With an overwhelming amount of LED grow lights on the market today, it can be difficult to identify which ones are good vs bad. It’s no secret that LED grow light technology is rapidly advancing.
When we have an accurate measure of our desired grow room, it’s always a good idea to pick a perfectly suitable LED for the same.
Finding one of the most reliable and best led grow light for 2X4 tent sizing might be overwhelming for some. Yeah, as we need to keep many factors in mind while figuring out one of the best.
In this article, we will reveal my picks for the Best LED Grow Lights in 2021. This list will include LED grow lights that have a flowering coverage area of 2’x4’ and are best for a full-cycle grow (from seedling through flowering). These are complete fixtures only. This list does not include DIY grow lights or lights that require significant assembly. The grow lights are listed in no specific order. For a LED grow light to make this list, we factor in: PAR output, efficiency, spectrum, light spread, diodes, drivers.

Why Choose US?
1,CARAMBOLA FULL SPECTRUM: We use 3500k white light as seedling and VEG spectrum (B:GY:R:FR=15%:45%:35%:2%),
this spectrum is same as CMH/CDM on RGYB rate . When Flower Booster Switch ON, this spectrum(B:GY:R:FR=12%:30%:48%:8%) get more red and far-red light ,
this spectrum is same as HPS on RGYB rate . Professional growers know that CARAMBOLA is great at the seedling and VEG stage, and HPS is able to ensure a very good harvest.
2, High PPF efficiency Design: Our light get 2.3µmol/J PPF efficacy even it get 50% R, and CMHCDM is 1.6 µmol/J, DE HPS is only 1.8µmol/J.
We use only 1% light decay nano-waterproof coating. All of these will let grower get 40% higher yield compare to old LED grow light.
3, Uninterrupted Actual Planting Test: We set up some grow tents in our factory , we test our lights with pepper planting from germination to fruit .
Using CMH and DE HPS to grow together , constantly adjust spectrum and efficacy with our led light , try to design best led grow light .
4, FOOTPRINT : In veg stage , 4X4ft just need 2pcs this lights , hanging 20in from the plant. In Flower stage, 4X4ft need 2–3pcs this lights , hanging 20in from the plant, and the harvest will very cost to best 1000W HPS. It must be noted that if you want to get a good harvest, try to keep your grow room at a temperature between 68°F and 86°F , especially in winter, because the heat of LED light is low.
5, MOST SAFE LIGHTS: Power drive is the core guarantee for long-term reliable operation of LED plant growth lamps.
With many years of experience in LED power supply development, we know that the control device is in a low temperature and moisture proof state.
It is a guarantee for stable and long life of the LED power supply, and it is also a guarantee to avoid fire when the power supply fails. Aluminum shell filling thermal adhesive is our standard for plant lamp power supply, which can meet the requirements of high humidity, high safety requirements and long working time.
6, BEST SERVICE- We are a professional LED light manufacturer with strong R&D team and many light tester.
