COB LED Grow Light vs Normal LED Grow Light
Full spectrum led grow light have itself only recently become a standard in the community, thanks to lower prices and their longevity. LEDs mimic natural light and provide a full, balanced spectrum of red, blue and green. They are composed of light-emitting diodes, their design features help make them more energy-efficient and longer-lasting, and often they are equipped with cooling systems, which improve brightness and longevity by keeping temperatures low.
A new technology for LED grow lights is stepping forward, increasing in popularity, and may soon become the industry standard. This technology is called COB, or “chips on board.” Let’s go ahead and take the time to learn a little more about it.
WHAT ARE COB LED GROW LIGHTS?
A COB LED GROW LIGHTS (short for Chip-on-Board), is an LED packaging technology that describes mounting multiple LED chips directly onto a substrate to form a single module. Multiple LEDs, minuscule in size, are wired and packaged together into a single ceramic or copper board so that they function as a sole light source.

When a COB LED package is energized, it appears more like a lighting panel than multiple individual lights as usually the case with other LED packages, like when using several SMD LEDs mounted closely together.

The biggest difference between COB LEDs and regular LED panels is the architecture: COBs are wired and packaged into a single module so that they function as a single lighting source. By bonding the chips directly into the circuit board, extraneous components are avoided to maximize the LEDs potential.

Advantages Of COB LED Chips
Higher light density: many small diodes in a tight space makes for a much higher light density, meaning you need less space to produce more light
Great spectrum for humans: the white light means your plants look basically the same as they would under sunlight; no more pinkish or purplish glow that hides issues until its too late
Better light spread: since COBs are usually placed fairly far apart on large fixtures, they cover the plants below more evenly than a smaller light fixture that has to spread out from a central point
Efficiency: COBs give you more power per input watt and also product less heat
Disadvantages Of COB LED Chips
There are not many disadvantages when compared to SMD LED lights. If you prefer a light made up of mostly red and blue diodes, then COBs would not work for you.
As of now COBs are only available in come colors and the only ones that work well for growing are the white ones or the pink ones, with white being by far the most popular.
Remember that COB LEDs are still LEDs, they’re basically the same technology in a different package. So there isn’t much to compare other than light distribution.
While COB LEDS do provide an excellent light intensity, they’re not exactly the best when it comes to spread, because COB highest yielding led grow light are a single-point light source (meaning all light comes from a single point in space). If we remember that light drops significantly the further away you’re from the source we can see how it’s easy to leave a few “dark” spots when using COB LEDs. This is why manufacturers spend a lot of time designing their lamps figuring out the best spacing for the most even light distribution over the canopy.
Best COB LEDs to Buy
COB led grow lights samsung-GS Series

Eco Farm definitely has something going on and an option for every need. Their pricing beats a purchasing a Ceramic Metal Halide best commercial led grow lights while adding all the benefits of switching to using COB LEDs, like the improved spectrum, less heat and increased efficiency.
While their design is rather simple they offer a very powerful and useful grow light. This is affordable power.
Full Spectrum and High Lumens Light: Compared with the ordinary indoor plant grow light with only red and blue light, the light emitted by it has the wavelength of 380nm-780nm and contains all kinds of light needed for plant growth, promote faster growth.
CREE COB LED Design: The CREE COB led grow light is grouped by one big CREE LED 3590 in centre/ some small red and blue CREE LEDs 460/630 and OSRAM 660.
Fanless Design Grow Light for Indoor Growing :To keep silence this light uses fin heat sink and no fan system.It doesn't has any noise anywhere.You can even hear the sound of flies flying and you can’t hear any noise while it is working.
