    I have been actively growing for the past decade, and I have used multiple LED grow lights over that time span with just mediocre results. So I decided to upgrade to ChilLED and the results so far are staggering. Nothing but high quality craftsmanship and light is unbeatable. I would very highly suggest this light to anyone looking for an upgrade! If you want a Cadillac then is the light for you!

    I have been looking at this light for about a year, then it went on sale and had a discount code so I pulled the trigger. Arrived way quicker than I could ever have imagined (I live in Canada), well packaged and well constructed. I normally don’t grow indoors in the summer time but I had to try it out, the plants are thriving and it runs so cool. I have had a chinese blurple, Spectrum King (good for it’s time) and a couple RapidLED’s (really good), but I think this is going to be the best by far. Thanks Miles

    Purchased the X3-330 and also the X1-160 and have zero complaints in regard to the quality of the product and the customer support they provide. Always available to answer any question(s) you may have. Absolutely would buy again and will in the future.

    This is not just a light, it’s literally an investment in better growing. I upgraded from fairly high-end COB’s and there was a noticeable immediate improvement.

    Much better overall footprint coverage, no hot spots to compensate for, and the plants are really responding to the spectrum. I have an MQ-610 so verification of the actual DLI is every morning to maintain levels. Don’t hesitate on this one.

    Loving the 330. I have it for my seedlings and fresh copies they stay happy and when they’re ready they go under the 1k.

    I got this X-3 330w to go besides my fluence spyder gen. 1. I have had it now for about 4 months. Pros. It’s efficient. It’s pretty. It’s size and par map. The remote driver with a built in dimmer. Cons. It’s a little heavy. Overall I really like the light.

    I have been growing with LED’s exclusively now for over 5 years. When I tried Chilled (after trying a LOT of other fixtures) i was immediately impressed. Easy to hang, cool to the touch, doesn’t over heat my room (no AC needed), great even light coverage, increased resin production…. overall I’m thoroughly impressed. So much so, that my entire grow (that was once for led testing) has been converted over to all Chilled commercial fixtures.

    Do yourself a favor and invest in this light ! My plants are thriving under this light fixture, very low heat output, very bright with great light coverage, in fact, it is advertised as having a 2’x4’ footprint, but I am using it for my 3’x5’ tent with a wall to wall canopy in flower, and I am seeing awesome results with no dark or shaded areas what so ever. Very impressed with the quality of this light, it has definitely made me a loyal customer of ChilLED!

    Bought my second, can’t beat it, especially for the price. Great coverage, not too hot. And very professional transaction, quick turnaround. Not wasting my time building any more lights now that I know!

    Purchased the X3 with your valentines day sale and all i can say is Wow! My tent runs cooler and my ladies are loving the change from the blurple light. Tight nodes, incredible growth.

    • Vitaly Druchinin

      Thank you very much for your feedback, Darren! I’m glad the light has been performing well for you. 👍

      Please be sure to update your review with some photos closer to harvest, I’d love to see your results.

    This light is built extremely well. From the quick connect cables to the all metal body. This thing screams “High Quality” all over it. It is so bright that I have to wear sunglasses. The intensity feels like I am outside, like I might get a tan! So far it seems to be doing its job with a marked improvement over the 7 year old LEDs it replaced. All in all I am very pleased with my purchase. I will most definitely recommend.

    • Austin Jergenson

      Thank you for the great review Troy. LED tech has come a long long way in 7 years 🙂

    Great Valentine’s day price convinced me to take a closer at this light. I went to ChilLed site and was VERY impressed with the x3 330 watt stats that is perfect for my 2x4x6 tent. Then went to youtube, watched every video and read every review where ever I could find one. Pulled the trigger on a Sunday night, and rec’d the light within the week, great shipping ! Replaced a very decent LED with the X3 midway through veg on 3 autos. One plant, a zkittlez og, was very sick and ready to throw out, but after one 24 hour period under this light, it perked right up and started growing like mad the past few weeks. Now I’m convinced that this light is the best out there for a 2x4x6 tent, it’s coverage and penetration hard to beat, and my girls have never looked better !

    Finally rid of the horrible blurple. Light is well made and the prospect of being able to upgrade it is a game changer.

    This is easily the nicest light I’ve ever purchased (usually diy-build) and man was I missing out. Kicking myself for not buying a second one during the sale. Everything about the purchase, packaging, delivery, etc was also top-notch. Buy one today and see for yourself!
