Just got my x4 and it’s bright! Really liking this light so far. In a 4×4 for flower mostly. Very efficient light. Looking forward to the increase in production! Definitely my go to for any future LED purchases! You can’t go wrong with Chilled Tech!

I own the chilled pucs and now have the x4. Love the coverage in my 4×4 tent and the lady’s are loving the new light. Chilled is in my opinion the best led manufacturer in the market. Had a question during assembly and it is so refreshing to reach a customer service rep in the states. 5 stars across the board!

Best light I’ve ever had, I can only run it at about 60% in a 4 x 8 tent in a 4 x 4 area. Plants are incredible a lot better than mh – hps combo. 3 amps vs 7 amps lower temps, better growth. Don’t like the misleading ship time, “ships in 5 days” It’s more like 2 weeks, both times I’ve order a light from them. But I do love the lights. I am going to buy 1 more to fill up my tent.

I’ve had this light for about a month now and since installation my plants have been reacting splendidly. The DIY kit with the push-lock connector were quite easy to put together with basic tools. I already want to upgrade for my next grow even though the X4 is great enough for a 4×4.

Excellent light, very bright and perfect spectrum for full cycle. Best part is there is no heat in the tent because I have the driver outside.

Liked the weight, the fact that the ballast is separate from the frame. This gives it more options and control over where heat is being generated. Also the same can be said for the placement of its mass. Showed up nice and quick, easy enough to put together. Grows plants.

These DIY light kits are incredible! Everything is top-shelf. From the aluminum bars to the LEDs to the driver and every part between. Also, they are American Made!
Not hard to assemble, there are some good assembly videos on the tube, watch them a couple of times then you’ll understand every part you see and where they go.
I added the push-lock connectors and I love them but they aren’t needed if you’re on a budget. The connector kit has all the parts you need, skip the extra connector, IMO.
No heat issues, having come from HPS it’s night and day. My tent stays in the 70’s with my new ventilation system.
LEDs are great no complaints can’t wait to add more bars to my X4! The driver ran from 21 to 629 watts using the dimmer. It needs a better dimmer hopefully they are working on something reasonable to help the sensitivity of the dial.
My plants are loving them and can’t wait to see what happens when I switch to flower. Started plants at 25% power as to not overpower them and stress them.
Used the flex saver to save even more money. Like I said can’t wait to add on bars and accessories and HIGHLY recommend these DIY or commercial kits.

I just purchased a four bar. I am already running a five bar in my 48″x96″ tent. The build quality on these lights is excellent. From the sheet metal work to the casting of the bars is precise. All diodes appear equal and produce less heat than the large diodes. The build is easy but you do have to pay attention assembly. But with two 600watt lights running a six inch exhaust, four inch intake and two fans. I had to change my 15amp breaker for a twenty so to run my portable AC. I am happier very satisfied with these lights so far. But I will hold my final opinion until I see how many jars are filled in 90 days.

Fast shipping and easy to put together, super bright! Pleased with my purchase and will be buying more in the future.

Top quality service and shipping was a huge plus. Most of all I love the price for what you get with the option to improve later.

Buy it.
Love the modular designs and different size options which allows you a flexibility unmatched by any other LED kit/company. I like the option to improve on my lights as I own them which will go a long way to making them stand the test of time in a market which is rapidly improving. I like the even light spread way better than my old COB’s. Cost to performance I do not think there is a better light on the market especially for the home/hobbyist small time grower. This light is amazing. I’ve watched this company put out stuff since Chilled was water/air cooling in 2016 and finally can afford their products. Much respect. Those old lights were cool looking these look even better. The below comments are unique to my situation and by all means would not be best for everyone.
There are a few things that could be improved or whose options would be nice to have imo. I would like an option/connection setup that allows you to connect the driver to the top of the lights bars. If you’re a DIY guy you could attach them to the top tracks of the bars if you were handy/willing to try it. Though it would be nice if there was a prebuilt/tested/chilled approved option to do that. It would really clean up cord placement/mess in the work area. For a lot of us I doubt the extra heat is really an issue. I can understand why you might want all your drivers and dimmers together in one spot separated from your plants ,especially if you are a larger grow, but for us <5 light small timer hobbyists its best to have everything on the light.
It would also be great if there was a sunset/sunrise option as well. I think there are outside options to do this and I have no idea how difficult this would be to build into the light. Though it would be nice to have even if it was just a simple 25% increase/decrease every 15 minutes options upon startup/shutdown.

William Sylvester –
Great light..I’ve used a lot of lights and even built my own but none of them a match to the chilled technology 😎

i love the light i heve two of them plan on buying more
John –
This kit was fairly easy to assemble (the video directions skip some steps) and get going. I already ordered 2 additional bars because I couldn’t wait any more.

This is my third growcraft I’ve purchased and I have another on the way. I don’t think there’s a reputable company out there that can beat these prices for the efficiency and build quality you produce.
Christopher J Sanderson (verified owner) –
A little bit of a wait was well worth it. Packaged well and top of the line technology and efficiency
Joshua Tune –
What can’t I say about how great this light is. It’s outperformed all my other lights at this point. My expectations were high and they have been met. Thank you so much for the great light!

I’m on day 25 of flower and I’m absolutely loving my growcrafts I got two x4 recommended by Austin for my 4×8 they are crushing it. Already planning on 2 more lol
Brandon Acaster (verified owner) –
This light is amazing so far! The first couple weeks have shown incredibly uniform growth. I didn’t have the cash to get the 6 bar set up just now but these guys set it up so additional bars can be added later! Spot on. Thanks for a great set up once again!
