Adjusta-Watt LED-E Grow Light

SKU: 5c938335a7a5


The Adjusta-Watt® LED-E™ is a direct replacement for Double-Ended HPS. The footprint matches traditional DE HPS fixtures at the same mounting heights, making transitioning to LED fast and easy, and without having to change room layout or growing style. Simply switch fixtures and reap the benefits of this highly efficient and superior light source.

The LED-E focuses light more intensely over its footprint than traditional HPS, improving coverage and yields for plants around the edges. It produces significantly higher PAR over a broader spectrum than its HPS counterpart, whilst saving approximately 20% of the energy consumption. The LED-E produces virtually no heat. This reduces ventilation and HVAC requirements, further lowering operational costs.

Sol-Spec™ provides full-spectrum growth light for optimal full-term growth, and gently driven LEDs extend the lifespan of the fixture.

With manual dimming dial, and connection for Adjusta-Watt® Central Controller, or master controller. No extra modules are required.
