Over the course of this article, we shall be taking a closer look at this specific grow light – but also at grow lights in general. For every grower, it is very important to know what grow lights are and what is the exact function that they serve.

In addition to that, there will be a detailed grow light review for the Meizhi 600W LED grow light where we shall peel the layers and discuss in detail the pros and cons of this grow light, as well as answer some frequently asked questions about it before we conclude.

Before we come to this specific grow light, let us just look at grow lights in general:

What are Grow Lights? Why Do Plants Need Them?

Under normal circumstances when a marijuana plant is growing outdoors, it grows with the help of sunlight. This light that comes from the sun helps the plants with the crucial process of photosynthesis, which basically helps them convert light into energy and helps break down various compounds inside their body which are then provided as ‘food’ to different parts of the plant, helping it grow bigger and stronger and produce more yields. Sunlight also helps produce chlorophyll and has a number of other benefits. The thing is, when you grow your plants indoors – there’s no natural sunlight. Hence, you need to recreate it.

A grow light provides not just the right kind of lighting, it also provides the right technical specifications of lighting too. Any light won’t do – it needs to be of the right wavelength at the right phase of growth. During the vegetative phase of growth plants require blue lighting and a cooler spectrum of the lighting. During the bloom phase, plants require a warmer red spectrum of light which helps boost the flowering activity.

Using grow lights, you can recreate sunlight inside a grow tent. For the best possible results, you need an LED grow light which offers a full-spectrum lighting solution. Inside a grow tent, the walls are all lined with reflective mylar layers – which then help reflect the grow light’s light on to the plant from all angles.

What are LED Grow Lights?

LED Grow lights are considered the best form of lighting. There are other types such as fluorescent lights, High-Pressure Sodium lighting, Metal Halides, and even regular light bulbs that you use in your room which offer lighting of different intensities at different wavelengths but the most optimum kind of lighting comes from LED grow lights. This is because LED lights help ensure that not only are your plants getting the right kind of light from the right distance at the right time, but they also help ensure that the operating costs are low. 

LED grow lights tend to consume much lesser power when compared to regular grow lights. They also emit a lot lesser heat. Together, both of these things make them an ideal candidate for replacing old fashioned lighting. Furthermore, another huge benefit of using these lights such as the Meizhi 600W Reflector LED grow light is that they are full-spectrum offerings and you do not have to change your light from time to time when the plant moves from vegetative phase to the flowering phase. 

Meizhi 600W Reflector LED Grow Light Review

Our review of this grow light from Meizhi will be broken up into various sections where we shall be discussing different aspects of this grow light in detail followed by a final review of the product and who is it meant for, followed by the pros and cons of this grow light.

1. Design and Durability

When you take a first look at this grow light from Meizhi, you’ll see that it is not the most attractive looking items in the market. It is one big panel divided into four smaller sub sections with a thick blue separator in between. Each of these smaller section has 30 LEDs in them, a total of 120 in the entire panel – each having an output of 5W resulting in the overall 600W output of this grow light. In terms of the physical dimensions, it measures 14.96 x 12.6 x 2.8 inches and weighs in at about 9.2 pounds. 

It is quite a thick device with a dark blue frame all around it. On all four sides you would notice that there are heat vents created so that heat can exit. On the back panel of the Meizhi 600W Reflector LED grow light, there’s the on/off switch for the VEG and BLOOM lighting modes, along with two fan outlets. Talking of the design of this grow light, one thing that stands out about it is that it supports daisy chaining, which is a great feature to have. More about it in the power section of our review. Compared to most other grow lights which are usually black or white in color, the blue body of this grow light is rather refreshing and pleasing to look at. Durability wise, too, it is a decent device and can sustain the occasional scratch or bump.

2. Spectrum and Lighting Details

Meizhi’s 600W LED grow light offers you an output of 600 Watts thanks to 120 LED lights operating at 5 watts each – giving you a final output of 600W. This is a full-spectrum LED grow light and it comes with separate switches for the vegetative and flowering lighting modes which is quite an advantage. Many grow lights tend to come with a single switch but this makes it more customizable for the phase of growth you’re in. 

This grow light has the LEDs angled in at 120 degrees which makes sure that the light covers a larger area. It also helps that there’s a reflector panel that magnifies the intensity of the light. Some people tend to be quite cautious before using a reflector panel but this one is totally safe to use and is fireproof as well. The Meizhi 600W Reflector LED grow light also features the LEDs placed with the help of a Epoxy Molding Compound (EMC) Package Technique which is great for the plants as well as the light’s body. The grow light functions at the following spectral lengths –  450~475nm 620~630nm, 650~660nm, and white.

3. Brand Value and Credibility

Now we come to something that is a little shaky territory for this grow light. While up until now we’ve seen that the durability, design and lighting are all pretty great, the brand isn’t really a major and well-known force in the markets. The company does not have a dedicated website of its own, and neither is it active on social media as their last Facebook post is from the first quarter of 2018. This adds instant doubts to the minds of the buyers. Thankfully, the company is quite active over email support and replies to your queries in a reasonable amount of time. These lights are manufactured in China and there’s always that doubt that people have when it comes to buying products from the country, especially over the past few months. The company has clarified that while their products are made in China, they are stored in warehouses in America and can reach the buyers rather quickly and in time. 

4. Coverage Offered

When the Meizhi 600W LED grow light is hung in at 18”, it ideally fits a coverage of 3ft x 3ft. Considering that you will raise it a little during other stages of growth, it should cover somewhere between 3.5 ft x 3.5ft at the most. This makes it ideal for those growers who are growing their weed on a small scale or for personal consumption. It also makes it ideal for those growers who are looking forward to buying a backup grow light for temporary usage. Using multiple of these Meizhi grow lights can also be a good idea which can help cover you upto 6x6ft with ease. 

5. Power Performance

Coming to the power performance, the grow light gives you a 600W output, but that does not mean that it also draws 600W from your wall socket. This light actually consumes only about  277W±10% and offers more than twice the output. This makes it very economical of a choice which can effectively replace an older HPS or MH light bulb. Talking about the power performance of this grow light, let us also talk about daisy chaining. 

Normally, you have to plug each grow light onto a wall socket. However, with the help of daisy chaining, you can basically plug each grow light on to the other instead of plugging each to the wall socket individually. This makes it very easy to operate these lights. As an ideal setup, never link more than three lights together to maintain safety.

6. Cooling

Cooling is an important part of all grow lights. Whenever electricity is converted into light, heat is let off. While in case of LED lights that heat is significantly lesser than other forms of grow lights, it is still there and it needs to be dissipated off. The cooling mechanism on this grow light basically consists of two fans located on the back, where one fan each has been associated with VEG and BLOOM switches. When your VEG lights are on, only one fan operates. If you turn VEG off and turn BLOOM on, the other fan will operate. If both your switches are turned on then both the fans would run. There are also a number of heat sinks on all sides that would help the heat escape.

7. Warranty, Cost, and Delivery

There’s a 3-year local warranty for all customers, along with a 30-day return period which ensures that people are protected for at least the duration of three years. The lifespan of this grow light is usually somewhere between 50,000 to 100,000 hours which makes it a great product for buyers who want to use it for a long run. The cost is usually around the $150 mark (may fluctuate based on the discounts and the delivery charges). Another great thing about it is that to make sure that nobody knows that you have ordered a grow light, the Meizhi 600W Reflector LED grow light ships in a discreet plain brown package. 

Pros and Cons of Meizhi 600W Reflector LED Grow Light

Here are some pros and cons of this grow light that we found during our review of the product.


  • Perfect for growers who want to grow a small setup of plants
  • Reflector design and angled LEDs maximize coverage
  • Intelligent heat dissipation with fans and lights connected
  • Separate VEG and BLOOM switches, support for daisy chaining
  • Good PAR Values
  • 3 year warranty period


  • Not suitable for large-scale growers

Final Rating of the Meizhi 600W Reflector LED Grow Light Review

We would rate this grow light about 4 out of 5 stars. The rating would have been a notch higher had the brand’s credibility been slightly better. Their hush-hush nature of operations and their lack of presence doesn’t really infuse a lot of trust in the buyers and this is one of the biggest disadvantages that it faces. That kept aside, this is a great grow light which delivers way above what you’d expect of it. In classic cliche, this grow light ‘packs in quite the power and punches way above its weight.’ While this is a great option for those growers who would like to use it for the purpose of a backup light, if you are a small-scale grower and would like to use it as your main light, we’d certainly back you up on that.
