How does the sunrise and sunset ramping work on the Twinstar Inline Dimmer? When programmed to your preferred photoperiod (6, 8, or 10 hours), the controller automatically spends 10 minutes softly ramping the LEDs from off to your chosen brightness setting, and then ramps down over 10 minutes at the end of the photoperiod cycle. 2. Will this dimmer remember my settings if power drops out? The controller maintains its active program setting as long as it receives continuous power. If unplugged or during a power outage, you may need to press the timer button at your desired daily start time to re-sync the internal clock.
