Why LED Grow Light Is The Best Choice?

Firstly,we can analyze the characteristic benefits of [url=http://www.twilightgroups.com/product-24-1.html]LED grow lights[/url] in greater detail.

# Specific wavelengths can be targeted

As we noted above, the use of LED technology allows for creation of lights which target certain specific wavelengths rather than provide a broad and often inefficient distribution of light over a large spectrum. Though [url=http://www.twilightgroups.com/product-24-1.html]full spectrum LED grow lights[/url] do exist (and indeed are the most common), wisdom lies in using LEDs which provide the maximum light in the 400 to 500nm (nanometer) and 600 to 700nm regions, which are most preferred by plants for photosynthesis.

Such grow lights will allow the plants to absorb the right amount of light energy at the right time, provided the right LEDs are used during the corresponding part of the growth process. This, apart from benefitting the plants, ensures that there is little wastage of electricity in producing lights which the plants have no use of.

# Excellent lifetime

LED lights produce very little heat and this, coupled with their internal dynamics, ensures a long lifetime of between 50,000 to 100, 000 hours. What this means is that these lights can be used for up to 11 hours continuously, and more practically, for 22 years at half time. Not only is this time frame enough to recover the initial input costs many times over, it also ensures that frequent maintenance (due to dead bulbs or other problems) is not an issue. Given that plants need continuous lighting for long periods of time, frequent maintenance disruptions can have an adverse effect on the overall growth cycle, and this can impact the quality of the output regardless of the availability of other factors.

# Gradual dimming

[url=http://www.twilightgroups.com/product-24-1.html]LED grow lights[/url] gradually fade out, losing luminosity as they near the end of their long lifespan. Of course such fading out reduces the overall efficacy of the light produced, but this also gives the user a forewarning of the approaching demise of the LED bulb. A panel with a number of such gradually dimming bulbs can be replaced ahead of its actual expiry, so as to ensure that the plants don’t have to suffer from “dark days”. This is in marked contrast to the incandescent and HID bulbs, which tend to die out quickly when they reach the end of their lifespan, thus giving the user no time to stock a spare bulb or panel in advance.

# Flexibility of Design

Unlike the other types of grow lights, which are bulky and hence can be arranged in a finite number of arrangements, LED grow lights can be arranged in a wide range of arrays depending on the growing needs of the horticulturist. Indeed, LED strips and even individual LEDs can be taken and combined into structures capable of working together to illuminate unconventional plant grids.

Indeed, some of the most efficient new-age arrangements such as inter-lighting designs between plants and multilayer vertical systems can only be achieved using LED lights.

# Greater energy conversion efficiency

One of the primary concerns of growers regarding HIDs or incandescents is the high amount of heat produced. Heat, as we noted above, can prove detrimental to the lifespan of the plant, and even kill it off. The traditional solution to this has been to keep the lights at a great distance from the plants, but this proves to be a problem due to the operation of the inverse square law (explained below). LED lights, however, produce little to no heat (less than 10% of the heat produced by HPS bulbs of similar wattage) as they convert a large portion of their electricity supply to light energy. This means that the LED lights can be placed in close proximity to the plants, thereby ensuring optimal absorption of light. Coupled with the flexibility of design mentioned above, this proximity has made possible close multi-layered arrays which would have earlier been unthinkable.

# Huge Energy Savings

Energy efficiency converts directly into reduction of electricity costs, and through it, to the lessening of the overhead cost involved in growing plants indoors. Studies have shown that the higher efficiency of the LED lights translates directly into 40% lower electricity costs as compared to HIDs of similar power in a general setting. A more specific study using tomato plants showed a much higher – 75% – saving of electricity as compared to a similar setup using HPS bulbs. As these indicate quite clearly, LED lights are the more pocket friendly solution for small home growers (who do not have economies of scale on their side to cover the huge overhead costs), while offering a more economical option for commercial growers. Last but not least, such energy efficiency reduces the burden on our limited conventional sources of energy and through it, gives impetus to the vision of a sustainable future for human energy needs.

# Now Available In Required Wattage

The earliest iterations of LED grow lights were weak products of just 10 to 20W. However, these days products of 100W or more have appeared, which can successfully challenge the efficacy of older incandescent and HID lights of much higher wattage in terms of luminosity, while saving the user valuable money. This means that grow lights of the LED variety are now applicable in a wide range of indoor horticultural setups, instead of being limited to just the smaller ones. Furthermore, though LEDs with higher wattage produce more heat, the rise is insignificant compared to the rise in heat output noted in case of HIDs.
The “How” and “What” of LED Grow Lights

We mentioned earlier that the LED grow lights are a recent innovation, with the fall in prices of these lights being an even more recent development. Such statements raise the question – “How did these lights emerge?”. Before we can answer this question, we need to see the history of LEDs briefly, and figure out just how they work.
