    This met all my expectations for a LED. The plants seemed to explode with growth after even the first week with these new lights! Great price and Fast shipping. This is the led grow light you are looking for!

    If your like me & want to learn to grow vegetables indoors this LED is perfect. This little light is a beast & I have been using it for 3 months & it works perfectly. It uses barley any electricity, doesn’t increase your tent temperature.
