LED Grow Lights Useful Information Guide” is meant to inform you what some of the very popular misconceptions are in regards to LED Grow Lights and what is factual vs. what sounds good to your general public.

1) The LED wattage is of particular importance as many companies are using the 2W, 3W, 5W, 6W or even higher wattage LEDs and claiming potentially they are more powerful and thus creating a more productive flowering cycle. The fact is that there is no more efficient LED versus High-Intensity 1W 10mm Diode. The reason being is the input vs. output ratio drops off dramatically the more expensive wattage LED that is used, and ways in which you know this to be true is that if you test your light with a voltage meter to find out the actual power consumption of your light. Our 90W UFO with all of 1W Diodes draws between 80-85 watts subject to temperature, where a 90W UFO made up of all 3W Diodes will draw between 55-60 watts of consumption power. The point is that it sounds good to hear a larger wattage LED being used, even so the truth of the matter is that you are actually losing your overall power output by using these inefficient higher-wattage LEDs.

2) The Brand name of the LEDs being used in lights is a popular marketing tool to advertise such brand names as Cree or Bridgelux. The truth is that both Cree and Bridgelux both specialize in producing high Lumen LEDs which can be used for commercial lighting like street lighting or commercial buildings. Horticulture lights are a specialty field and very few manufacturers in the world that produce LEDs which have been appropriate for horticultural purposes.

3) LED Lights which are significantly cheaper than other lights should raise a red flag right away. The truth is that try using a precision LED that is a geniune 10mm (High-Intensity) 1W Diode is expensive, and to get around this cost issue, some companies utilize 5mm diodes, which are significantly less powerful than the 10mm diodes, thus resulting in a poor performance. There are several ways to skimp on the cost of manufacturing a quality LED Grow Light that creates results that are equivalent to HPS lighting, so be wary of low-priced LED Lights that sound too good really.

4) The number of “Bands of Frequencies” used is of significant importance to photosynthetic activity. There are 3 photosynthetic processes that occur; Chlorophyll A, Chlorophyll B & Carotenoids. To address these processes you’d need a minimum of 3 Bands, and bring the full potential of this plants photosynthetic ability, you will need 2 of those Bands to be duplicated in more than on spectral output. This is why we use 5 Bands in the lights, any more would be redundant and done this with an off-peak frequency. Some companies advertise around 10 or 11 Bands, and although this sounds good in theory, in fact it is using the same principles which will make an HPS light only capable of emitting 15% of absorbable light for your plants and this defeats the entire efficiency concept behind the employment of LEDs.

5) Lastly, the option of which company to purchase your LED Grow Light is ultimately your decision and we try to provide you with just as much detailed information as we can that will help you make a more informed decision. To better make sure you are getting what you pay for, make sure the company has been in business for several years and they offer a guarantee of performance and stand behind the product they are selling to everyone. The best way to really determine if you’re buying a quality light is to consult the company and ask questions.

On the subject of purchasing LED grow lights, we whatsoever LED LLC know you have a plethora of choices which is available from many different sellers, all of whom state that their products are the best available. While LED grow lighting is definitely more power-efficient than the old generation of High-Pressure Sodium and Metal Halide bulbs, all of which will considerably lower your electricity bill, all LED grow lamps will not be standardized and do not represent equal performance. There are literally unlimited variables of wavelengths and ratios which might be employed into a light design, plus the LEDs themselves and how they are powered.

ALL LED LLC wants anyone to know these facts before you decide:

Some manufacturers claim that their lamps are the brightest, and give their specifications in lumens. A lumen, however, can be a measure of light which is considering human perception and not an accurate, accurate measure of the photosynthetic power of sunshine at all. Indeed, while their light may seem to be bright to us, may well be bright to plants at all; if the light does not contain all the precision values (wavelengths) plants need to thrive. If a manufacturer advertises their light specifications in lumens, lux or candlepower, beware!

Plants also employ many different bands of light for photosynthesis, as well as some bands of light which, while not photosynthetic to a plant, aid in healthy development, along with flowering. Some of these photosynthetic and non-photosynthetic wavelengths are nearly beyond your human range of perception, , nor seem as bright, while they are nearly equal in capacity to the highly-visible bands. If these bands are neglected in favor of LEDs that appear bright to the eyes, plants will not develop correctly. This is a common complaint with early LED grow lamps that used only one or two different values of LEDs, but many manufacturers still design and provide lamps to these outdated specifications.

Oppositely, some manufacturers advertise a full-spectrum, and frequently include white, green, and yellow LEDs of their design. Many of these wavelengths, however, are inefficiently used by plants, if utilized whatsoever. Plants have three main photosynthetic substances that react best at certain, precise wavelengths of sunshine. When you look at plants in sunlight, most plants appear green, as the bluish-green through yellow-orange spectrum is the spectrum of light which most plants reflect. Reflected light is light which is not used by the plant! To address the usage of white LEDs, almost all of them combine certain amounts of blue, red, and green light to provide what we see as white (visual purpose was the explanation they were manufactured in the first place), but the majority of these white LEDs use wavelengths of those individual colors that are still nearly useless to plants. Full spectrum advertisements SOUND good, but you are wasteful of the light you will need and the electricity you pay for!

LED precision is extremely important! If an LED output is obviously any good fraction off of the plants necessary peak value, it could be extremely inefficient for photosynthetic and non-photosynthetic processes. Some manufacturers use less-expensive LEDs that seem close enough to the numerical peak, when, in reality, their chosen values might call for up to 10 times (or more) several LEDs to do what ONE LED of peak-value efficiency is going to do! ALL LED LLC has scoured the globe to find the EXACT peak values that plants utilize. Only at is close enough for individuals! (And it should be for you too!)

As you shop, you will also notice that some manufacturers advertise actually using 5 and 10 watt LEDs into their products. While these LEDs are incredibly showy and brighter than their 1 and 3 watt counterparts, they are also very power-inefficient. Higher-wattage LEDs create more heat, so much of the electricity they consume goes toward the output of that heat, and the sad the fact is that they do not put out nearly the proportion of light to the power consumed since the 1 and 3 watt LEDs. Depending on LED manufacturing differences, some 5W LEDs release LESS light than the best 3W LEDs! (Also, it needs to be noted that, for the wavelengths of light plants can best use, hardly any of these wavelengths are available in LEDs rated higher than 1 and 3 watts!) Ironically, items which use higher-wattage LEDs to produce identical amount of light as 1W and 3W-based units are also much more costly to manufacture, and therefore cost gets passed down to your account as the consumer many times over: once in the time purchase, and again, anytime you pay your electricity bill!

Lastly, many knockoff imitators manufacture lamps which will look like ours, or might just differ in case color, shape, or style. These sellers say he is just as good or better, however they rely on cheap gimmicks so that you can try to stand out from the rest. (One maker has a black case, and black ABSORBS light!) If you decide to do your research, it will become very clear as to who is for real and those who are just reselling some cheap imported light to use advantage of a very promising industry.
