Frequently asked questions
Does this lamp need a ballast?
Yes. Like any separate-ballast compact fluorescent, it requires a ballast (electronic or magnetic) suited to its wattage, already built into your G23 fitting.
Difference between 827, 830 and 840?
827 = extra warm white (2700 K), 830 = warm white (3000 K), 840 = neutral white (4000 K). Electrical specs and base remain identical.
