Equipment compatibility

FC8T9 circline fixture-fit requirements

Philips lamp reference: 391169 / 928028403335 / FC8T9/COOL WHITE PLUS.
Match the FC8T9 circular lamp format and four-pin G10q connector to the original lamp and fixture documentation.
Manufacturer operating data: 20.5W, 61V, 0.37A; confirm the ballast is approved for this lamp type. Lamp voltage is not the building supply voltage.
4100K cool-white fluorescent lamp, not an LED circline conversion or a linear T9 tube.

Fixture suitability is determined by the specified lamp standard, ballast and available space, not a universal equipment-model list. No named fixture-model fit has been independently verified here.
