## Questions & Answers

**Q: Is this bulb fit a regular household light bulb socket?**
A: No it fits a socket called an e-17. You can purchase an e-26 to e-17 adapter here on Amazon and be able to screw it into a household light bulb socket.   But be careful, this bulb supposedly operates on 11 volts, so household voltage will immediately blow it. 
I bought 3 of these bulbs for a homemade portable UV-c sanitizer. It was difficult to find any specifications on the bulb. On set stated the bulb operates on 11 volts and another stated 14.5 volts. I just ordered the adapters, and will first try it out  with 12 volt transformer. It is supposed to draw 300 ma.

**Q: what is the actual wavelength of the light produced? in nanometers please. not just "uv-c" etc. thanks. is it 200 nm? or 253 nm ? or what? thanks.**
A: The UV-C lamp has a wavelangth of 253.7 nm.  If you need additional information contact yourfriends@guardiantechnologies.com or call 1-866-603-5900 x213 M-F 8-4:30 EST.

**Q: Does this UV bulb create negative (or positive) ions, like some of the light bulbs from other manufacturers do?**
A: This bulb does not create ions as it is a UV-C  light. If further assistance is needed please contact us at yourfriends@guardiantechnologies.com or at 866-603-5900 X213 M-F 8:30-4:30 EST.
