    2 year review. I’ll talk about power, DIY, production, quality, and customer service.

    -First we purchased multiple X3-500s. Wasn’t sure what to expect from using 1000w hps. So we went watt for watt just in case.
    -These are very powerful lights. We had to dim them down. For a 5×5 area we only need between 500-600 watts total.
    -Then we bought the X3-330s, depending on hanging height distance we still sometimes dim these.
    -I see now they have the 600w, in my opinion that would be perfect for a 5×5 tent.

    -We also bought some DIY’s. Pretty easy, watched some videos as we went along. Minimal knowledge required and you save a few bucks. What’s nice now is if I need to fix anything or replace any components, I know how.

    -Production went up easily 50% and quality of product even improved. The penetration through the canopy is excellent. Much better light spread reaching to the corners of tents/rooms and they also put off much less heat. From using Hps / Mh for many years I was skeptical, but wow… only increases in all areas of production.

    -Quality of lights is excellent, powerful, and built to last. Not much else to say. Probably overbuilt, if you bump your head on them-it’ll hurt lol.

    -Customer service is above and beyond. Any questions at any time and always reply in a timely manner. They will explain everything- most recently I just inquired about the AC infinity controller and adapters. Multiple emails even in same days. They have even done special requests with mailings for me. This is top notch customer service and I feel that I am valued customer.

    -Thanks to all at ChilLed! From owner to management, production, fulfillment, customer reps and more. Every one at this place has taken steps to make sure I am happy…And I am. Thank you.

    I went with the dyi, extremely easy to assemble. I’ve waited for a few grows before giving a review. I couldn’t be happier with the results. The plants are bigger, the bud’s are fat and oily. What more is there? The light gets 5 stars.

    I am on my 2nd flowering grow using this 330 Watt 3 bar fixture. The 1st grow finished so much better than my old 600 Watt Sun Sys. with a E Hortilux bulb ever did. This for almost half the wattage is significantly better than running the HPS. The rate of bud growth and final bud size is truly amazing. New bulbs every 9 months. This is the better option in the long run. That is because this will last for so much longer without having to spend another cent. You will not have a bad grow because you didn’t realize a (normal looking) bulb was faulty. The other big benefit is the ease of changing the power/light intensity. It is saving even more electricity being able to easily change output for different stages. The efficiency is top notch too. It is a nice size and shape for my 3’x5′ area. Also, you can turn these off and back on without a big deal, that was a real pia.

    I have had this bookmarked for over a year now. I couldn’t pass up the 420 sale. Installed this light day it arrived. Already a noticeable growth acceleration. If you are seriously thinking of a new light for your setup, do not hesitate. This light is worth every penny. Absolutely crushes a 2×4 grow space. The build quality is top notch. The light intensity is just stupid. Not only is the product amazing, the customer service is phenomenal as well. I would 100 percent recommend this product and company.

      Feel so honored! Thanks for taking the time to leave this review. Happy to hear about your great experience Derrick 🙂

    Growcraft X3 – 330W LED Grow Light – Commercial Grade This light is exceptional. 1st grow was as good as the 600 Watt HPS it replaced. This is my 2nd LED and this one is the best bang for your buck.
    I took a long time deciding between Electric Sky and ChilLED and I am so glad I did. This fixture is light and fills my 2.5′ x 4.5 room fine. This LED grows better buds over any of my 5 years of HPS growing. Less heat, more head room and no venting the fixture outside. And did I mention half the electricity usage!

    • Gabrielle

      So ecstatic about your experience! Thanks for taking a chance with ChilLED and making the switch to LEDs 🙂 Happy growing Richard!

Thank you Chilled Tech …

    I am new to indoor growing so I researched LED lights for about six months. I am using a GCx3-330w in a 3×5 space where it has exceeded my expectations. I am already a return customer and also now have two x3-550w lights as well. I bought all of my lights during sales which made them an even better purchase.

    After a ton of research into LED lighting I purchased my V3. Delivered on time and wow what a light. Fit and finish was flawless and precise, not a rough edge or poor fit anywhere. Easy to set up and puts out some light, cant wait to get a grow going soon. I ran her full power for a couple days, runs nice and cool and only raised temp in tent 4 deg f . Outstanding ChilLed staff for excellent workmanship and customer service. I see this company going places and no doubt your going to be around for the long haul.

    This light is AMAZING !!! So easy to setup and I love that you can get an extension for the driver. The results I’m getting are insane! Just bought the X1 160W for another project! Up next is the guardian system with the spectrum control kit!

    Bought one of these last year for a 2×4 tent and it’s been crushing it every round. Bought another one recently for another 2×4 box and glad I stuck with ChilLED vs. the competitors. Being able to dim and have the controller sit outside the box are just more pluses to this great light.

    The customer service was great, the shipping was prompt as well. I’ve had other DIY LED lamps and this one blows them away. Super simple to assemble, takes about 5 minutes. I had a couple questions for customer service after I received my lamp and they were great
    Highly recommended!
