Minimize Your Electric Bill. Maximize Your Harvest.

Save up to 50% on energy costs compared to traditional lighting*

TrueSun® LED indoor grow lights were developed in consultation with award-winning master growers. These LEDs save a bundle on electric costs and emit far less heat than traditional MH/HPS lights, delivering energy savings that pay you back starting with your first harvest.

And what a harvest it will be! Our proprietary TrueSun® LEDs pamper your plants with the precise spectrum of light they need to grow and thrive. In the final flowering stage, switch on ultraviolet (UV-A) to force resin production and sweeten your yield. Now in our third generation, TrueSun® LED grow lights are the best LED grow light for quality, flavor, aroma - and energy savings.
