LED grow lights are super-efficient grow lights they are used to grow plants indoors. In fact, NASA also (space agency) uses Full spectrum Best LED grow lights to grow plants in space.

LED growing technology is Powerful, affordable, easy to use, and consume less electric energy than other growing lights.

If you are searching for the best led grow lights in the UK then you are in the right place. Because today, I am going to share my experience of using LED grow lights. 

In this post you will learn:

What are LED grow lights?

How to use LED grow lights for growing plants?

How much they cost and electric consumption?


All-time Best LED grow lights for home growers.


Let’s Start:

Photosynthesis is the process that plants use to make their food. They absorb the sunlight and convert it into their food. But what if I tell you nowadays you can grow plants without sun rays, you can even grow them in your storeroom.


Very advanced technology is used to grow plants of all types without Sunlight and this lighting technology is called LED growing lighting technology.

You can’t even imagine the power of LED grow lights. These are used to grow all sizes of indoor plants from seeds to harvest.

And the best part is these grow lights consume very less amount of electricity.

Now it is possible for us to grow any fruit and vegetable of our choice at any time of the year.

Many other types of grow lights are also available in the market that you can use to grow plants. All of them show different results.

For example:

Full spectrum LED grow lights the UK, dimmable grow lights, high power grow lights, Special purpose grow lights are the most common types of grow lights that are mostly used for indoor growing in the United Kingdom.

If you too want a grow light for your indoor garden. I will help you to find out the most suitable light for your plants.

 just read it till the end and find out what’s best for your garden.


NOTE: It is best to choose full spectrum grow lights to avoid all future expenses. They are also called complete grow lights because they emit a full spectrum of light (similar to Sunrays). Buy once and use them for your entire life.

What are full spectrum led grow lights?

AS the name suggests, these LEDs emit the full spectrum of light. None of the lighting systems other than LEDs are able to emit a full spectrum of light. On our planet, we have two sources of full spectrum light one is natural which is SUN and the other is man-made Artificial Full Spectrum grow lights.

What is the full spectrum of light and why does this matter?

A light that covers all wavelengths that are useful for living organisms on earth (including animals, plants, etc.) is called the full spectrum of light. Sun is the only natural source of the full spectrum of light.

Here I want to make it clear that none of the Grow light can produce a light identical to the sunlight. Today most of the grow lights in the market are labelled as full spectrum lights but this does not mean they produce light identical to the sunlight. They are based on the Light spectrum of the Sun.

Man-made Artificial grow lights produce light almost similar to the sun but still, there is a big difference between sunlight (natural light) and light emitted by our artificial growing lights (artificial light).

The main advantage of grow light is they are 100% able to grow any plant easily at any time of the year.

Full spectrum LED grow lights in the UK contains infrared and ultraviolet light wavelengths. The Sun also emits IR and UV rays which are further almost filtered by the Ozone layer (protective layer of our planet). But in Grow lights, some manufacturers use 1 to 2 diodes that are there to emit IR and UV light. These lights are extremely beneficial for plants they protect them from many diseases. IR and UV light wavelengths speed up the growth rate of plants.

The diodes that are designed to emit IR and UV rays emit a very low amount of it which is not harmful to nearby humans. So do not worry if your grow light emits these wavelengths. For safety, always wear sunglasses while working near the running grow lights because they are extremely bright and can damage your eyes temporarily or permanently.

Years ago, full spectrum grows lights were costly but now you can get the best full spectrum LED grow light at a reasonable price in the United Kingdom.

Today 7 out 10 house owners in the United Kingdom grow herbs and many types of vegetables in their homes. They grow them to provide fresh and healthy food to their loved ones.

Tomatoes, Onions, Basil, Lemon, Lettuce, Carrot are very easy to grow and required less attention.

Plants cannot differentiate between artificial full spectrum grow light and natural sunlight. They absorb the light and use it for photosynthesis like they use Sunlight.

Why do plants only grow under grow light?

Plants need light for photosynthesis this is a process through which they make their food. Not any ordinary light is suitable for plant growth. There is a special light with certain wavelengths and colors of light (warm and cool) that plants like to absorb to make their food.

LED grow lights emit all colors of light whereas some top-rated grow lights give control over the spectrum of light. You can tailor the light spectrum to meet the requirements of specific plant types.

Why LED grows lights are so popular?

There are many reasons for the popularity of LED grow lights. LEDs are energy-efficient, have a longer life span, less maintenance, cheap in long term, keep production cost low, safe to use. Many more advantages make them the no.1 choice for indoor gardening.

To better understand, let’s discuss some of the main benefits.


If you have an LED grow light in your indoor garden this means you are working with the advanced and latest Grow lighting technology.


LED grow lights in the UK also called energy-saving grow lights. By installing them you can reduce your electrical bills. The lights use small Light Emitting Diodes normally all diodes are low power diodes like 3Watt, 5watt, and 10 watts. The manufacturers take many low powers but high-quality diodes and fix them on a single circuit board (motherboard) to form each LED grow lamp.

If we compare LEDs with the traditional growing technology (HPD & MD) then LED growing lights stood first in the race in all prospective. You can replace your 1200-watt HPS growing system with just a 900-Watt LED grow light which will only consume 540 watts of electric power.

Let’s understand it with another example,

1000-watt HPS light draws 1000 watts of electricity but in the case of LED 1000-watt LED light will only consume 400 to 550 wattage of power. This clearly shows the huge difference in the electric consumption of both technologies.  It clear that LED grow lights are energy-efficient grow lights in the market.

You can save as much as 50 % with a highly efficient LED grow light. The saving percentage drops to 15 % with low efficient cheap quality LEDs.

These grow lights also don’t need high power cooling systems like HPS bulbs so this also increases the savings up to 60 %.


LED growing lights are the most affordable way of growing plants without sunlight. Initially, they seem costly but when you look at their lifespan and their energy efficiency qualities, they became the most affordable Grow lights.

Cheap grow lights are not affordable grow lights they are just cheap lights made up with cheap material. Affordable lights are those lights that make your production cost low and work life long without any issue and maintenance.

Affordable Grow lights also make your electrical bills low like LED grow lights because they are designed in such a way to save your money by giving high performance at low current consumption.


 The spectrum of light is responsible for various factors like the shape of a plant, the density of flowers, the quality of fruit, and the number of fruits. Artificial LED lights emit a full spectrum of light means many wavelengths whereas others only have a single color of light which is not enough to grow healthy and productive plants.

Plants need certain wavelengths at different growth stages. For example, plants need a cooler or blue spectrum in the vegetative stage and a red or warm light spectrum in the flowering stage. Only a Full Spectrum can give you the Light which is able to grow plants in both stages.


The aim of indoor growers is to gain more and more yield every time when the harvest season comes. Plants need different light wavelengths to grow properly without LED technology none of the other lighting technology can emit the full spectrum of color which is essential for plant growth.


BEST LED Grow lights give you full control over the light spectrum. Traditional grow light functioning is based on a single spectrum that cannot be manipulated.


Many LEDs come with a dimmable feature that allows you to control the intensity of light. plants do not need the full intensity of light every time so you can dim your grow light from up to 100% this also saves more electrical energy. it is best to use dimmable grow lights because you can dim the red light during the vegetative stage and increase the light intensity in the flowering stage.


Some LED grow Lamps contain a timer that is factory fitted in the panel. Set the timer and your light will ON/OFF automatically.


They are easy to install at any growing place whether it is a small room or grow tent of any size. LED grow lights make it easy for beginners to use them without any problem. Just plug them in a power socket and turn on the electrical power, your LED light starts emitting light right at the time.


Daisy chain is connecting the light together to form a big network of growing lights. Nowadays we have so many lights in the market which give this option to the growers. In daisy chain does not need to connect each light directly into the power socket. You can connect one light with another in a series.


Some people find LED lights a little costly but in long-term use, they are less costly than HPS and other grow light. Their longer life span makes them highly affordable because once you buy an LED grow light you can use it for years without any issue.

The lifespan of a low-priced LED grow light is 50,000 hours whereas branded grow to go over the 100000 operational hours.

Having a life span of 100,000 hours is equivalent to 20 years of use.

Whereas in the case of HPS grow bulbs, you need to change them frequently because burn very frequently. This increases the overall cost of the lighting system and they only last up to a maximum of 10,00 hours.


If you want to buy a perfect piece of light that will not require any maintenance then LED is the best choice of lighting for your indoor garden. They do not need any maintenance if due to some reasons one of the Diode will stop working this will not affect the entire system. This means only failed or burned LED will not work others will do their job.


Sometimes we need to grow in humid and warm conditions where only such light can survive which like the sudden fluctuations in temperature. LED grow lamps like to work in colder temperatures. A sudden change in environmental conditions will not affect their efficiency.

The efficiency of them remains the same even in warm conditions.


This is the anther big advantage of using LED grow lights. Waterproof means you can use them in any place in wet or humid conditions. sometimes we need to use them outside when there is no enough sunlight. In such conditions only, a waterproof grow light fits best.


Consuming less electrical power means releasing less heat energy. every electrical appliance releases some amount of heat energy and LEDs also release heat but in limited quantity. Most of the energy they consumed gets transferred into light energy a negligible amount of it converts into heat.

1 watt of consumption = 3.41 BTU/hour (British Thermal Unit Per Hour).

More watts mean more heat energy

If you have a 200-watt fixture it releases 682 BTU/h of heat and a 900-watt fixture release 3069 BTU/h. but this not the case with every grow light. The type of light and efficiency changes the concept of BTU/h.

A 1200 watt HID fixture exude more heat than the 1200 watt LED grow lamp. LEDs produce ambient heat that is heat produced by the panel itself, not by the LEDs.  High heat can damage your plant permanently or in most cases it slows down the growth. So, heat management is a crucial part when you decide to grow indoors.

The problem with the HID fixtures is they produce a high amount of heat energy which can damage the plant easily. In the case of LEDs, the manufacturers do not include a diode with wavelengths past 730nm. This ensures that the diodes do not emit heat energy towards your plants.

Do a test yourself to know it better. Place your hand under the running LED light and HID grow bulbs you will feel the difference by yourself. More heat will feel under the HID which is very harmful to plant growth and a slight warm feeling under LED which is required for active photosynthesis.


LED Grow lights for indoor plants come in many different shapes and sizes. Today many big organizations are entering in the LED grow light industry. LED technology is changing rapidly and it is challenging to categorizing them. Let’s start with the present LED types and sizes.


It stands for dual in-line package light-emitting diode. DIPs are old diodes that you can see in old electronics. There are not very powerful because they do not come with any cooling system like cooling fans etc. These LEDs are not so efficient and can no longer be in use for making Grow lights. All Best LED grow lights in the UK use the latest advanced technology none of them comes with this old school technology.


These are called Surface Mounted Device grow lights. Each LED is well soldered onto a single motherboard to form a powerful grow light. Today most of the available LED lights are based on this technology. Our grow lights are the best example of this advanced lighting system. Diodes have their own optical lens to increase the intensity of emitted light. SMD LEDs come with a cooling system so that they can be used for several hours without getting hot. They are better than DIP LEDs.


COB stands for Chip-on-board LED growing light, in short, they are called cob grow lights. they are almost similar to SMDs but in comparison to them, COB uses fewer electrical components. Multiple LEDs are used to make a single chip which is as efficient as the SMDs.

In addition, they come in the following shapes


AS the name suggests these lights come in UFO-like shape. UFO grow lights are limited to cover small growing areas. Their design is responsible for their short coverage area. you will not find UFO LED bigger in size than a normal kitchen plate. Low power lights suitable for limited growth. Also, they contain their own cooling system mostly just Small fans which keep internal components under normal temperature. Do not produce excess heat. So, no heat management system is required for them.


The rectangular grow lights that you normally see in indoor gardens or in advertisements are LED grow light panels. They mostly contain the same shape in all parts of the world. Grow lights contain their in-built cooling system (heat sink and cooling fans). Multiple diodes are used to manufacture every single light. more powerful than UFO grow lights and highly efficient. It consumes less energy than HID light bulbs.

Grow panels are most widely used in indoor growing all over the Globe.

LED strip Light

These are strip grow lights and most used in those areas where growers use shelves to grow plants. LED strip grow lights are easily attached to the underside of the above shelf. This way these lights cover a large area. SMD types


The first-ever grown plant on this planet uses sunlight to grow claimed by the scientists (100% true). With the advancement in technology human start studying the growing cycle of plants. In the research, they see that plants absorb sunlight and use it to make their food they give this process a name called photosynthesis.

Now photosynthesis processes in which plants used certain wavelengths of light to make their food. When the scientists see this, they do an experiment in which they take a plant and put it under the light wavelengths which are emitted by grow lights. the results were surprising, the plants show similar growth as they show outside in the sunlight.

But this does not mean the Artificial light is better than sunlight, not at all. Farmers are still growing in open filed under the sunlight to full fill the demand of the entire world. Studies have shown that an excess of yellow light put your plants under stress. When we grow plants in sunlight, they continuously receive yellow light with other light colors.  But this does not mean sunlight putting our plants under stress.

We all agree on one thing that it is impossible to grow every type of fruit, vegetable, or herb in a single country. Every country has its own environment and according to which it is not possible to grow plants that like to grow in opposite weather.

For example, the plants that are grown in Europe cannot be grown in Asian countries due to the difference in weather conditions. so, nature balances everything.

Plants that are grown in warm countries need more yellow light are compared to the plant that we grow in the UK. This clearly shows that the yellow spectrum of sunlight does not put stress on growing plants.

LED grow lights copy the light spectrum of SUN so it is easy to grow plants under the LED grow lamp. nowadays we have grown lights that give full control over the spectrum of light means you can control the spectrum by switching ON/OFF certain LEDs. This makes it easy to grow any plant in a part of the world just give the controlled environment by growing them in grow tents under LED lights.
