The GLE-GL is a purpose-built LED luminaire designed for safely lighting the dark cycle when growing short-day plants. Growlite's plant-safe Soft Green LEDs cannot be easily "seen" by plants allowing for critical tasks to be performed in the grow rooms during the dark cycle without the light adversely affecting the growth stage of the plant. The GLE-GL is also available with 90 minute battery backup to provide plant-safe egress lighting for grow facilities without disrupting critical photoperiod times.
