Replacement 120 W germicidal ultraviolet lamp for the Trojan 8006AS reactor, listed as a special item rather than as the reactor’s standard catalogue lamp. The special designation means it differs from the standard 8000 series lamp, so it is worth confirming the lamp actually installed — overall length, diameter and end connector — against the unit before ordering, particularly on a reactor that has been modified or rebuilt during its life. Output falls steadily through life while the lamp continues to strike, so a germicidal lamp is replaced on hours run rather than on failure; running past the rated life is the most common reason a system drifts below its required dose. Item number 15183-0618. Supplied by cBallast on quote-to-invoice terms; lead time and freight are quoted per RFQ against the destination Incoterm.
