Questions about this item

Will the 2G11 4-pin base fit the ballast I already use for other TUV PL-L lamps?

Yes, the 2G11 single-ended base is the standard interface for TUV PL-L lamps, so existing compatible ballasts will accept this 55W model directly.

How can I verify the 18.7 W UV-C output is being delivered after installation?

Use a calibrated UV-C radiometer at the 100-hour point; the lamp should read 18.7 W UV-C radiation when operating on the correct ballast.

Does the package include a ballast or starter, or must I supply them separately?

The box contains only the 55W 2G11 TUV PL-L germicidal bulb; a compatible electronic ballast and any required wiring must be purchased separately.
