Appleton KPB100HMT Explosion Proof Light Fixture

Appleton KPB100HMT is a 100-watt metal-halide ballast assembly designed to power M-90 lamps in Appleton explosion-proof lighting fixtures. Built from aluminum, this ballast is specified as a 100 W HID ballast and is sold as a ballast component rather than a complete luminaire, with input voltage compatibility of 120 V, 208 V, 240 V, and 277 V. The KPB100HMT designation identifies it as the MH ballast assembly for M-90 lamps, confirming its role in regulating current and ignition for HID operation within hazardous-area installations. Distributor catalogs list it under explosion-proof fixture accessories, including entries such as Mmiii Ballast Ltg Fix 100w Mt and UPC 781381620680, reinforcing its function as a replaceable ballast assembly rather than a full light. Catalog-verified specs include Wattage 100, Light Technology HID, and Material Aluminum, aligning with Appleton's fixture ballast components used in demanding environments.
