The S1Q-P variant features a 304 stainless steel chamber and 1/4" MNPT inlet/outlet, rated for up to 125 psi and an ambient water temperature range of 2–40 C. The ballast includes a built‑in Power On indicator and an audible lamp‑failure alert, plus lamp‑life/reminder functionality for easy maintenance. The controller measures roughly 18.6 cm x 8.1 cm x 6.4 cm, while the corresponding lamp module is about 13.5 cm x 4.3 cm x 5.8 cm, delivering a compact, integrated 12 VDC power solution for Sterilight UV purification systems in residential and light commercial water treatment applications.
