K1000 LED Grow Light

Solid light. Runs hot, not much cooling - be wary of air flow was it will be a feature and how long the product lasts. Outside of this I found it's provides a solid spectrum and fairly even ppfd across it's range. It's power hungry but we're talking tiny differences in efficiency between this and the top brands - and realistically, the price difference of the light probably put weights it. The design is solid, the ends can be angled to your desire via a simple thumb screw. They are heavy though so support them when unscrewing or they'll swing down with speed. Mounting options are solid. It's heavy so make sure you have a solid hanging shelf Dimmer works, plenty of range. Daisy chaining works. Chilli, tomato, aubergine, marigolds, sunflowers, basil and "trees if you get me bro" have all grown exceptionally well. No noise or humming. No fan noise either. 5 months of 18/6 cycle and it now blown LEDs or issues As always, be careful with Amazon led boards. So many of them have questionable safety. I haven't noticed anything here - but always be careful..

Used to bring on my Dahlia cuttings. Well made and easy to set up, with switch to set the strength of light. I have used a timer switch to operate it automatically. It works very well.

What an amazing difference these lights have made to my chili plants. Well worth getting !!

Growing is believing

Excellent light fir the money but the aluminium heat sink plate does get hot

Seller uses DPD delivery and package was left in the road two streets away after two failed delivery attempts. Edit: Not too sure about product to be fair, even with good airflow driver is quite hot to the touch even on lowest setting. May consider returning item for a refund once new lights arrive from Vivosun or AC Infinity. Will update as I go. Edit: Yeah, I'm going to buy a different product and return these lights, driver is reaching dangerous temperatures even at 25% power. Almost positive it's faulty.

Good light. Just not strong enough for my herb

don't buy these they are completely useless

Great product, I couldn't be happier with the purchase! It is bright, powerful, and very much full spectrum! I highly recommend this to anyone with plants that need a lot of light, especially if they don't want to break the bank buying a grow light! I will likely be buying more in the near future!

Nachdem ich die Lampe nun mehr als ein Jahr in Betrieb habe kann ich eine objektive Bewertung abgeben. Für meine Bedürfnisse ist die Lampe perfekt. Der Preis ist super und die Pflanzen wachsen prächtig 👍 Ab 75% Leistung wird sie zwar recht warm, aber im Winter braucht es dann keine zusätzliche Heizung und ansonsten läuft sowieso der Lüfter. Ich kann die Aglex K4000 empfehlen.

Update 09/30/2025 as things have progressed with my combination, indoor and outdoor grow, things have changed slightly. So far, I have invested approx. $2000.00 in lights and $500.00 in tents and $200.00 in fans. and $150.00 in filtration. I could have bought one light however due to the nature I was growing the plants one light was not an option. I needed to get lower on the plants in order to maximize as much yield as possible. Current lights that are being used are: 2 AGLEX K4000's; 4 Vipraspectra P2000's; and a Spider Farmer G4600 in a Vivosun 5X5 grow tent, the dark tent is a Spider Farmer 4X4, the Vivosun has way too many issues to support a dark environment for flowering Cannabis. I have 4 Vivosun fans that do quite well. After reading so many reviews on lighting, putting all my eggs in one basket seemed very risky and limiting. I also have a 3x3 Spider Farmer tent that I'll be giving to my son for a gift. He'll have to grow his own, he can't have mine lmao :) Amazon is asking for a review for the Products I've purchase. I wanted to provide an updated review. I'm a 1st time cannabis combi grower for personal use and recreation. I'm 62 years old and have always wanted to attempt growing. Having invested a fair bit of time in reading the challenges the plant presents to grow outside, which was my original intent. However, due to abnormal weather conditions I was forced to grow inside as well, when weather was not permitting. Most of the material I've read or seen of, fortunately leans more towards inside growing, commercial for recreational. A side from the nutrients it requires to grow, the environment as to which it needs to survive and provide a healthy harvest, became a point of concern. So I started with a 3x3 Spider Farmer tent, love the thing. They know what is needed for this type of growing. They ensure all aspects of the grow goes successfully, from start to finish, they do a great job of that. I had to up grade to a 4x4 and an 80" height due to the growing outside in conjunction with the inside grow. The plants are getting a 50% - 50% split time between inside and outside grow time. Last year it was a drought and this year we're near flooding. Wow So lights, lights, and lights. I thought I was going to lose my mind. Having never done this and doing my best to keep this economical, I'm on a quest for a solution. What I'm presently working with are 4 Vipar-Spectra P2000 and an Aglex K4000, after starting with one Vipar Spectra for the 3x3 and everything just evolved from there. I've literally have taken a 2 day freshly pruned semi stressed plant from the noon sun that had been basking in the sun for a few hours. Took the plant into the tent and with a little arrangement of the lights, the plant was very content, no loss of colour, no wilting leaves, no yellowing and very receptive to growth. I understand that some may rather not have to do all that, however I've read countless accounts of folks having issues with the lights and how their effecting the plants. I ran across many issues and came to the realization that I could have purchased a one trick pony for the price of the 5 lights I invested in. However the flexibility with the combined control for lighting allows improved tailoring to the plants specific lighting needs for the way I'm growing these. I don't have a canopy as per say. The flowering stage is the finish line and if it's not right then it doesn't matter about the plant, it's going in the garbage, so failure is not an option. These lights are assembled in such a way that multiple methods of control can be achieved. It does generate heat of course but not terrible considering how many lights are in the tent. I use two Vivo Sun 6" oscillating 3 speed fans and an 18" Sunbeam shop fan outside on the lower vent. That's it. My grow tent is located inside my shop that has high ceiling and plenty of ventilation. Not sure how that would work in a house. Might get a bit toasty. Now that the project is looking achievable we'll see how things from pre-flower to flower stage. Also it'll be interesting to see how long this equipment will last. So far all is good in paradise. No issues, no complaints.

Très bonne éclairage, bonne surface de luminosité par contre un peux chèredomage . Fait le djob, je le recommande.

Great light. I bought 2 of them. The heat dissipation is great. Build quality looks great. It is very brite and has adjustable brightness levels at 25%, 50%, 75%, and 100%. Good range of color for all stages of a grow. Lightweight, so it won't weigh down the top of your tent. I love how you can daisy chain multiple lights together to control them all thru one dimmer. Perfect if you have a larger grow area/tent. Easy to set up and well packaged. The light was smaller than I thought it would be but makes up for it in the brightness . It seems to be working great in my 3x3. I had an issue with one of the lights and customer service was amazing, very responsive, and fixed the issue. I think you'll be hard pressed to find a better light for the money. AC Infinity makes a comparable light but this one is much cheaper and this light has a 3 year warranty as opposed to a 1 year from the competitors. I would definitely reccomend this light.
