Top 1200w LED Grow Light

1. Viparspectra 1200W Full Spectrum LED Grow Light

Viparspectra is one of the most well-known grow light brands on the market. The price of the Viparspectra 1200w full spectrum LED grow light might make you do a double-take. As a popular brand, the lights tend to be more expensive than other lesser-known brands, but based on customer reviews from experienced growers, if you invest in the best, you’ll get your money’s worth. When you compare the cost of the light to the amount of energy efficiency that the light provides, as well as the long-lasting quality, you might find that it’s worth it to pay a bit more for a longer-lasting light.

The Viparspectra 1200w full spectrum LED grow light provides a full band spectrum of light that is suitable from seed to flowering stage. You retain control over the amount of light exposure your plants receive by timing the number of hours a day the light is on.

It also features a fantastic cooling system that works well for smaller grow areas, and might even replace out one of your fans. You’ll find the lamp’s built-in cooling system uses six fans w in the system tray. Because these fans are within the lighting system, you don’t have to account for extra space or calculate how many more outlets you need.

With a higher quality cooling system, your bulbs will last longer, and you will save money on other cooling equipment for your grow room.

The bulbs also include an aluminum heat sink, another cooling element to keep your lights from overheating. The heat sink helps dissipate warm air away from the components board, which is one of the first things that tends to overheat in a grow tent or room.

One of the most popular selling points of this light is that it comes with veg and bloom switches that will adjust the light flow for each growing stage. Although you’ll have to do a bit of reading on the particular strain you’ll be growing; these bloom and veg switches will help your plants get everything they can in the most crucial stages of plant growth.

How to choose 1200w led light?

Value is significant because there isn’t anyone actively investigating what these grow light manufacturers claim. Growers rely on the community around them to point out misleading advertisements and faulty systems.

Full Spectrum

What does “Full Spectrum” mean? Nearly every light manufacturer claims that their products are “full-spectrum” but how do we know that’s true? There’s a difference in quality, and the plants can tell!

Whether you’re growing cannabis outdoors, or indoors you must address the plant’s light needs before anything else. There’s a bit of debate surrounding light spectrums and how you can mimic the natural light that they would get otherwise.

What you’re looking for in a full spectrum light is:

  • Infrared (IR)
  • Ultraviolet (UV)
  • 400nm
  • 450nm
  • 500nm
  • 600nm
  • 650nm
  • 700nm

These light wavelengths work together to provide Chlorophylls and Carotenoids, which are essential during any plant’s photosynthesis process. It’s vital to have true full-spectrum bulbs as your indoor LED plant grow lights.

PAR and More

PAR is photosynthetically active radiation, which applies to the wavelengths of light that indoor plants can use. A high-quality grow light should include both infrared and ultraviolet light wavelengths to give the plant what it needs to grow.

The ultraviolet wavelengths help boost your plant’s defense mechanisms. When the plant’s defense system goes up during growing, there is an increase in terpenes, cannabinoids, and trichomes. In short, ultraviolet light leads to higher potency and also helps penetrate through the canopy more effectively. As your indoor plants grow and their leaves become denser, you get less light closer to the stalk than when they were younger. Ultraviolet rays help the light reach through the canopy and to the plant stems.

The infrared wavelengths can help increase the speed of photosynthesis. Infrared lights help stimulate plant growth, increase yield, bud growth, and trichrome production.


There is some debate among indoor growers about how light intensity affects the plants. For some, the intensity is also known as brightness. However, the term brightness is deceiving because it has nothing to do with how bright the light is to our eyes. Instead, brightness refers to the number of photons that your plants receive during a grow. Brightness can also define how deep into the canopy the light can penetrate.

A light’s wattage usually measures intensity and brightness. You can find grow lights at 300w – 2000w and beyond. However, different manufacturers may measure wattage differently. Some manufacturers refer to the amount of wattage that the light system draws straight from the wall. But others refer to the light’s ability to replace a 300w HID system, or in some cases, and HPS system. The 300W HID systems emitted up to 300 watts.

Cannabis plants require a lot of light exposure to grow. Some growers will say that the higher the intensity of light, the better the final product (when you have a proper cooling system). Typically, growers shy away from overly intense lights because they don’t have the budget, or because they’re growing only a few plants.

If you’re growing a small batch of plants, you can easily opt for a lower intensity because you’ll have less density as your plants grow.


Most full spectrum lights are suitable for use throughout the entire growing cycle. But, it can be challenging to alternate between light spectrums and prevent overexposure to certain light colors in various phases.

If you’re looking for the best value, you’re better off finding a light system that has a veg and bloom switch. These switches allow you to control the blue light, white light, and UV light as necessary. The significant difference is the changes necessary during blooming.

There’s a delicate balance, and if you’re planning on changing the spectrum during the seedling, vegetative, and blooming stages, you should spend some time reading on light transitioning.
