Why would somebody need an LED light when we have a fully functioning Sun? This question might arise in your mind too.
However, everyone is not living the same life. Some people do not get to see the sun for a long time because of the weather conditions in their area. Likewise, some people are too busy with their jobs that they cannot pay attention to the time to take care of plants.

When it comes to indoor plants, it is not suitable to keep them in the dark for a longer time. Similarly, you cannot keep them under the sun for a long time too. Moderation is the key here.
However, if you do not have enough time, you can simply use LED lights. No need to move the flower pot and no need to worry if you have cloudy weather for too long.

How to Choose the Best Color of LED Grow Light

What's the best colour of LED grow light for indoor marijuana plants? Trick question - the best colour is all of them! While your plants may still grow under single-colour or narrow-spectrum lights, they will always grow best under full-spectrum LED lights, which replicate the full range of colours and waves found in natural sunlight. For the very best results for your indoor grow, choose a full spectrum LED grow light.

How do Full Spectrum LED Grow Lights Work?

Full-spectrum grow lights provide the full range of light that your plants need to photosynthesize. As you may remember from science class, photosynthesis is how plants receive the majority of the food they need to thrive. Full-spectrum LED grow lights work by replicating the same sunlight conditions found in the natural world - giving your plants exactly the kind of light they need.

ECO Farm DBL5000 Full Spectrum LED Grow Light 480W

Features:
With 1296 pcs SAMSUNG LM281B diodes, this ECO Farm LED grow light draws 480 watts achieving an impressive PPE of 2.5 umol/J and 6 passive-cooled led bars, higher light intensity, less light decay, better lumens and PAR values than ordinary LED chips. Max 2.5g yield per watt with 30% higher average PPFD and 50% greater yield & quality compared with the old plant lights. The intensity of light can be adjusted according to the needs of the plants. The lighting intensity can be freely adjusted, with dimming options ranging from 0 to 10, for the plants' need of growth at different stages. 6 passive-cooled bars and aluminum heat-sink, etachable external driver and dimmer, not only does it help to reduce the pressure on the lamp body, but also reduce heat inside the grow area. The light board adopts sealing technology so the whole plant grow light is water-resistant - no need to worry about the humid planting environment that would damage other plant lights.

PhotonTek X 465W PRO LED

Features:
This PhotonTek LED grow light is designed with both vegetative and flowering growth periods in mind and the LED may be dimmed, allowing you to adjust PPFD levels produced without losing efficiency.

This dynamic, highly efficient and low powered LED fixture configuration, with five 93W LED bars reduces the temperature of the LEDs increasing the output and improving light maintenance. By perfectly balancing a high quality, full spectrum light with highest intensity PPFD delivered through a multi-bar, Linear design. Producing a total PPF output of 1256 µmol/s and a Photon Efficacy (fixture efficiency) of 2.7 µmol/J, X 465W Pro LED creates a homogeneous light spread at close distance from the crop canopy, resulting in outstanding results when used in indoor multi-layer cultivation systems, grow rooms and tents.

LED Grow Lights: Explaining the Technologies Behind

Illumination is an interesting hallmark of technology. Before the digital revolution, people often demarked the "modern" world from the "ancient" world via the presence of artificial light. It still sounds surreal to realize that electric lights are well over a century old. Of course, the early devices were a hellish nightmare in actuality. Edison's first bulb had a vacuum. The filament oscillating in a vacuum, where heat energy couldn't be conducted, resulted in x-ray emissions to shed the energy.

Neon, or more accurately, fluorescent options are almost as old as bulbs. Tesla famously invented them while working with Edison, and was one of the two disagreements that split them up ultimately.

LEDs, conversely, are somewhat newer. They've existed since the 1960s (arguably 50s) but had minimal practical uses until multiple colours of them at a small enough size, became affordable.

I gave you this brief glance at lighting for a reason - what's happening to light now is very interesting.

LEDs are such a powerful and effective innovation, that they're reshaping our world. We're moving into a period of tech history where we illuminate our homes and devices, and display our graphics all with the same technology, with the scale being the only real difference across them.

In the near future, they will be able to produce LEDs as small as a human cell. This will result in flexible displays, woven-in lighting for clothing, exterior coating that can render images, and much more. Backlights will not be needed as the pixels will be luminous.

Currently, though, another implementation of LEDs is quite fascinating and has a lot of potentials. The big struggle with LEDs hasn't been the miniaturization - once the LED type was designed, making small versions wasn't too big a deal, comparatively speaking. It's always been about the light they can emit. It wasn't until the 1990s that blue LEDs were finally figured out (thus opening up their use for displays). Other wavelengths have proven easier or more elusive.

Infrared turned out to be easy and is used to this day for a lot of remote controls, pulses of infrared light being sensed by the device. This is gradually being phased out by Bluetooth and other high-end wireless technologies.

Ultraviolet, however, has been a struggle. Today, full-spectrum LEDs can produce infrared, visible, and ultraviolet light. Being a powerful wavelength, getting LEDs to emit strong UV is an accomplishment of note. But, what's more, interesting with these, is the practical applications that this technology can allow.

Presently, sun lamps require special bulbs that emit UV, a critical component that makes sunlight as powerful and necessary as it is. Plants require UV rich light to grow, and humans need some exposure to it for health.

With lighting panels that can emit UV and visible light, literally, any light source could potentially be a source of controlled "sunlight". For the far-flung future, imagine what this could do for the space program? For now, this has immediate ramifications for agriculture.

Buying guide

When buying your LED light for indoor plants, pay attention to these features.

Light intensity
The intensity of the lightning will determine the growth of your plants. Therefore, it is better to choose the one that allows you to change the intensity. It will make it useful for a number of different plants.

Coverage
The more the better? Well, it is true here and especially if you have a number of plants. Apart from the number of plants, the area is still important. What if the light only covers half of a plant? It will show irregular growth. Therefore, the light should cover the entire plant so that it can have uniform growth.

Efficient performance and reliable
You are spending quite a sum of money on buying an LED light. They are not inexpensive, therefore, you should choose reliability. If you have bought one, it should work well for a longer time.

Conclusion

Knowing how to use a grow light is the most concerning aspect for plants proper growth. Do not place it too close to them, because the heat can kill the plants and shouldn't be too far, for even spread the ray of light.

Have a happy growing!
