  3. Jenna L. (verified owner)

    Love these! They were well worth the investment. All my seedlings were healthy, green, and stout. They make very little heat and were easy to hang and turn on and off.

    Love these fixtures! There are not many quality 2-foot fixtures around that can fit into small closets & spaces. Compared to the Fluence “Ray” fixture, this light is cheaper, more efficient, better spectrum w/ Samsung L2 (recommended). Integrated driver is easier to hang & move around.

    Also this uses modular construction, it’s easy to see how you could use the frame to install a new driver & LED strip in the future instead of buying new ones and using up more materials & energy. Very well built. Feels like you a buying a light made by a craftsman. Build quality visibly higher than other LED companies.
