Everything You Need to Know About LED Grow Lights

LED grow lights have been all the hype, especially after the government legalized recreational marijuana and medical marijuana in 10 and 33 states respectively. Nowadays, indoor marijuana plantations are popping up everywhere, and thanks to these LED grow lights and proper indoor farming techniques, marijuana farmers are making a killing from their harvests.

However, you don’t have to run an indoor marijuana farm to require these LED growing lights. These lights are great for any indoor plants like the croton or the snake plant. If you’re wondering why your neighbor’s plants are flourishing while yours are barely surviving, then these LED lights could be the reason.

In this post, we’ll be expounding on everything you need to know about these LED lights. So read on and learn what LED grow lights are, why they’re so important, and how to apply PAR when choosing the right LED grow lights for your indoor plants.

What Are LED Grow Lights?

There’s a lot you can tell from the name LED Grow Lights. The terms describe LED lights that are used to supplement or replace natural light in an indoor growing setup. Like any LED lights, these lights don’t burn a filament to illuminate, but instead, use semiconductors to produce light.

In most growing operations, these LED lights are used as the sole means of lighting with incredible results. It has a clear advantage over traditional forms of lighting because you can focus these lights on a plant. That way, no light is lost or dispersed elsewhere when in transit from the bulb to the plant.

Why Would Anyone Use These LED Lights?

With LED grow lights getting more popular by the day, it begs the question, why would anyone choose to switch to LED lights. They are, after all, more expensive than traditional lights, and the light they produce visually looks the same as the one from traditional bulbs. Here are a few reasons why LED grow lights are gaining traction across the country.

Thriving plants

The first reason you’d want these LED lights is because the light from these makes for healthy and thriving plants. If you own a plantation, there’s a high chance of optimum yield with these lights, if you also use the proper farming technique.

Highly Efficient

Compared to HID lights, these lights are about 40 to 60% more efficient. That’s because while bulbs only use about 20% to 40% of their energy to generate light, LED lights use about 40 to 60% of the same energy to produce light. This means you get more light from the same amount of energy, which will significantly lower your energy bill.

Low Heat

HID lighting systems give off a lot of light, approximately 400 degrees Fahrenheit. LED lights give out significantly lesser heat because they don’t have a filament, but instead, use semiconductors to produce light.


If you’re part of the green movement, then LED grow lights are just what the doctor ordered. Unlike other traditional bulbs, they don’t contain toxic substances like mercury, and they are 100% recyclable.

You can also settle for solar-powered variants of these LED lights for an even environmentally-friendlier solution. Some of the top solar companies back these solar-powered LED lights so you can be sure of their quality and efficiency.

Downsides to LED Grow Lights

Despite all these advantages, LED grow lights are not without their downsides. However, in most cases, the pros overwhelm the cons. Here are a few disadvantages of LED grow lights, so you can decide for yourself whether they’re worth your money.

Costlier Than Traditional Lighting Systems

The most obvious downside to these LED lights is that they are more expensive than conventional lighting. However, they are only costly in terms of initial costs or purchasing costs. In the long run, they are a more cost-effective option because you end up saving a bundle in energy costs.

Not Human-Friendly

While LED lights are incredible for plants, they’re not so great for humans. That’s because they produce bright colors like bright blue light, which may be harmful to the human eye. However, this shouldn’t be much of a problem if you have a separate room for your plants.

Don’t Age Well

LED grow lights aren’t known for withstanding the test of time. Not to say that they don’t have a long life span, it’s just that as they get older, their light quality tends to decline.

Smaller Coverage

Because LEDs produce directional light, they have a smaller coverage than traditional lighting systems. This can be both a disadvantage and an advantage depending on your purpose for the LED lights.

What Is the PAR?

When in the market for an LED growing light, “PAR” is one term that many vendors like to throw around. PAR abbreviates Photosynthesis Active Radiation, which denotes the amount of light that’s beneficial to the plant.

The PAR value for the LED grow light depends on the manufacturer. Usually, the greater the PAR value of the bulb, the more the photosynthetic light for the plant to absorb.

However, this doesn’t mean that a bulb with the largest PAR value is better than the rest. There are lots of factors that determine how effective your LED lights are. Plus, plants directly under the light will reserve the most PAR.

Plants farther away will only receive a little of the PAR.

LED Grow Lights Are Great for Your Plants

Even though LED grow lights are a bit more expensive than conventional lighting systems, they have excellent ROI. If you’re serious about your indoor plants, then these LED lights are a must-have. Before purchasing any of these lights, make sure you explore all your options and also check out online reviews to find the best one for your needs.

Apart from LED grow lights, there are so many other types of lights that you’d need for household applications. Check out our blog for comprehensive lights’ reviews.
