Best 600W LED Grow Light Of 2020 Reviews
Choosing a best 600W LED grow light is not a difficult thing, but you also need to learn more.
Making the right selection involves having enough information about the different options available in the market and how the different lights they produce can be beneficial to your plants. When looking for Grow Light that is specifically for growing cannabis, you need to get a full cycle LED light. However, you should be aware that you may only have to use it in the vegetative and blooming stages. Other factors you should also take into account include the area of coverage, the type of chips used, the amount of heat produced among other factors.
What to Look for Before You Purchase a 600-Watt LED Full Spectrum Grow Light?
While you’re browsing the near-infinite number of 600w LED grow lights, make sure you consider these aspects before making a purchase.
Name Brand Diodes
Even if an LED manufacturer has a shining reputation, make sure that you research which diodes they’re using.
An LED grow light isn’t worth anything if the light bulbs don’t function properly, or if they go out with each passing day.
There are a handful of well-known brand names, such as Phillips, GE, Cree, Nichia, Osram, LG, and Seoul Semiconductor Co.
If you find that your preferred 600w LED grow light comes equipped with any of these brands, then you’ll likely be in the clear.
Number of Bands
Each 600w LED grow light will display the number of band wavelengths. Wavelength bands are essentially the number of color spectrums that a grow light emits.
The more bands aren’t necessarily a good thing since it increases the number of wavelengths.
As you already know, cannabis plants enjoy red, orange, blue, and white the most. These colors fall within the optimal PAR rating of 400nm-700nm.
As you include more bands, the effectiveness of the light diminishes. This is why you should find LED grow lights that are rated between 6-8 bands.
Actual Power Output
600w LED grow lights don’t emit 600w of light. This label is slightly misleading, but manufacturers are trying to say that their lights are equivalent to 600w HPS and MH bulbs.
The reality of the situation is that 600w LED grow lights only emit 90-300-watts of power. As we’ve previously mentioned, this reduces the intensity of the light but increases your energy savings.
You should always check how much power your LED unit uses. By doing so, you’ll be able to estimate how much money you’ll pay per month while using this device.
For example, the Philzon LED grow light uses 100-watts during operation, which is significantly less than that of a 400-600w HPS lamp.
UV and IR
Ultraviolet and infrared rays are quickly becoming a must-have option when cultivating cannabis. Pests and disease are becoming a problem, as more growers are growing marijuana.
Just as certain bacteria become resistant to antibiotics with increased treatments, so do diseases and pests on agricultural crops.
The agriculture industry has already witnessed this with many invasive plant species, in which they’ve grown resistant to various herbicides.
Increased exposure to a chemical sometimes has the opposite effect, and that’s what the cannabis industry is currently seeing with specific issues.
Powdery mildew, blight, spider mites, rot, and many others are becoming far more challenging to get rid of.
This is why it’s crucial that you find a 600w LED grow light that comes equipped with IR and UV light.
There are no pests or diseases that show resistance to these two natural lights, and having a variety of tools in your arsenal is always a good idea when combating these silent killers.
Built-In Fan
The vast majority of 600w LED grow lights will come with a built-in fan. The difference is how quiet it operates. Some will have dual fans, while others have a single option.
These fans are of utmost importance because they reduce the internal temperature of the device, which effectively reduces the temperature of your grow space.
If your diodes aren’t overheating, then they’ll last far longer than if they are regularly exposed to high levels of heat. This is why you must search for a 600w LED grow light with an adequate fan.
In most cases, there’s usually a trade-off. This trade-off comes in the form of discreteness. The more active the fan, the louder it is.
If you find a 600w LED grow light that’s both quiet and incredibly effective, then you’ve potentially found the holy grail of LED grow lights.
Functionality
As we’ve mentioned earlier, 600w LED grow light manufacturers have implemented a wide range of functions to enhance your cultivation experience.
These come in the form of dimming, color spectrum customization, remote controls, and secondary optical lenses.
Warranty
There’s always the potential that some of your diodes will malfunction before the estimated lifespan. This is why it’s crucial that you find a 600w LED grow light with a 2-3 year warranty.
