For any indoor gardeners, LED Grow Lights seem to be crucial than ever, considered to be of more paramount importance than sunlight. This is mainly because LED Grow Lights can offer a continuous light flow, generate a negligible amount of heat, and ensure plants’ best-growing environment and criteria.

The overwhelmingly particular thing about LED grow lights is the manufacturing of blue light and red light, two essential sources of energy to grow plants. Those lights remarkably contribute to the seedlings, the growth of young plants and are great support in root and bulb development.

For such impressively positive influences and advantages, are you thinking of purchasing one for your lovely garden? However, with a wide variety of products on the market, you are still left undecided with choosing which one. That’s the reason we are here! Let’s flick through our best LED Grow lights Reviews UK right now!

What Is LED Grow Lights?

If you are a frequent gardener, LED grow lights seem to be no stranger to you, as they are an indispensable part of any gardening corner, especially a commercial one. As the name suggests, LED or light-emitting diode grow lights are small electronic components, featuring two different materials like a negative charge and a positive one.

When a current of electricity runs through the lights, these two materials are likely to appear, then collide to release energy in the form of photons. Those photons are strong enough to provide the plants with a sufficient amount of heat and light, but light enough not to cause any serious harm or damage to the budding or seedling.

For these tremendous impacts and overwhelmingly impressive performance, LED grow lights have played a crucial part in modern agriculture development and are likely to replace all old-fashioned and ineffective farming methods shortly.

Types Of LED Grow Lights

There are three main types of LED grow lights, most commonly used for growing plants. Each of them boasts unique and wonderful features, thus suitable and best for different situations.

Spread style

It seems that the LED grow lights’ coverage depends on their size; therefore, big-sized LEDs can cover a larger gardening area. Nevertheless, if you choose a spread type, you will likely receive an equally large gardening area with much smaller LEDs.

Two prime examples of this type are quantum board and spider LED. Specifically, the former has relatively low wattage diodes but seems to spread out over a large area on the board. The latter one is set on a panel with various branches like a spider net. As it is of premium quality and shows excellent features, it comes at such a high price, and not all gardeners can afford it.

Traditional panel

It is not surprising that standard LED lights have small to medium wattage diodes, as the lamps look more compact and small. Most LEDs at this reasonable and affordable price like this one tend to have the same size and design.

They are halfway between a quantum board and a COB style light; therefore, they are a brilliant choice for those working on a medium-scaled gardening project or a limited budget.

COB style

This new style is a revolutionary step in modern agriculture, as it shows advanced technological features like incredibly bright and intense COB or chip onboard LED bulbs. Those LEDs can produce more light and a more excellent performance than any other type of LED.

Although they come at such a relatively high price and consume a significant amount of electricity, COB LED grow lights are one of the best types and well-known for penetrating the plant canopy, which consequently boosts plants’ development.

AutoCOBs

If a COB style grow lights are made from various COB LED bulbs to ensure a proper working condition, an autoCOB can work well with only one COB. Nowadays, it is not uncommon to spot an autoCOB, as this type has rapidly gained popularity thanks to its wide light spread and a considerable amount of heat and light.

Moreover, if you intend to grow different types of plants and flowers of various sizes simultaneously, AutoCOBs will be an excellent choice.

How To Choose The Best LED Grow Light?

As the market seems to offer you an overwhelming list of LED grow lights, making you unable to decide wisely. Here are some aspects that you should take into account when considering a LED grow light:

Light intensity

Light intensity is one of the top considerations when choosing a LED grow light, as it directly influences the development and germination of plants. To have a healthy and well-grown plant, you must generate a perfectly adequate heat and light amount. Too much or too little is not advisable.

What concerns you about light intensity is not the extent to which the human’s eye is affected by the light, but the plants themselves. This means how much protons are generated and recommended to promote the growth and flowering.

To check the light intensity to make sure that it is suitable for your garden, flick through the manufacturers’ recommended footprint. If you find this footprint so subjective and unable to reflect the real figure, the PPF reading and PAR chart are highly recommended.

Spectrum

There are two main types of spectrums on the market: targeted and broad. The former spectrum emits specific wavelengths, which are also called mono or narrowband ones. These wavelengths tend to ensure an efficient photosynthesis process.

On the other hand, the broad-spectrum, or white-light one, is more popular among gardeners than its counterpart, thanks to the following reasons. Besides its great efficiency, this spectrum also offers a great aesthetic thanks to the white light. Under the white light, the plants look more attractive and natural. Thus it is easier for gardeners to diagnose any pests or diseases.

Each spectrum has its unique advantages, suitable for different types of plant and garden areas. Blue light can keep the distance between internodes shorter and squattier plants, thus better for veg, while red light is a great drive for flowering and better yields.

Therefore, the most suitable spectrum is completely based on your plants’ growing stage, so take this aspect into account before deciding to buy one!

Wattage draw

Wattage is the distinctive characteristic of different types of LED grow lights, determining the maximum amount of light and energy emitted. This figure is also used to check a fixture’s potential for growth.

In general, grow light’s wattage can range from 100W to up to 1000W; sometimes, this figure can go lower or higher, depending on each LED light type. The higher the wattage is, the more powerful the light becomes, and the more cost-effective the electrical usage will be.

For this reason, most commercial gardeners are likely to opt for a LED light with a higher wattage figure to have a better yield and reduce electricity cost.

Coverage area

Here, we are talking about the area that your LED lights can reach and emit light and heat; therefore, it would be much better and more precise if you made a rough guess about your garden’s area before looking for a LED grow light.

Commonly, most large lights can cover a 4 x 4” for flowers and plants while the biggest ones are responsible for a 5′ x 5′ area. If you fail to choose a suitable light to cover up all the areas, we are sorry to announce that you are running the risk of receiving an unproductive crop.

Thus, before all, a full understanding of your garden will ensure you optimum coverage and cost-efficiency.

Light duration

An optimum and healthy growth requires up to 14 to 18 hours of daily lighting and 6 hours of resting in the darkness. Unfortunately, allowing these two phases to occur naturally and effectively is such an uphill struggle, as the day and night switch is unpredictable and dependent on each season.

That’s why LED grow lights play their parts, as they can be a smart automatic timer, useful and time-saving. Instead of requiring daily manual turning on and off, with a LED grow light, what you have to do is to set up a fixed time and let it do the rest.

However, each light will show a different light duration capacity; therefore, check this figure on the label carefully to see whether it suits your plant’s development or not.

Price

High quality comes with a high price, thus, the LED grow lights’ price can be a big consideration to some customers, especially those on a tight budget. However, as each type of grow lights with varied working capacity comes at a different price.

For example, if you are working on a small-scale garden and don’t want to spend a fortune on those lights, you should consider all the aspects of light intensity, spectrum, and quality to choose a reasonably priced product.

On the other hand, if you own a commercial garden and put your effort into those plants, don’t hesitate to purchase the best LED grow lights, as they can last up to 10 years with excellent working performances. In the long run, the benefits are sure to overwhelm the drawbacks.
