For indoor environments, ECO-GX is a passively cooled device, relying solely on ambient conditions (and breakthrough engineering) for heat dissipation. ECO-GX is suitable for operation in still ambient temperatures from -40°C (-40°F) to 40°C (104°F); however, we recommend at least one ft3/s of airflow to ensure efficient cooling. ECO-GX has an operating temperature of 50°C (122°F) above ambient.ECO-GX is designed as a greenhouse grow light or a sole-source indoor light, it should not be deployed outdoors or in direct sunlight.
