King Plus 1200w LED Grow Light Full Spectrum for Greenhouse Indoor Plant Veg and Flower(Dual-chip 10w LEDs)

Up first on our list of top LED grow lights reviews, King Plus lights. They are a relative newcomer to the LED grow light scene, but their best indoor grow lights products have consistently been reviewed well ssince they hit the market. The King Plus 1200W LED is a light you seriously should keep an eye on. These LEDs can cover an area between eight to ten square feet. The main body of the light is composed of 120 10W dual LED chips which provide a more bright, dense and highly concentrated light. This means these lights have a higher rate of penetration and offers great photosynthetically available radiation (PAR) to cannabis plants encouraging their growth and increased potency, especially drung the flowering stage.

Since this is a full-spectrum adjustable height, LED grow light, it is very similar to daylight and offers the same spectrum of bands, including visible light and also UV and IR to meet the needs of the plant at all stages of its growth cycle.

King Plus 1200W LEDs have a heat sink and four fans to evenly distribute heat, and the lights are separated to prevent overheating. Most of the energy generated by these lights will be absorbed by the plant with very little waste heating to vent out. The average power consumption of this lamp amounts to 340W, making it extremely energy efficient for how much light it puts out.

The lamp is also really a breeze to install, perfect for novice growers. It comes with all the hangers, cords and carabiners included in the package, so you don’t have to stop midway in the installation because you don’t have the right size carabiner. These lights are rated for all uses, including greenhouses, indoor grow rooms or tents, so no matter what your operation looks like, this light is versatile to meet your needs. It also has well-balanced red blue ratio for optimal growth conditions.

If you’re looking for lights that are affordable and has a great balance of lumens to PAR, this should be high on your list of contenders. The only drawback is the reliability of the brand.

VIPARSPECTRA UL Certified 450W LED Grow Light, with Daisy Chain,Veg and Bloom Switches, Full Spectrum Plant Growing Lights for Indoor Plants Veg and Flower

VIPARSPECTRA has been putting out a great series of LEDs with their Reflector series aimed at a beginner grower that wants simple, yet effective full-spectrum lights at an affordable price. Apart from the 450W model, there is also a 600W and 300W model that use the same reflector technologies but have higher light intensities due to the higher wattage.

The main advantage of this light is that it is full-spectrum and uses reflector design to increase light intensity without adding extra power draw, making it efficient without sacrificing PAR or lumens. Each diode is surrounded by reflectors that reflect light that would otherwise just shine on the lamp. Since each diode is arranged evenly and the arrangement is symmetrical, this means that the reflections are appropriately distributed and create a higher intensity light throughout the coverage of the lamp.

The full-spectrum means that it’s the perfect light for any stage of the cannabis plant’s life cycle, from germination to the flowering stage. The UV and IR bands are produced by an optical lens in the light, concentrating them and increasing PARs to cannabis plants.

A huge advantage of LEDs is that they are much more efficient than other lights, like HPS lamps. The draw on the 450W is 200W, less than half of the draw of an MH HID wattage equivalent light would consume. This means that not only do you save a few bucks; the lights last longer due to less wear and tear from the higher power draw.

Despite being affordable, the VIPARSPECTRA LEDs come with a timer that can be set between veg and bloom modes, so you don’t have to set your alarm clock to turn your lights on and off. The lamp is relatively easy to install and is compact enough to be used in any small grow rooms or in grow tents.

Things to Look for Before Buying Best LED Grow Lights Top Model

When looking for the best led grow lights for your marijuana, there are a couple of factors that you need to keep in mind. You should try to fully understand your needs for growing cannabis, and how these lights can meet those needs. Then you’ll be able to choose an LED light that works best for your particular growing situation.

  • Budget: Obviously cost is going to factor into your choice. If you’re just starting, buy a cheaper option that will get the job done. If you’re more experienced and have started optimizing your operation, get the highest quality option you can afford.
  • Full spectrum: Spectrum refers to the wavelengths of light the grow light emits. A plant not only needs visible light, but also ultraviolet and infrared lights at specific parts of their development to ensure the biggest yields. Ideally, you want lights that mimic the spectrum emitted by the sun as much as possible. Most LEDs emit a full spectrum, but lower quality ones may not. Make sure the light you’re buying doesn’t just do visible light, but UV and IR also, with a well-balanced blue to red ratio. If you’re looking to grow plants that are healthy and grow them fast, you need full-spectrum lights.
  • Spacing: Each light will have a certain range of space it can cover, and it’s crucial for you to know what that range is since all your plants need to get full light, all the time. When calculating this, you need to take the dimensions of your grow space into account, along with how many plants you can fit in that space.
  • Efficiency: You want to check the market for lights that will use as little power as possible while plants grow still, but will still operate at full capacity. The lower the power draw, the longer the light will last, and the less you’ll spend on electricity. When calculating the lifespan of your best LED grow lights, remember that it will be on for extended periods, especially during the veg cycle and seed starting.
  • Light control: Amount of LED lighting for your plants will vary based on where in the grow cycle they are. For instance, plants in the veg (growing) state are typically given 18 hours of LED light per day, while flowering plants need closer to 12hours of LED lighting. While you can get away with manually turning the LED lights on and off, being able to set the time with a timer makes your life a lot easier.
