Replacement UV lamps are identified by overall length, tube diameter, base (4-pin single-ended, 2-pin, or double-ended), rated power and technology: low-pressure (253.7 nm, 15–90 W, 9,000 h), low-pressure amalgam (100–800 W, 12,000–16,000 h) and medium-pressure (polychromatic, 400 W to 30 kW, 4,000–10,000 h). The table lists the catalogue lamps by length and wattage across the OEM systems cBallast supplies for, so a lamp can be located from the physical dimensions when the OEM code is unknown.
Match technology and electrical data to the installed ballast; a lamp of the right length but different arc current will not strike or will fail early. Handle with clean gloves and dispose of used lamps as mercury-containing waste.
Coverage: 113 of 113 catalogue rows with a readable size are listed (355 rows in these categories in total; the remainder can be found through the site search by part number).
