Utilizing algorithmically positioned Samsung LM301H diodes, this full spectrum LED grow light is expertly designed to optimize plant yields. It boasts a proprietary driver for light dimming and can be connected to smart controllers. For even more illumination, expansion dongles (sold separately) can be used to pair with additional LED light fixtures. The unibody aluminum board, without a fan, ensures heat dissipation and prolongs the lifetime of the diodes. All components are sealed to IP-65 standards, guaranteeing peak performance in environments with higher temperatures and humidity. This LED grow fixture includes metal bar hangers and rope hangers for easy installation. It is perfect for use in grow tents with interior reflective Mylar lining to cultivate various plants, fruits, and vegetables. Part of the UIS™ platform, this product is compatible with AC Infinity app and can be connected via Wi-Fi to achieve the perfect growing environment.
