      Customer Reviews

      Based on 11 reviews
      Great results

      Plants ripened immensely after putting them under this bad boy

      Great light, overhyped

      Light produces amazing buds and flowers. Pulls the colors right out of your plant. Buy this light for the spectrum, ease of use, and quality of parts made. Not heat or height

      Good system

      Great resin was produced. Functionality was great. Coverage and light penetration is awesome. Lower buds did better than expected. I did a side by side vs 600w hortilux. Close in yield but the 600 w hps won. Overall I’m happy as long as the product lasts. Price kinda steep vs hps.

      The Real Deal Optic LED Grow Light!

      The real deal! This light will instantly improve your indoor garden. Hands down a great light! Dimmer switches for ever kind of LED it has, you have the control of the intensity of light. Which means savings on the energy bill!

      Optic 4xl

      So far it looks really good. I’m really impressed with it.
