    Absolutely amazing. Instead of replacing the 8 t5 bulbs I had I picked up 4 of these and I am blown away. When I first plugged them in I about fell over they were so bright. Also happy to have all the extra space from not having to have the lights so close to the plants.
    I can’t wait to get more from ChilLED!!!

    Being diy, these boards are awesome.. easy to build, super high quality and very well thought out design.. it’s also nice they stock a lot of the little parts like nuts and bolts and connectors to complete the build. The pricing of chilled has always been extremely fair, and it’s a homegrown small company you can feel good about supporting.

    Came complete, no missing parts and installed flawlessly. I would expect no less from you guys! Turned my 4 bar into a 6 bar and my 2 bar into a 3. Thanks for making it so easy!
