## Questions & Answers

**Q: Does This bulb turn on immediately or within seconds . I bought one for the bathroom to replace and old one and it takes a minute to warm , too long**
A: This is still a fluorescent bulb, so it takes a second or less to turn on, and then depending on ambient temperatures in the room, a minute or so to come to full brightness as any fluorescent would do.    If you want instant on and instant full brightness, you might want to consider LED technology.     I hope that helps.

**Q: one light bulb came broken**
A: Mine came broken too, Amazon replaced it in 5 days.

**Q: The current bulb is the original that came with the ceiling recessed bathroom light.  it is model f42tbx/827/a/4p.  will this work?**
A: Yes, that is a good cross, but the color, or Kelvin temps will be different.  If you want to match what you took out of there, the 2700K, then the 20887, CF42DT/E/IN/827/ECO is what you want.   The one you selected here is a cool white, or 4100K, and isn't as warm in color, it's more cool.   But either one will work with the ballast you currently have and the fixture you have.

**Q: It's dimmable?**
A: Yes, it's dimmable.  Any fluorescent with 4 pins total, is dimmable as long as there is a dimmable ballast that is compatible to go with it.  SYLVANIA makes the 51836 dimmable ballast for this.
