## Questions & Answers

**Q: Will this work for 18” inch ring light or no?**
A: I used this lamp on my desk lamp with magnifier.  Worked ok .  Not sure how you measured the 18 inches.  Lamp is approximately 8 inches in diameter.

**Q: Does this bulb come with a plug or is it hard wired? i want to use it as an led ring behind my vanity mirror.**
A: It is not an LED, it's a fluorescent bulb.  It has a standard four-pin connector that must plug into a receiving fluorescent fixture.  If you don't already have the fixture, this bulb isn't going to work for you.

**Q: I am using this for photography - not for home installment. How would I "plug in" the light for my purposes? It is unclear in the description/picture!**
A: This bulb is only compatible with a certain type of receptacle.  I believe there should be a 2 or 3 hole female plug near the interior of where the bulb would attach (the male attachment is also on the interior of the bulb).  Unless you're replacing a similar bulb in a previously existing receptacle, I wouldn't recommend this bulb as it's unlike most other "screw-in" bulbs.

**Q: CRI for the 40W 16" warm white bulb?**
A: Yes

### ⭐⭐⭐⭐⭐ Review
*by C***S on 4 March 2019*

Arrived extremely quickly, was very well packed with other items in Amazon box. When I first installed this tube and turned it on, I was disappointed, thinking I had been duped, but I gave it a minute to warm up, and as I finalized the position and put the fixture cover in place, the bulb sprang to full intensity and proper light color. It seems to be as stated: a warm white, plenty of lumens output, as good as the Philips that it replaced. If it lasts six years like the Philips, I'll really be happy. For now, it seems like a winner. Can't beat it for the price I paid.
