This light is the top seller and the best rated in the 600-watt range of grow-stimulating lights. Numerous people have lots of great things to say about this product, and I can only nod my head in agreement.

The parameters of this light are 18″x11″x3″, and the weight is almost 12 pounds. The light was designed with the growing tent in mind, so, if you have a growing tent, MarsHydro LED Growing Lamps 600W is a great choice for you.

The biggest perk of this light is a complete light spectrum from the lamps, which will significantly boost the overall health and growth rates of your plants. This light works exceptionally well for all phases of the life cycle of the plants you are growing.

There is a chip inside the light, which can control how much light the lamps give off and for which period of time. You can easily set it up and not worry about turning on/off and dimming the lamps of this LED light.

King Plus 600W is the product of the imagination and creativity of the folks at KingLED. As you might have guessed, they produce a number of LED products for various purposes. They offer a considerable range of great grow lights.
King Plus 600W is another favorite of the people: it regularly tops sales charts and customer review statistics. There is a possibility that the KingLED’s project will overtake the previous entry in popularity in the coming months. The parameters of King Plus 600W are 12.2”x8.2”x2.3” and the weight clocks in at 6 pounds.

Just like the previous light, King Plus 600W offers to its users a complete light spectrum range for utilization in plant growing. Additionally, in each socket, there are two small LED lamps, which create a more powerful light source overall for the plants. Lamps change the color that they emit, which is, of course, incredibly beneficial to the health and survivability of your plants.

Finally! Phlizon Newest 600W has received the recognition it deserves. I have been a long-time fan of this product but was honestly astounded by the fact that not a lot of people knew about it. Phlizon is a recent addition to the line of popular LED manufacturers.

Phlizon Newest 600W offers the common complete light range, but it takes even a step further than both of our previous entries. It can emit both infrared and ultraviolet light, and this skyrockets the efficiency of your growing plants to the extreme.

Just like the KingLED’s creation, Phlizon Newest 600W has two lamps in each socket. Overall, there is 120 individual LED lamps in this light. Besides the light, they emit a lot of heat that needs to be dealt with. Overheating will not only damage the lamps and the electronics, but it will lead the air heating up inside the grow tent, which will be extremely detrimental to the health of your plants.

It is fortunate that Phlizon has thought about this and installed a competent cooling solution: 2x vents and fans do their job pretty earnestly. In addition to the cooling solution, Phlizon installed two trackers into the light: humidity and temperature trackers. They affect the intensity with which the fans work; thus, regulating the temperature of both the lamps and the air inside the tent.

ViparSpectra connects with its clients and tries to satisfy even the pickiest clients` needs! That is how you get ahead of everyone else in today’s world, in my opinion. VIPARSPECTRA PAR600 600W is another excellent product from the people at ViparSpectra.

Of course, this grow light has a higher price to pay for it. Nonetheless, it is worth every penny. VIPARSPECTRA PAR600 600W brings to the table a couple of unique and useful features that justify the price easily.

The number of LED lamps is the same when comparing to the other ViparSpectra product. However, the lamps are special EpiLEDs that have an even more significant effect on the plants. These lamps emit the light that is closest to the sunlight. It is due to the lamps’ extreme range of light wavelengths. More intricate light and fewer gaps between the wavelengths better simulate the sun, as the sun emits all wavelengths at the same time.

As with the previous unit, the light has to be perpendicular to plants for it to have the best effect. Such light results in plants being denser and stronger. With VIPARSPECTRA PAR600 600W, your plants will surely blossom and flourish.

The light’s parameters are 14.1″x11.8″x3.5,” and the weight is nearing 14 pounds. This light can cover the territory of 4’x4′, which is highly impressive. Not a lot of LED grow lights can boast of covering such a large area.

When you have all switches turned on, you get the complete range of light for your plants. Individually, each of the switches controls one group of light wavelengths or, in other words, colors — one for blue, red, and white.

When do you need each light? It is super easy. Blue is for the veg phase; red is for the flowering phase. The white light is for keeping balance in the lighting. So, you can combine white with red or blue, or both of them.

Then, there is the enhanced light range of wavelengths. Folks at Bestva researched quite a bit before coming up with the new lamps onto the market. The enhanced LED lamps can cover all of the wavelengths, which results, of course, in the plants being healthier and happier.
