Reviews Of The Best Led Grow Lights For Your Plants

#1. King Plus 1200W LED Full Spectrum Grow Light

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

King Plus is a relative newcomer to the grow light scene, but their products have consistently been reviewed well. The King Plus 1200W is a light you seriously should keep an eye on. The main body of the light is composed of 120 10W dual-chip LEDs which provide a dense and highly concentrated light. This means that it has a higher rate of penetration and offers great photosynthetically available radiation (PAR) to plants, encouraging their growth and increased potency of plants like marijuana.

Since this is a full-spectrum 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.

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

The lamp is also really easy to install, 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. The light is 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.

If you’re looking for a light that’s 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. Since they’re a newcomer, they don’t have the brand recognition of something like BESTVA, and it’s uncertain how long the lifespan of the grow light is.




  • Affordable
  • Full spectrum
  • Easy to install and comes with all bits necessary for installation.
  • Excellent energy consumption
  • 30-day return policy
  • Relatively unknown brand
  • May have a shorter lifespan than other brands
  • No timer
  • Not waterproof

#2. VIPARSPECTRA Reflector-Series 450W Best LED Grow Lights

VIPARSPECTRA UL Certified Reflector-Series 450W LED Grow Light Full Spectrum for Indoor Plants Veg and Flower, Has Daisy Chain Function

VIPARSPECTRA has been putting out a great series of lights with their Reflector series aimed at beginner growers that want 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 energy 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 plant’s growth cycle. The UV and IR bands are produced by an optical lens in the light, concentrating them and increasing PARs to the plants.

A huge advantage of LED lights is that they are much more energy 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 money; the lights last longer due to less wear and tear from the higher power draw.

Despite being affordable, the VIPARSPECTRA lights come with a timer that can be set between vegetative 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. If you’re a beginner looking for a simple, no-frills light that is backed by a three-year warranty, this may be the light for you.




  • Full spectrum
  • Even light coverage
  • Timer
  • A reputable brand offering a 30-day money back guarantee and a three-year warranty
  • High-quality product for an affordable price
  • The light isn’t waterproof

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. By fully understanding your needs and how these lights can meet those needs, you can choose a 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, rather 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. Plants need not only visible light, but also ultraviolet and infrared lights at specific parts of their development. Ideally, you want a light that mimics 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 as well. 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 a light that will use as little power as possible while still operating at full capacity. The lower the power draw, the longer the light will last, and the less you’ll spend on power. 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: Your plants will need different amounts of light depending on where in the growth cycle they are. For instance, plants in the vegetative (growing) state are typically given 18 hours of light per day, while flowering plants need closer to 12. While you can get away with manually turning the lights on and off, having a timer makes your life a lot easier.

In Conclusion – Led Grow light

Grow lights can have a huge impact on the quality of your weed and the health of your plants. By choosing one of the top Best LED grow lights available, you can ensure you get consistent, high-quality results with power-efficient, reliable grow lamps.
