How to choose 1200w led light?

Value is extremely important 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 their 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 important during any plants photosynthesis process. It’s important to have true full spectrum lights for your indoor plants to reach their full potential.

PAR and More

PAR is photosynthetically active radiation which in short Is discussing only the wavelengths the indoor plants can use. We mentioned briefly above that a high-quality grow light should include both infrared and ultraviolet light wavelengths.

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 leads to greater potency, but it also helps penetrate through the canopy. As your indoor plants grow and their leaves become denser you get lesser light closer to the stalk than when they were younger. Ultraviolet rays penetrate through the canopy easily.

Infrared is another important wavelength that your plants can use. The infrared wavelengths can help increase the speed of photosynthesis. In short, this light helps stimulate growth. Infrared has recently been used to increase yield, bud growth, and trichrome production.


There is some back and forth within the growing community about intensity and what it means. First 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 which your plants are receiving. Brightness also considers how deep into the canopy the light can penetrate.

Intensity and brightness use the measure of wattage, which is how manufacturers label 300W or 600W grow lights. Unfortunately, different manufacturers use different methods of measurement. Some manufacturers refer to the amount of wattage that the light system draws straight from the wall. But others refer to the lights ability to replace a 300w HID system. The 300W HID systems emitted up to 300 watts.

Cannabis plants require a lot of light and a lot of light exposure. The higher the intensity, the better. 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 all throughout the growing cycle. But, it can be difficult 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, white, and UV light as necessary. The major 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.
