Exodus ballasts incorporate Delayed start technology, which prohibits current rush to the lamp, and the lamp overloading. Not only does this occur when starting from cold, but also when switching between the different operating outputs.
This enables a longer life span of the lamp and a safer environment.
Random start technology allows the ballast to power on anywhere within a small, predetermined window of time (15 seconds). This allows the initial power draw of multiple ballasts to be significantly reduced as opposed to them all starting simultaneously.
