Fluence SPYDR 2i 40" LED Grow Light VS ECO Farm MB660 Grow Light Bar Reviews 2021

In the world of horticulture, there’s always been one single source of light that’s best for plants: the sun. However, with the rise of hydroponic gardening and indoor gardening, in general, artificial lights have been acceptable substitutes, but the old solutions weren’t perfect. They either put out too much heat or cost too much to run. It’s a new gardening world today, though, now that high quality best LED grow lights are on the market. The question is, which ones are worth your investment? That’s where an LED grow light guide like this one is going to come in handy for you.

What should I look for when buying LED grow lights?
The best LED grow lights keep each of these components in mind:

• Power output – How many watts is the light and does it fit your needs?


• Spectrum – Does it include the complete PAR spectrum, especially blue and red?


• Quality LED chips – We suggest chips of at least 3W each, these are good for blue and red lights.


• Cooling – Are there onboard fan(s)? Or do you need to purchase any separately?

How To Choose The Best Led Grow Lights For Indoor Plants?
Color
Do you know that the light color that your plants absorb has a huge impact on the amount of energy consumed by them?
It’s because different light colors give different wavelengths. The shorter the wavelength, the more energy it provides. Each light has a specific function to your plant’s so full colors of the light spectrum is the best for them.
But if you want to optimize the light color for each growing stage of plants, here are some simple solutions:

• Far-red (720nm to 1000nm) improves the crop production


• Red light (620nm to 720nm) when combining with blue light, it helps plants produce more leaves or flowers


• Green (495nm to 570nm) encourages the chlorophyll production


• Blue (450nm to 495nm) improves the plant grow rates


• Violet (380nm to 445nm) stresses succulents and cactus promote more beautiful colors

Heat Generation

• For any LED grow lights that you’re going to buy, this factor is really important.


• LEDs aren’t created equal, meaning that their output heat is different from each other. The higher the heat output, the further it should be put away from your plants because too close distance might lead to burnt leaves or limit their growth.


• If your canopy is too low and the lights are too hot, consider installing some additional fans to make the environment cooler.

​Pros

• Full-spectrum light output


• Passively cooled light bars allow for versatile application


• Wet-rated 


• Easy vertical and horizontal installation


• Quality components throughout design


• 5-year warranty

Cons

• Dimmable feature requires use of additional adapter (not included)


• Expensive option for home grows

Pros

• Top of the line LEDs


• Fully programmable


• Remote controlled

Cons

• Price (but it’s worth it)

How many square feet does a LED grow light cover?

​500 watt      4’ x 4’ Flowering Area
1000 watt   4’ x 8’ Flowering Area
1200 watt   6’ x 6’ Flowering Area
1500 watt   8’ x 8’ Flowering Area
2000 watt  Trying to use a single light to cover over 8×8 is not recommended.
Higher wattage is not for larger coverage, but for optimal growth.

• To understand the coverage of LED grow lights, it’s important to know how the diodes inside them emit light. A traditional HID bulb such as High-Pressure Sodium or Metal Halide radiates light outward from its filament. A fluorescent bulb also radiates outward, as the gases inside the bulb become electrically charged. This is why these bulbs are turned sideways with a heat-resistant reflective backing behind them.
  
  LED light diodes, however, project light differently. Their light projects out from the actual diode itself, which is typically affixed to a small reflective backing. This focuses the intense light of the diode in a beam. This beam isn’t as narrowly focused as a laser beam, but picture a strong flashlight pointed up at the night sky. You’ll notice that the beam doesn’t get much wider further out from the light; it stays in a tight beam. 

Conclusion
There are a lot of things to consider when it comes to choosing the best LED to grow lights for indoor plants.

For many indoor home-growers, LED grow lights are game-changers. Although there’s debate over whether LEDs produce the highest yields, there’s no doubt these units are the most eco-friendly option. Add in features like easy setup and powerful light intensity, and you could see why cannabis growers are drawn to LEDs like, well, moths to a flame. 

In many respects, LED grow lights are hot because they’re cool…literally. Unlike high-intensity discharge (HID) grow lights, LEDs don’t give off a ton of energy or heat. This makes LEDs super friendly for the environment and your wallet. LEDs are also lighter and easier to set up than HIDs. Beginners have no problems plugging LEDs into an electrical socket and turning them on. Some LED lights are also quite flexible, making it easy to fit into almost any grow space. By the way，sincerely recommend eco farm led grow light for you.
