Maybe not as familiar as Viparspectra or Marshydro, but this 450W model of Meizhi is giving such a head breaking competition to 450W models of not only those two companies, but many others as well.

Yes, at that price level, it fulfills almost all expectations of yours. Remember, the darker side is also there, which we will expose later on in this review.


This grow light really pleases quite deeply with the number of features that it provides you. Here, we will be mentioning them, explaining them and pointing the ways how they prove themselves useful to you. Let us proceed.

Highly durable LED

This LED has got ETL certification. The LED is durable up to 100,000 hours. When we checked the consumer reviews, we found that the dissatisfaction rate regarding the durability is comparatively lesser than other 450W models. That determines that there are very less chances that you might feel the need of utilizing the warranty.

Perfectly constructed cooling system

The cooling system of MEIZHI R450 450W Reflector-Series LED Grow Light is brilliantly constructed. When you look at the shape and the size of the blades of the fans, you will be impressed. No high noise issues. Besides that, these fans are extremely powerful and maintain the right temperature in your grow tent.

These fans, along with heat sinks, form an extraordinary cooling system, which allows you to keep this light on for almost 19 hours a day.

Full spectrum

It is a full spectrum light. It consists of LEDs, which are red (650-660nm), green (620-630nm), Infrared (730nm), blue (450-475nm) and white (5500-6500K). You need nothing else now! When you look at this grow light working, you might feel as if a few bulbs are not working. But it isn’t like that.

Those bulbs are emitting IR and UV, which a human eye cannot see. MEIZHI R450 450W Reflector-Series LED Grow Light is like a small electronic sun in your grow tent, which doesn’t burn your leaves!

Now, when we talk about utilizing the spectrum, the light is already doing its job, but your job is to place this grow light at a proper distance. The max distance that we suggest is 30 inches, while the minimum distance is 18 inches.

Daisy chaining ability

We already expected daisy chaining feature in this grow light. You can link this light with other two, or maximum three, to expand the area for plant growth. So, never feel limited with the grow area that you are getting with this grow light. By the way, if you are searching for bigger gardens, then buy something else, but if you are a small scale indoor grower, then daisy chaining is no less than a boon!

Yes, that is confusing for sure. See guys, Amazon increases the selling price when the item is less in the stock. It might happen that you might see the price as $170 on Monday, and it rises over $300 on Saturday. That is because the item runs out of stock.
