The Benefits of Using LED Grow Lights

LED grow lights come with many interesting benefits. 

They are an Energy-Efficient Option

A great benefit about LED grow lights is that they are energy-efficient. Not only will this help to prevent overheating, but can prevent excessive amounts of energy from being used. Because of this, you’ll find that your energy bill will decrease significantly. 

They Don’t Overheat

LED grow lights also don’t overheat. This is due to them being made of energy-efficient materials which help the light to not produce too much energy which is usually the cause of overheating. Because of this, you won’t have to worry about your LED grow light overheating or becoming damaged if you run it for many hours at once. 

They are Compact

Another benefit about LED grow lights is that they are compact. In fact, most options, even large models, can easily it within a space without problems. However, despite being compact, many LED grow lights are made of high-quality materials. So, while they might be small, they are extremely powerful. 

They are Affordable

LED grow lights are also surprisingly affordable, unlike more expensive LEC grow lights. In fact, many often run under a hundred dollars. Despite their cheap price, they are still made of durable and heavy-duty materials making your investment worthwhile. 

What to Consider Before Buying LED Grow Lights

As mentioned above, there are many features LED grow lights usually come with. To help you narrow down your search, you should consider the following aspects. 

How Much Space it Covers

It’s always important to check to see how much space an LED grow light covers. Some might only cover a small space with light, while others will cover a large space. This is important to consider depending on the size of your growing space to ensure your plants will receive the right amount of light. This way, you can be sure your plants will grow well. 

If it Can Be Used With All Lighting Appliances

You’ll also want to check to make sure the grow light you’re interested in can be used with all lighting appliances, especially if you are using specific grow tent dimensions. Otherwise, your grow light won’t fit into these appliances making your investment a waste. Because of this, it’s vital to ensure that your LED grow light matches the lighting appliances you plan to use the light with. 

Its Wattage

Another thing to check is the wattage of the grow light. The higher the wattage, the more power the grow light will have. Depending on your needs, you’ll want to see if you want a high or low wattage. 

A high wattage is good for a large amount of plants and if you want to quickly grow plants. The downside about this though is that it tends to get hot quickly which could damage your plants. A low wattage might take some time for your plants to grow, but it will cover them evenly and won’t burn them. 

If You Can Use it with Hydroponics

If you’re looking for a grow light to use with any hydroponic systems you have, make sure it’s able to be safely used with them. While many can be, not all are able to. If you use a grow light that isn’t, it could lead to serious problems, including electric shock. Because of this, make sure to check to see if the LED grow light can be used with hydroponic systems. 

The Type of Plants it Can Be Used On

Because grow lights will vary in their color spectrum, they might not be good to use on certain plants and you have to also be aware of what types of nutrients you are adding to the mixture. For instance, certain options might need a lot of red light while others might need blue. In the end, too much or too little of a certain color can affect how well they grow. To help make sure the light can be used on the plants you have, check its color spectrum. 

The Sansi Full Spectrum LED Grow Light

This vegetative grow light runs on 15W and is made with a special ceramic and plastic bulb housing. This housing will help the light to stay cool while running and also will protect your plants from any heat emitted that might be too much for them. The bottom of this housing is made with a special hollow design. The hollow grooves at the bottom will help this light to release heat to prevent overheating from occurring.

The LED lights in this product feature the needed blue and red spectrums for your plants, but also have many other colors mixed into each light chip. You’ll find both red and blue, but also green and far red spectrums. Because each light contains these colors the emitted light will evenly cover your plants. It’s recommended that you let your plants bask under these lights for about 11 hours at a time.

This full spectrum LED grow light is made with an E26 socket which means you can just easily screw into almost any type of lighting appliance. Each bulb weighs about 1 lb. and should be hung above your plants at a distance of about 12-20 inches, depending on their certain growth stage.

The Sansi Full Spectrum LED Grow Light will cover an area of 2.8 square feet which makes it ideal to use if you have a small growing space. This light can be safely used with hydroponic systems and comes with a 5 year warranty.

The Importance of Even Lighting on Your Plants

Many grow light models come with a full spectrum, but often they emit this full spectrum with different bulb colors. While this can definitely be very helpful, sometimes the light chip location on the grow light means that certain areas of the plants might not be as fully covered in that color as other areas. One of the best features of the Sansi Full Spectrum LED Grow Light is that each bulb implements a full color spectrum. This means you won’t have certain light chips that are only blue and certain ones that are only red. With the Sansi grow light, each bulb has a full color spectrum. This will help your plants receive an even amount of the color spectrum so one area isn’t neglected with proper lighting.

The Ceramic Housing

This grow light comes with a ceramic housing. Ceramic is a helpful material that will let the grow light reach high temperatures without fears of the housing melting or overheating. Because the Sansi Full Spectrum LED Grow Light is made of this housing type, you won’t need to worry about it overheating. This is why this model is able to emit up to 350W without problems. The ceramic is also a durable material so if the light is accidentally bumped against, you don’t have to worry about it instantly breaking.

How is Far Red Different from Red?

One of the colors used in this full spectrum grow light is far red. Far red is similar to the regular red spectrum although it has its differences. Both far red and red work to help your plants with their growth, however, far red does this a little better than just regular red lighting.

The far red color spectrum is designed to help your plants sprout up quickly while producing strong stems and leaves. Far red has also been shown to help with the flowering stage because of its unique light emittance. Far red usually sends about 700-800 nm of light to your plants which is a good amount to help them grow well. The far red spectrum in the Sansi grow light will definitely help your plants grow a tad bit faster compared to the regular red lighting.

Is the Lighting Time Amount that Important?

The amount of time you let your LED grow light shine on your plants matters quite a bit. LED lights might not get as hot as other light bulbs, but they do still emit a lot of heat. Because of this, too much light on your plants can not only overwhelm them with hot temperatures, but also cause them to work too hard. If your plants are putting too much energy into growing they could end up slowly killing themselves because they’re working too hard to grow. To prevent this, it’s always important to use the right lighting time amount with your grow light.

While it might seem like 11 hours is a long time, it’s the right amount for this grow light to help your plants. Once the 11 hours are up, turn the light off to give your plants a break. The plants need darkness just as much as they need light because the darkness will help them to produce more roots. Also, keep in mind that as your plants grow you can lower this time amount so it best fits their current growth stage.

So, yes, the lighting time amount is extremely important to pay attention to if you want healthy and flourishing plants.

How to Hang Your LED Grow Light

It’s vital to ensure that you hang your LED grow light correctly. Otherwise, the light might not work correctly or could even fall. The right way to hang your LED grow light will depend on the model you choose. For the Sensi Full Spectrum Grow Light, it only needs to be screwed into a ceramic housing feature. You don’t need to worry about investing in a separate hanging kit (unless you prefer to) in order to use it. 

Taking Care of Your LED Grow Light

While LED grow lights are durable, it’s still important that you take care of them. Below are some tips to help ensure it lasts for many years.

Don’t Over-Run It

While you can keep LED grow lights on for many hours, sometimes it’s good to give the light a break. This will help it to conserve energy while also giving your plants a break from the light. You can keep the light off for an hour or two before turning it on again.

Keep it Clean

You’ll also want to make sure to keep your light clean. You can do so by taking a clean cloth and rubbing it over the light. This will help to remove any dirt or dust on it. By doing so, it won’t only clean the light, but help it to work better.


The Sansi Full Spectrum LED Grow Light is just one small bulb, but it works powerfully. It can be used in almost any lighting devices and growing areas. This grow light is filled with a wide color spectrum which will help your plants to grow strong and healthy. The unique design of this grow light also will work to prevent the bulb from overheating so you don’t have to worry about investing in many fans and cooling appliances.
