Hayward BALLAST UNIVERSAL ULTRA U.V. D

The Hayward Ballast Universal Ultra U.V. D is a power‑regulating component designed to drive and stabilize the UV lamp used in Hayward Ultra UV systems, ensuring the lamp receives the correct voltage and current for consistent germicidal output. It manages startup load, operating intensity, and heat control, helping extend lamp life and maintain reliable sanitization performance even under fluctuating electrical or environmental conditions. The ballast is housed in a durable casing engineered to withstand the warm, humid, chemically treated environment typical of pool equipment areas, and it includes integrated wiring for straightforward installation as a direct replacement. Because it is a compact electrical module with protective housing and attached leads, the estimated weight generally falls in the range of 0.6 to 1.2 pounds.
