It uses a 15-watt UV lamp in a polished 304 stainless steel chamber (2.5 x 14.3 inches) with 1\/2-inch MNPT connections, which suits single-faucet, cottage and other low-flow applications. The BLACKCOMB 4.1 controller shows lamp status with a tri-colour LED and remaining lamp life on a 4-digit display, with audible and visual alarms.\u003c\/p\u003e\u003cp dir=\"ltr\"\u003e\u003cstrong\u003eFlow rate by UV dose\u003c\/strong\u003e\u003c\/p\u003e\u003cul dir=\"ltr\"\u003e\n\u003cli\u003e3 GPM at 30 mJ\/cm² (Luminor rating, 95% UVT)\u003c\/li\u003e\n\u003cli\u003e6 GPM at 16 mJ\/cm²\u003c\/li\u003e\n\u003cli\u003e2.4 GPM at 40 mJ\/cm²\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp dir=\"ltr\"\u003e\u003cstrong\u003eHow it alerts you\u003c\/strong\u003e\u003c\/p\u003e\u003cp dir=\"ltr\"\u003eThe LED is green when the lamp is on and within its rated life, turns yellow 30 days before the lamp expires (with a chirp in the last 7 days), and turns red with a buzzer when the lamp fails or expires.
