Chip On Board LED technology, better known by the acronym ‘COB’, have made their way in the ascendancy to the top of artificial grow light technology. Surpassing both prior stages of LEDs and tried and true industry standards to provide a highly efficient, reliable, long lasting and an overall optimized growing opportunity for those willing to try them out, it’s now easy to see what all the ever growing talk about ‘COB’s’ is all about! Voices all over are touting the high praises of these little chips that capture a sampling of our solar sun and bring it down to terra firma, allowing people at will to utilize its advanced power to illuminate darkened spaces and transforming them into lush and vibrant gardens! Such gardens become an oasis for the providing of foods and medicine in abundance for the nourishment and healing to all those who would reach out and freely partake!

As current LED technology rapidly grows at an ever expanding immensity of speed, what was once a novelty, a ‘new thing’ or reserved for the big boys or the ’trial testers/runners’, now with magnetic like precision is grabbing people’s attention to pay attention and not to miss out! Times change, the get ‘on board or you’re going to miss the train’ is applicable to many things in our 21st century. That which was the talk on everyone’s lips, or through the typing of everyone’s fingertips, is always moved aside and surpassed by that which is NOW – the ‘newer and better’. COB LEDs are at the very front of this growth and expansion of lighting technology!!

Before the highly advanced COB style LEDs, or even LEDs in their initial phases used in personal cultivation, many were the winding paths within the realm of grow lights.

Through the progression of the very beginnings of soil stained sunny window sills, to flickering T12’s, all up to the almost war-like cries of those who shout ‘Hail (Metal) Halides’, to the ‘Hail HPS’ crew, the MH/HPS seemed to be the end all of indoor lighting when it came to providing a viable source capable of bringing a seed to an abundant harvest. One would eventually see the shift from the actual light source (bulb advancements) to things more like reflectors (certainly an important field of study and development) garnering the attention and subject of thought for the improvement and maximization of crop yields. The testing of various reflective materials, angles of light refraction, etc. were for a while the ‘new thing.’

MH and HPS lights, for many people, are either too big or bulky, or most often opined against as to the heat concerns for those who grow in smaller spaces. The hassle of having to add ‘one more thing’ (a cooling system in this case), is just another hurdle to cross or just downright cost prohibitive for the penny pinchers already. Loud fans not even mentioned- COB LEDs are beyond question superior in the area of controlling heat output (and reduction of operational noise). COB is LEADING the way in performance and ease of operation in smaller to the largest of grows!

T5’s, T8’s, and even T12’s will likely always be a main stay (until LED prices drop) for vegetative growth, especially for the individual smaller or residential option for startups. LED tubes which fit the standard ‘shop light’ fixtures surpass the traditional gaseous fluorescent’s, so having an incredible high quality COB light fixture dialed in for a smaller space dedicated to vegetative or even vegetative/flower production with excellent spectrum is most certainly the greatest option to implement! The supremacy of COB's to ‘T’ whatever' lights, isn’t EVEN an issue!

What’s old (fluoro’s) was then new again with the popularization of CFL’s! Seemingly a breath of fresh air! Those who wanted to grow in smaller spaces with a lesser productive cost than HID options rejoiced! Still used to this day in particular residential operations, and in the right situations, they are a tried-and-true light source. Overall however, with their slouching qualities and most often less than advertised life span, many were left disappointed and dismayed- not yet finding that Holy Grail. With the proliferation of LEDs, CFL’s are simply outdated to even being not the safest of options- especially with the gigantic fixtures like the 240watt bulbs. LED lighting, in particular the COB style, have taken and delivered on the characteristics promoted by CFL’s, but which came up short in the end. COB style lights being applicable to smaller spaces, drastically reduced operational cost due to high efficiency, reduced heat output, and extensive life span- COB LEDs have the SUPREME advantage over CFL’s for certain!

What seems to be an almost common theme of triplicate acronyms (CFL, HPS, HID, to even (now) LEPs, LECs, etc… sorry MH!) new whispering's began to emerge about LEDs.

The initial scoffers who chided about ‘Light Bright’ toy lights that can’t grow plants began to take notice as the technology rapidly progressed and more and more people were claiming either excellent potential or actual substantial success with even the original ‘stone age’ style technology (compared to the COB’s of today!) of ‘star’ style LEDs. The main drawback was price (to a great degree, sadly, STILL is), but also an abundance of cheap or poor quality products from an array of producers with wild claims/little backing proof to substantiate their claims. Hucksters and ‘snake oil salesmen’ antics turned many off! Many jumped on the DIY wagon however and have never looked back! Those who may want to go the DIY route, still may choose to go with a pre-fab light to get their bearings down with some experience under their belt before getting in over their head, or even running into complications which may turn them off towards LED’s in general, or add them to the ‘slander camp’ which still banters against LED’s (even after years of grow outs, tests and results made public). The clarion call is sounding forth, and is so far beyond now any real dispute- with things like the advancing COB technology (and may it continue to advance!), LEDs are ALREADY the way of the future NOW present!

Current generation COB’s as well also far surpass both the 3 and 5 watt ‘dinosaur’ generation/outdated LED chips/stars. Longevity is certainly a major contributing factor that weighs heavily on the scales towards choosing a COB style LED as opposed to the more traditional HID options- the constant replacement of bulbs adds up. While LEDs (currently) usually have a higher startup cost, as times progresses through successive growing periods, the pricing not only quickly evens out, but ultimately saves over the long term due to the aforementioned lifespan and overall efficiency.

All lighting technologies still have their usage today, but specific COB style LEDs are being made known to have advantages in ALL areas of growth for either the individual resident to large scale grows. The beginnings of vegetative growth to flowering, the full spectrum of COB’s is highly praised as the leading edge, and now exclaimed by many as their be-all and end-all preference. Full spectrum ‘White’ light LEDs are primarily at the forefront of the forefront of COB’s it seems right now, and are surely posed to greatly advance (hope so)! Times ahead are exciting!

What is NOT to love? High output of full spectrum lighting, cost savings in the long run, longevity of life, extensive reduction of heat without added cooling/fan systems, etc…etc.. Viva la COB's!
-----------------
In my own current living condition, a high quality light source is a dream. To possess a LED option (certainly COB style) light for either beginning to end crop production, or initial startup to transplant outside when the sun blazes bright and warm above, would be most awesome! Not being able to work at all (med. issues, gastrointestinal for one (I grow ‘superhot’ peppers as my ‘medicine’) -no Gov. assistance yet, even moving back in with my ‘old man’- money is almost/practically non-existent. Desiring to have at least one 2x4 tent (3x4 or 4x4 would be better, and two of them would be choice, plus having something smaller dedicated to veg would be ideal!) Individual shop light T8’s (not even the large multi 6-8 lamp fixtures), flimsy pvc framed/white poster board (hopefully panda film) covered ‘tents’ and other things less than ideal are seemingly the only option. Indoor growing is really the BEST option (apartment balcony = no space, plus insane 110+ degree heat in summer is no way to grow anything, especially when needed constantly to use as meds. Total failure with outdoor grow last year- hellish heat!) COB’s being the ideal for such an indoor grow, be they multiple pre-fabs, or DIY customized versions, cost is still utterly prohibitive! From all I’ve seen and read, I’m ALREADY on the LED bandwagon (and COB’s the preferred LEDs). To dream of lush vegetative growth, poddage filled tents supplying beautiful medicine of the highest quality year round, such are my happy thoughts… but imaginings don’t bring health maintenance and ease of sufferings! Cheers!

Operating costs $0.05/hr on left $0.11/hr on right.
Not including additional energy requirements of fan/ventilation on right due to higher heat output of HPS lamps.

Grow on the left side stays much cooler. Higher risk of hot spots on right (HPS provides uneven light spread and poor light mixing/spectrums) and lower risk of hot spots on left (COB chips provide an even spread with best light mixing and optimized spectrums).

PS: Left side may last 10 years with no replacements needed and right side will require a new bulb every 5-7 months ($40-$70 depending on where you get it from).

When we saw these pictures we thought to ourselves, man... If companies selling anything other than chip on board LED grow lights saw this they would freak out. Of course they don't want the public to know... They would be out of business! That is scary for many considering how quickly things are changing in the cannabis industry.

"We estimate that the U.S. cannabis consumer market for legalized recreational and medicinal use was $4.4 billion in 2015
and will grow to $9.5 billion in 2019. Once legalized federally,
we estimate this market will grow to $37 billion within 5 years
and $50 billion within 10 years." - New Cannabis Ventures

Still not convinced? You will never know until you try.

Cost is usually one of the biggest factors when it comes to picking an LED grow light for both new and experienced growers. 

COB (chip on board) is more advanced technology than 3W and 5W LED arrays. COB LED chips features higher heat dissipation, lower operating temperatures, and longer lifespan (50,000 hours on the Growthstar models), which equates to increased efficiency. Chip on board and multiple chip on board led grow lights have the lowest light loss which is one of the key reasons why those who have tried other grow lights about to give up on LED decide to stay once they try the Growthstar models. Over 95% of the light remains after one year!

Buying "cheaper" is a myth because most cheaper models will end up costing more when discovering that the power output has been reduced after some use. The major advantage of LED lights over HPS, CFL, HID, metal hallide, or other magical grow light terminology is that the return on investment doesn't happen until 6 months to a year of use. As LED evolves, we expect the ROI to be much less. If the grow light that you bought for a few hundred dollars is known to lose more than 10%-50% of its light output in a year then it would have been better to pay a bit more for a better light and also have reaped the additional features. These are things often overlooked when 'investing' in LED. 

The problem with 3W and 5W LED chips featured on lower quality (cheaper to produce) grow lights is that they offer poor heat dissipation, have a higher working temperature, cause heavy wear and tear on the chips, and consequently have a shorter lifespan. The majority of 3W LED lights found on Amazon or Ebay will work as advertised for a short period and only face a light loss of 5-7% after one year for 3W. 5W LED chips on the other hand tend to suffer a much larger light loss (30% loss!) in 6 months and 50% after one year due to the heavy wear and tear! How come they don't advertise that fact? 

COB chips (superior to the other two) offer a uniform spread of different spectrums. 3W chips will provide roughly 30% less of the 'full' spectrum that is offered by COB chips. 5W LEDs are generally regarded as the least efficient of the three with about 50% of the spectrum not being absorbed due to a poor blend of spectrums. We recommend chip on board LEDs for the best grow results and ROI and generally see 5W chips as having the worst grow results of the three. This doesn't mean you can't get results with 5W LED arrays - it just means you can switch to COB and see improvements in both the short-run and long-run. 

MCOB and COB LED Grow Lights

One of the top performing yet underutilized forms of indoor LED in 2015 was the 'Multiple Chips On Board (MCOB) High-powered grow light. Specifically designed for indoor cultivation, the LED semiconductor chips are tightly packed and run at the highest possible currents.

The benefits includes greater flexibility in design, increased spectrum distribution, improved management of thermal energy, and decreased costs associated with modular manufacturing method (such as reduced customization requirements).

multiple chip on board

Grow lights with MCOB LEDs look different than your typical 3W and 5W grow light. See here in the image below for example. The different colors indicate individual LEDs in different spectrum ratios.

A group of a few dozen of these tiny LEDs form an MCOB grow light. Because the light comes from a small area, the spectrum blends are drastically improved over antiquated grow lighting technology.

mcob grow light - cob grow light

LED grow lights such as the MCOB and COB series grow lights are often compared with HPS and HID grow light sources. While both sides have their backers, there have not been enough studies to conclude whether one way is better than the other. Some growers do however claim (in individual testing) that they've experienced greater energy efficiency and reduced heat output using COB and MCOB grow lights. This should come as good news to any grower that is unhappy with their current energy bills. Switching to MCOB or COB often means paying a fraction of the cost of other top selling 3W and 5W arrays.

plants vs human eye

While plant biology is not something we all understand, it is important to remember that plants react differently to light spectrums than humans. What you and I perceive as light (based on brightness) may not look as bright to a plant. Plants do not absorb all spectrums. In fact, green, yellow, and a few others only make up a small percentage of light absorbed. Many indoor cultivators commonly believe that if plants look bright under HID (high intensity discharge), HPS (high pressure sodium), or Metal Halide bulbs and lamps, that the plants are getting lots of light. This is simply not the case. Plants require a variety of spectrums including UV and IR to achieve maximum efficiency and health.

COB grow lights generally consist of white light as far as LED technology goes. COB, which stands for Chip On Board, makes an excellent light source for residential and commercial lighting projects. Using Blue 440nm LEDs and phosphor coating for color correction, it produces a spectrum blend that has been adapted into our latest Scorpion Grow light series. While white lights found in COB grow lights are well-suited for producing vegetables, plants, and other crops. the MCOB grow light is well-suited for growing any kind of plant. This includes different strains, and stages be it vegetative or flowering.

Growers shouldn't limit themselves to just purple, red, or blue LED grow lights found in previous products. What might work for growing lettuce is not the best option for growing other types of plants. This is more important when growing on a large commercial scale as the little things add up. In those cases, MCOB LED grow lights which blend 9 types of spectrums per MCOB chip is a more efficient option. The special blends of pink/blue (purple) light found on MCOB chips gives almost all plants the light they can utilize to a high degree.

Just Purple isn’t good enough, previous generations of LED Grow lights used combinations of red and blue, producing a purple blend that is adequate for growing lettuces but MCOB blends 9 different spectrum on a single MCOB Chip, recreating an exact blend of purplish light, high feeding plants love.
