Key Features of King LED 3000W Grow Light

In this King LED 3000W review, we will point out some key features of this light to help in making up your choice. These features have made this light a distinctive one from the others. And some of these may influence your decision to go with a unit of King Plus 3000W high power LED grow light.

Full-spectrum LED grow light

King Plus 3000W LED is a full-spectrum LED grow light. It can beam light that resembles natural sunlight in the most sense. It can release light at 380 nm to 780 nm bands which includes visible rays like red, blue, white, etc., and invisible UV as well as IR rays.

full spectrum color ratio

Usually, by full-spectrum grow lights the manufacturers imply that the light can provide the wavelengths between UV and IR rays. King Plus 3000W LED grow light is such a light that can dispatch all the visible wavelengths as well as the invisible UV and IR rays.  It will work as an indoor sun for your plant garden.

With various lengths of light waves, your plant will get a boosted growth and sustainability which it is supposed to have under the sunlight. Plants require different lights during different stages of their life cycle. The full-spectrum feature of this grow light ensures that the plants get the appropriate lights at every phase, whether during germination, growing, flowering, or fruiting stage.

For your reference, the plants require red light at 660 nm during germination, blue light at 400 ~ 500 nm during growing, red light at 640 ~ 700 nm during flowering and fruiting stages. The IR waves are invisible and help in formulating a nicer and quicker shift from plants’ growth to the bloom stage. You will get all these bands from King Plus 3000W LED grow light for a better planting experience.

Veg and Bloom Switches

King Plus 3000W LED grow light works on two different modes, i.e., veg and bloom. Two separate switches have been incorporated on the grow light for better operation of these modes. You can simply turn on either of the switches to get the required action as per your plants’ life cycle.

When you turn on the veg switch, the grow light will start beaming blue and white wave bands ranging from 430 nm to 660 nm. Blue lights are very important for the plants’ flourish during the time of the veg stage. This stage starts right after the seedling stage and stays up to the flowering stage. The more concentrated blue lights plants will get, the more developed roots and healthy buds they will contain.

If the bloom switch on the grow light is on, it will produce red and white rays at 430 nm – 740 nm wavelengths which are very helpful during the blooming stage of the plants. The blooming stage is basically when the plants start to show the flower buds and get fruits after that. Red light helps the plants to prevent the damage of chlorophylls.

You can also turn on both the veg and bloom switches to get an optimized result. With the dual-action, your plants will not be deprived of any light waves, and get maximum growth. Turning on the switches, you can create a natural environment for the plants in your indoor garden.

Bright Lighting Capacity

For a brighter lighting experience, King Plus 3000W LED grow light has integrated the advanced double chips Epistar LEDs with 10W capacity each. In total, the grow light has 300 bulbs which makes a 3000W capacity light. So, when you turn on the light, you’ll get the brightest light for your grow area.

When you are planning to make an indoor garden, your prime concern will be how to arrange for sufficient light without seeing the sun. To solve this issue, King LED has covered the diodes of this light with optical lenses. This helps the light in multiplying the actually generated light to a magnified scale. And so, the light gains the capability to produce a brighter light than any other grow lights in the market.

The advanced technology has made the light more efficient in throwing light at the plants at 90° and 120° focusing angles conveniently. This way, the plants can fulfill their lighting requirement for the photosynthesis process. Moreover, the ideal ratio of red and blue beams (2:8) indicated that the light can cover your plants’ health with multiple numbers of rays if required.

While bright light is helpful for the plants for stimulating the chemosynthesis process, excess light can be harmful as in many spheres of the growth cycle plants require a bit of darkness to develop the flower and fruit buds. So, you should keep that in mind when using the King Plus 3000W LED grow light.

Designed for a Larger Harvest

Talking about the effect of the King Plus 3000W LED grow light on the harvest, we must mention the PAR distribution capacity of the light. At a height of 18 inches, the grow light can send out 1582 µmol over the plants on an average. And at a height of 24 inches, the capacity hovers around 920 µmol on average.

The availability of PAR confirms that the plants are getting enough from the light source to conduct the photosynthesis process. By ensuring a proper PAR distribution, King Plus 3000W LED enables the gardeners to get their desirable harvest.

From a study, we have come to know that the average yield capacity of each of the King Plus 3000W LEDs has been found as 9 oz which is an impressive figure. Moreover, none of the samples was below 5.5 oz. This indicates that you will get at least this much using the grow light.

Energy Efficiency

King Plus 3000W LED grow light is an energy-efficient one. The manufacturer claims that with this light, the growers can save up to 80% of the light’s capacity. Arguably, the average power drawing of this light hovers around 615W. The light functions at the usual 85V to 265V AC line and fits both 50Hz or 60Hz frequencies.

The power consumption of this grow light is very low compared to any conventional HPS or MH lamps available in the market. You’ll find your utility bills very reasonable after using it for a while. Though the capacity is 3000W, the actual energy requirement is way lower than this. Moreover, the control switches of the veg and bloom modes will enable you to manage the light more efficiently to reason with the power consumption.

The LED bulbs are very optimized with Epistar’s innovative technology and the advanced drivers that have been used in this grow light. Hence, you can choose this light without any hesitation to save more on your power bills.

Advanced Cooling System

King Plus 3000W LED grow light comes with an advanced heat dissipation system. It is designed with a very strong system to deal with the heat arising from bright lighting. It has three high-speed and quiet cooling fans to blow away the temperature from the core of the light.

Below the cooling fans, there is aluminum made enriched heat sink sheltered with a toughened glass plate. This helps to evacuate the temperature from the main panel faster than you can imagine. To ease up the dissipation process, the grow light has been designed with multiple heat exhaustion outlets around the other ways of lighting panel.

This efficient cooling system protects your plants from getting burnt even at the brightest light exposure. It means your plants will get sufficient light energy at focal angles yet remain safe from any heat output. The environment inside the grow tent will remain moderate as well.

Sleek Design and Strong Construction

King Plus 3000W LED grow light is made with solid aluminum material. The construction is optimized by a minimal styled design of the main structure.
