A: Hey puddintain,
The description is cool white, the 2700K (soft white) color shown on its webpage is incorrect.
These bases of fluorescent bulbs are considered a PL type base.
Your instructions that came with the fixture, or the box itself, should denote if it is a PL-C or PL-S type of bulb.
Refer to it to get exactly the right bulb for you.
