All of our lights turn on at dusk by default. You can then choose a lighting profile to program when lights turn off, dim or turn on again through the night. The time when they turn off or dim can be set in two ways – the time elapsed from dusk or before dawn (a duration based lighting profile) or at a specific time according to a clock in the light (real-time based lighting profile). The profile chosen at the time of order will be programmed at the factory. A lighting profile can be changed for luminaires at any time through First Light’s iOS Solar Light Control app. To change the profile of First Light bollards or other luminaires, please call us at 1 844 279-8754.
