Are these suitable for outdoor landscape lighting use?**
A: I use them in a waterproof housing under water in a water feature in our back deck. I think general outdoor use would depend more on the housing than on the bulb itself.

**Q: Is this dimmable ?**
A: It is an incandescent bulb, so yes, it should be dimmable.

**Q: Can this be used in my lava lamp? next to where the bulb is inserted it says to use g4 120v 35w type bulbs. thanks in advance.**
A: No. The Vstar bulb is 12 Volts not 120 volt. Check that the base of a replacement bulb is the same base as the original in the lava lamp.

**Q: Does anyone know the kelvin on these?  are they bright white or horrible yellow?**
A: Sorry, no idea what the Kelvin rating might be but the light they give off is bright white.
