Product Description
The Keystone CAP-400HPS is a 400-watt HID ballast capacitor built specifically for High-Pressure Sodium (HPS) lighting systems that need reliable, consistent power. Using dry film capacitor technology, this component delivers stable electrical performance and proper power factor correction — which means fewer flickers, smoother starts, and longer lamp life.
Encased in a tough plastic housing, the CAP-400HPS is made to thrive in rugged environments like warehouses, roadways, and industrial outdoor fixtures. If your lighting setup demands dependability, this capacitor keeps things running on point.
