LED Grow Lights

LED grow lights are energy efficient, low heat, and are a popular indoor lighting system for both hobby and commercial growers. These lights are available to buy in full spectrum to mimic natural sunlight, or engineered for specific wavelengths to promote different growth cycles. They provide a cost effective solution for healthy plant growth and huge harvests. 

At London Grow, we stock a wide selection of LED grow lamps from all the leading brands including LUMii, Maxbright and Lumatek. Buy LED light bars and strip lights online with fast UK wide delivery, or visit our store in Enfield, North London.

Benefits of LED Grow Lights 

LED grow lights offer many advantages for both professional and amateur growers. Benefits include:

Energy Efficiency
LEDs consume far less energy compared to other more traditional lighting systems such as high intensity discharge (HID) lamps. As a result, growers can reduce electricity costs and increase profit margins.

Low Heat Output 
Unlike other types of grow light such as high pressure sodium lamps, and metal halide lights, LEDs emit very little heat. This reduces the risk of potential heat damage, and also helps to reduce fire risk. Less heat in the grow room also reduces the need for heavy duty cooling and ventilation systems which can help to reduce overall energy consumption.  

Long Service Life
Light emitting diode lights have an impressive service life. Depending on the brand and model, LEDs can last from around 50,000 to 100,000 hours, which is a lot longer than the average lifespan of alternatives such as HPS, MH, and CDM lights.

Full Spectrum or Tailored to Specific Wavelengths
These lights are highly versatile and are available to buy to provide the full lighting spectrum or specific wavelengths to provide extra support for different growth stages.

Eco Friendly
Unlike some other types of lamp, LEDs do not contain toxic materials such as mercury. Their reduced running costs can also help to lower the carbon footprint of your indoor garden.

Sleek Design
Thanks to their sleek design, LED lights can fit into tighter and smaller grow rooms, and your plants can safely grow close to the light.

User Friendly
One distinct advantage of using full spectrum lights is that you do not need to change the lighting system as your plants grow. 

What does LED stand for and how do LED lights work?

LED stands for ‘light emitting diode’. This type of lighting contains a semiconductor device. When an electrical current passes through semiconductors within the diode, light is emitted. 

Do all LED grow lights provide the full light spectra?

No, not all LED grow lights emit full spectrum light. This is because some types of LED lighting are engineered to target specific wavelengths to support different growth stages such as the vegetative or flowering stages. A good example of this is the ROOT!T LED Grow Light.

Full spectrum LEDs mimic all the wavelengths of natural sunlight, from ultraviolet to infrared. For most growers, full spectrum lights provide a user friendly, cost effective option. The Lumatek Zeus is a great example of a high-quality full spectrum grow light with high photosynthetic photon flux (PPF), and photon efficacy. 

Are full spectrum or wavelength specific lights best?

Full spectrum LEDs are very popular for indoor plant cultivation. This is because the full spectrum of wavelengths supports every growth stage from propagation and vegetative, to flowering and fruiting.

However, in some cases, specialised plant species such as certain exotic plants may have very specific requirements and benefit from a boost of wavelengths from a particular section of the light spectrum. For example, some plants might benefit from more blue light during the vegetative stage to promote robust leaf growth and strong stems. Alternatively, some plant species may require more red light to boost flowering and fruiting. 

What are the disadvantages of LED grow lamps?

When LEDs were first introduced to the market, this new technology came with a premium price tag, making them a more expensive option compared to alternatives such as HPS grow lights. However, over the years advances in LED lighting technology have seen production costs fall, resulting in a significant reduction in costs to the end user. As a result, LEDs are now cheaper to buy and are one of the most popular types of grow light on the market.

Another potential disadvantage in older LED lighting was their light intensity and canopy cover. Again, advances over time have closed the gap between HID and LED lamps. 

Extended exposure to bright light and blue light can damage the eyes, and for some, this has been a concern when using LEDs. However, this can be easily overcome by wearing suitable grow room glasses to protect against UV and infrared rays.

Always Buy High-Quality LED Grow Lights

As always, investing in quality grow lights from the get go is a good idea. Although LEDs offer a wide range of benefits, better brands will deliver superior light quality and intensity.
