This grow light is for intermediates, who have already learned how to grow, and want to shift themselves on a comparatively bigger growing project than going on with just two or three plants. With this grow light’s coverage area, we grew a dozen cannabis plants, and all were good. The number we are going to provide you later on in the specs part.

This 1600W model satisfied our expert testers, but not fully. There are a few things, which are not that pleasing in this grow light. We have not hidden anything from you and will discuss the negative part very well with you. If you care much about certification and trust only certified products, then let us tell you, this grow light is certified by ETL,CE, and ROHS and is cent percent safe to use.


Features of this 1600W model are balanced. They do not displease you and do not full you with joy either. You are going to come across a few issues here in the features only. So, have a keen go through.

Good qaulity LED used

320 LED chips are used in this model, and each one of them is 5W. However these chips are manufactured by a leading brand, but still, the reviews are divided when we talk about the durability. Some are happy, while some are furious and complaining that the durability of the LED chips of this grow light is the only thing to complain about this grow light. We tested it. Everything was fine. But that is not making any point.

For checking the durability, one has to use that grow light for years and years. we are not going to do that. So, you will have to decide after reading the customer reviews only. We can just give you a hint, that we have tested many grow lights, where exact same LED chips were used, and they all were highly successful with durability. The durability of these chips might be harmed due to inappropriate use also.

Full spectrum of lights

You were already expecting this, right? Yeah, this model does provide you with a full spectrum. The balance of various lights is very good in this spectrum. It is something like: 400-410nm,440-450nm,450-460nm,630-635nm,650-660nm,730-740nm and 2700K-3000K. IR and white light are present, but UV is absent. But don’t worry, the light has been successful when it comes to the yield.

Decent cooling system

You get five fans in this model, that run all together. There is a huge aluminum heat sink as well. See, do not follow the advertisers, who say that LED grow lights don’t produce heat. They do produce, but in very less amount in comparison to HID/HD/HPS lights. For cutting off this heat, the cooling system must be perfect.

Although this cooling system is highly efficient, but there is an issue as well. The high noise issue. It is not going to bursts your eardrums, but when we tested it, we found that the noise level was 20% more than the other four similar kinds grow lights that we were testing together.

Daisy chaining

This feature is a very advantageous one. An absolute beginner might not know about it may be, but intermediates and advanced level growers enjoy this feature a lot. If you are a beginner, then let us explain. With this feature, you can link many grow lights together and form a huge growing area. For example, if you have brought this one, plus a couple of more, you can attach all three of them using certain settings, and get a 3X grow area.

Decent PAR value

You might be comparing it with other models, which are close to its Watt value but also focus on the price difference. We conclude that with that much money, you are getting great PAR value. Not only that, even if we keep the price factor aside, then also there are very few grow lights, which provide with a bigger PAR output.

We have rapped the cons in this FAQ part. Besides that, you are also getting some useful info here, which we call side-info, which is tough to gain from other reviews. So, let us begin!

Can I daisy chain this model with a lower voltage models of the same series and company?

Yes, you can do that, but we recommend you not to daisy chain more than three LEDs that way, as there are certain side effects, as different models have different intensity of light. It is better to daisy chain similar models, that is more safe and beneficial.

What is the proper blue and red light ratio in this model?

Not only this, you are not going to find out the ratio with any of the models of this series, as the company says that it is their secret, and they do not want to reveal it. Our experts tried to find out. 58% Red, 40% green and blue, and a bit of IR was what they told us. But that is a rough estimation. The values can go up or down a bit.

If I buy two light, then will company provide me with a daisy chaining cord?

Now, when we talk about the LED, the durability has been an issue. Although they are Zener protected and work individually and independently, but still is a few of them goes out, it disturbs the whole spectrum. Besides that, the fans also are a bit louder than what they must be. Certain complains were there, where the fans started making even more high noise after a few months.

At this price level, this grow light is a very good choice. You can rely upon the quality. A few durability issues are there, but that happens with most of the grow lights out there. The PAR value and actual power draw please you. Till now, we were putting the features, specs, etc. in two baskets: The positive, and the negative.

The positive basket is much more heavy, and the customer reviews also say the same. Although, there are just 43 reviews there on Amazon, but the rating is healthy. 4.4/5 stars is what it is.
