## Questions & Answers

**Q: Anyone have any issues with tv or radio interference with these?**
A: Yes, experienced interference with some over the air tv channels' reception. The bulbs showed no interference if they are not located near the antenna cabling.

**Q: got 5th the base looks like the picture base has 1 wire ea side left pic/right have 2 ea side. Are these bulbs wired for series or parallel circuits?**
A: HI Don, These bulbs will work plugged in either way, it doesn't matter, at least in my application. I'm using them in landscape lighting, and they're great!!  I got the warm white. The higher kelvin rating tends to wash out the colors of what ever it's illuminating. Warm white or 2700 to 3000 kelvin enhances colors. The lower the number the warmer. If what you are illuminating is all white then get 5000 to 6000 kelvin.

**Q: Who makes these bulbs?**
A: I don't know who made these bulbs. There no markings indicating place of manufacture. You might try asking the seller where they're made.

**Q: Will this bulb fit in a 912 wedge bulb base?**
A: Hi, Yes these will fit perfectly fine in both 921 and 912 wedge type base.
