The
HLC-2e by Custom Automated Products protects your light from Hot
Starts.” A “Hot Start” is when your ballast attempts to restart the bulb
without waiting for the bulb to cool off. The HLC-1e constantly
monitors the power going to your light. In the event of a power failure,
it will not allow the light to restart until 15 minutes after the power
is restored. This prevents your light from attempting to “Hot Start”
your bulb, preventing bulb damage and increasing bulb life.
