How LED Grow Lights Work

As you already know, grow lights are electric powered sources of light that mimic the natural sun rays. Therefore, LED grow lights work to enable you to grow healthy crops in places that may not have adequate sunlight.

For instance, if you live in an apartment and would like to have a few strawberries or tomatoes grow within your house, you’d realize that getting direct access to sunlight can be a hindrance. But thanks to LED grow lights, you can provide this much-needed light without having to compromise on your privacy.

You know, all plants require particular light rays for photosynthesis. This is the process through which plants make their own food using the energy from sun rays.

LED grow lights are built with the spectrum of the sun. In other words, they do not just produce light but also incorporate all the rays required for plant growth and survival.

In particular, the name LED is obtained from the term light emitting diodes. The diodes use a semiconductor to create light in an energy-efficient way.

One major advantage of LEDs is that they can always be manipulated to emit different wavelengths of light. This, therefore, gives you more power to configure the unit as per the needs of the crop species you’d like to grow.

LED Light Types

Different plants and growing conditions require different lighting systems. To give you a rough idea on what to expect, let’s zoom in to some popular grow LED light types.

  • Cob LED Grow Lights

In the past, one of the main challenges of LED lighting was that it entailed the use of huge systems. The COB LED technology provided a new window of opportunity with its compact size and low light intensity.

So how is it really different?

Well, the name COB is derived from Chip-on-Board technology. This unique technology often means that LED chips are mounted onto the circuit board effectively creating LED arrays. This unique approach means that the number of components required to emit the light is greatly reduced without compromising on light emission.

  • LED Grow Light Bulbs

It’s not uncommon to come across COB vs LED grow light comparisons on different forums. But one thing is for sure, LED grow light bulbs are closely related to COBs.

That said, grow light bulbs are designed with a heat sink metal aluminum. And because they’re just bulbs, they’re extremely easy to use around the house.

In fact, a vast majority of these bulbs are designed to fit standard E27 sockets. This, therefore, makes them extremely easy to use.

  • LED Grow Lights Strips

Although not widely popular, LED strip grow lights are a common feature in indoor gardening. These energy-efficient strips typically come with a self-adhesive light bar which can be fitted on any flat surface.

So, you can conveniently fit them inside the greenhouse or any indoor room wall. In fact, you can also hand it on the grow box shelf for ease-of-use.

For added flexibility, you can even cut these LED strips into the length needed.

LED Grow Lights Panel

VIPARSPECTRA Reflector-Series V600LED Grow light panels are the most popular variety on the market.

Why so?

Because most are made from aluminum cases which play a key role in heat dissipation. A typical benefit of these panels is that they contain a number of LED chips. It’s, therefore, possible to equip them with different IR wavelengths so you can meet your plants’ specific growth needs.

Another key advantage to panels is that they provide a wide area of coverage, unlike bulbs.

How to Choose the Best LED Grow Lights – Buyer’s Guide

Wouldn’t it be great if you found an LED grow light panel that meets your exact needs without risking your money? So, because we’re here to help you arrive at an informed choice, here are our two cents on factors to consider before making a purchase.

  • The PAR

The term PAR simply refers to the amount of light that’s available for a plant to use during photosynthesis. The reason you need to consider the PAR value of your lights is that not all forms of light are needed by plants. For instance, if you have a light bulb that generates lots of yellow and white light, it might not sustain indoor plants despite it being capable of illuminating a room.

So, what’s the recommended PAR value?

We’d generally recommend going for a PAR value between 400nm and 700nm. In fact, the closer this value is to 700nm the better. However, anything below or above that range may have counteractive effects to your plants’ growth.

  • Color Spectrum

As we’ve already noted, the color spectrum of the light used matters a lot. We’d generally recommend going for a light with a full-spectrum. However, if on a tight budget, we’d recommend going for a unit that offers at least the following bands: blue, purple, green, yellow, white, and red.

That said, a full spectrum of light is the one that ultimately provides you with all the wavelengths your plant needs to survive throughout a growth cycle.

  • The Output

The output of grow lights is best measured by checking the wattage of the unit. From the grow light reviews above, you can tell that different levels exist and those range from 300W, 400W, 600W to even 1000W. Our basic recommendation is that you should never go for anything with less than 300W.

Why this minimum requirement?

What you need to appreciate is that you can’t always get 100% power when it comes to LEDs. So, you’d still end up getting less wattage and your LED chips would blow up, easily.

Colors of the Light

Which is the best color spectrum for LED grow lights?

You might be wondering. Well, to help us understand the different types of colors, we need to first understand the color spectrum of the sun.

First off, the sun contains different kinds of light colors. Worth noting are the blue, red and white color variants. Actually, the sun’s spectrum contains the likes of red, orange, yellow, green, blue, indigo, and violet.

But for the sake of plant development, three colors are required, these being the blue, red, and white colors. In particular, plants need the blue and red wavelengths of light for photosynthesis. The white, green and yellow spectrums are also needed to support the overall growth of the leaf.

Sizes

Does size matter when it comes LED grow lights?

As it turns out, size matters a lot here. That’s because the size of the panel also influences the number of LED units available to you. In that regard, a good rule of the thumb is to always settle for an average of 32 watts worth of LED lighting per square foot.

So, if your indoor garden measures 16 square feet, it’d be a good idea to go for a unit offering a minimum of 500 watts in total. Note: Vegetative growth requires roughly about half of that wattage and, therefore, a 300-watt unit would do a great job.

Power

The power that a device has is best measured by checking its wattage. Normally, the higher the wattage, the higher the power a unit has (and also the greater its footprint on your power bill is likely to be).

That said, a 100w unit would be a little too tiny for most indoor gardening needs. However, it can help some of the resilient plants to just get by. However, if you want to maximize growth and yields, you have to limit yourself to the 300w range and above.

The 300w variety is specifically meant to light up small areas – think of 3 square feet. However, if you want a bigger yield, we’d recommend going for a 500w or 600w variant (best suited for 4 square-feet gardens).

The 1000w grow light is perfectly suited for large growth areas of 6 square feet and above. For gardens close to 10 square feet, we’d recommend nothing short of 1200w. A 1500w variant would be the best pick for gardens exceeding 10 square feet.

If you’re the curious type, you can always use your free time to make some DIY LED grow lights. However, in that case, you’d need to have a bit of background knowledge of wiring. The entire process can be a bit dangerous and in some cases, you might even face some kinds of blasts that can ruin your cord.

On average, the total cost of building a DIY LED grow light is around $150. That’s because you’d need to buy LED drivers, DC transformer, some power cords, plugs, a metal panel, AWG wires, nuts, bolts, cooling fans and so forth.

LED Grow Lights vs. HPS

HPS lights are a top competitor to LED grow lights. However, HPS lights have a cheaper initial set up cost and boast an immense amount of raw light emission. On the flipside, though, they also generate a lot of heat and are less power efficient to use. LED grow light, though cumbersome to set up, offer a better deal in the long-run.

LED Grow Lights vs. Fluorescent Light

Both LED and fluorescent bulbs are incredibly efficient in power consumption. That said, LED lights tend to last longer than average fluorescent bulbs. So, in the long-run, going the LED way provides you with a much better deal.

How to Use LED Growth Lights to Your Advantage

Perhaps the most important fact to note is that temperature can be a friend or foe depending on how it’s used. Going for a system that’s too hot could mean the plants near the source of light would get damaged.

However, you still need warm temperatures to maximize growth. So, to strike a perfect balance make sure you provide good ventilation. Besides that, make sure you have enough lights so your indoor garden is sufficiently illuminated. Last but not least, always keep your LEDs at least 18 inches away from the plants.

Care and Maintenance

To keep your grow lights functioning optimally it’s important to take good care of them. Some awesome care tips in that case include:

  • If you plan to stay in the room equipped with multiple panels it is advisable to wear glasses for led grow lights 
  • Frequently dust off the fans in your LED grow light using an air spray duster.
  • Always make sure that the room you’re using the LED lights doesn’t have too much moisture.
  • Always pay attention to the wirings and never compromise on the kind of electrical appliances you use at any given time.
  • Clean the lights using a glass cleaner – but to do that, make sure the lights are turned off and unplugged first.

You see?

It doesn’t take rocket science to keep these lights working in tip-top condition. You only need to be consistent in your care routine until you’re sure all the parts are working as best as they should.

Warranty

LED grow lights don’t come cheap. So, if you’re planning to pay for one, you should also expect it to last. We’ve seen quite a few manufacturers offering 3 or 5-year warranties. Our general recommendation is that you shouldn’t settle for anything below 1 year.

FAQs

Which color spectrum is best for my plants?

The blue and red colors are the most basic ones needed but you also need all the other bands to support a full growth cycle. So we’d recommend going for a full-spectrum grow light.

Between LED and HID grow light systems, which one burns hotter?

The HID systems traditionally burn hotter. LED systems are only warm to the touch and hardly heat up the growing area meaning no expensive cooling systems are required.

I’ve read in forums that LED grow lights don’t work, why is that?

Like in any other market, the LED grow lights market has seen the entry of below-par products. These tend to be extremely cheap. In fact, some have less than 100w of power. Such systems often fail to attain the desired results. So, provided you get a well-made system, you shouldn’t worry about it not working.
