    I received a light and set it up. The first one was problematic and the kind people at ecotech replaced it. I have had a little trouble with the interface. The light has worked well for almost a year. My corals grow well and the light works great except when I tinker.

  3. Awesome lights, unreliable control
    Performance

    My corals are growing really great under these lights. Control is beyond very unreliable. Frankly, Ecotech should drop wireless control as their implementation sucks. Almost every time I use the app, I need to reboot the system. It mostly works for a short time after. So sad I just did not buy more Kessil lights.

  4. Awesome
    Performance

    We had an aquarium built by CustomAquariums.com that was 8 feet wide, 2 ft deep and 2.5 feet high. They recommended four of these lights and I'm loving all the options you get with the programs. The lights are indeed bright and I've been acclimating our frags on the xr15 pro lights. I'd still start out low with these though as four strong lights like these might bleach out SPS corals if placed too high in the column. I love the lights though!

    Too strong, the transition was intense even using acclimation mode, might go back to g2 or switch.

    Ecotech the only reason i bought your products was because you could upgrade to the new Generation, making the retrofit possible, well the Gen3 turns out to be the last product i buy from you.

  8. Top tier/the best
    Performance
    100%
    I can't speak for MH and T5 fans (respectively I know they each have their pros and cons). I just upgraded my entry level Orbit Marine LED, to a pair of Ecotech Radion Pros Gen 4 after 2 years into the hobby. Needless to say it's been a substantial/marginal jump forward across the board in every aspect. Whether be it quality, performance, features and price, the jump is ten fold. My favorite part is the shimmering the Radions give my tank. I've since mounted my Orbit Marine LED under my main tank and above my sump. If that makes any sense lol. The Radions are the best, number 1, top tier lighting in led's. Even Number 2 is distant from Radion Pros. Don't sacrifice or compromise for cost and or features when dealing with lighting, get the Radion Pros, you'll be glad you did and so will your corals and fish!

  9. Awesome light!
    Performance

    This is the first Radion I have owned. Started acclimation at 50% which was way strong. Had to start at 30%. This light brought back colors to my corals that I have been bleached and thought to be dying. No regrets purchasing this product.
