Have you ever been able to hear about COB LED grow lights and what can they do? Well, most people nowadays are not familiar with the concept of COB LED lights and their benefits, but, we are here to provide some explanations and guidelines for anyone who would like to know more about COB LED lights.

What Is A COB LED?
The word COB is actually short of Chip-on-Board and the COB LED lights are specially designed lights with LED chips that are mounted directly into a substrate in order to form a single module. Since multiple LEDs are wired and put all together, they basically form one light source.

Therefore, when a COB LED is powered by electricity, it appears to be more like a lighting panel and not as multiple individual lights. That is the main difference between COB LED lights and other LED packages.

How COBs are better for Indoor Plants Cultivation?

One vital element for your plants includes light quality with essential bands, a well-balanced environment in grow space, regular watering, and fertilizers for nutritional benefits.

Many of the more modern and high-quality COB LED lights have white wavelengths in their spectrum. The white spectrum is made up of green, yellow, and orange wavelengths.

Studies have found that adding white spectrum to Red and Blue wavelengths increased growth in tomato plants by 12–16%.¹ So COB LEDs produce a comparatively better light spectrum compared to normal LED grow lights.

The design of the diodes being closer together enables the output to be more powerful and more energy-efficient. Many COB LED grow lights also include an intensifying lens that greatly increases PPFD readings.

Regular LED grow lights can't use these because the LEDs are scattered around compared to bunched together.

ECO Farm 325W LED GROW LIGHTS

Features:
The ECO Farm LED COB Grow Light is based on 3pcs 80W integrated and 64pcs 5W high power LED as a light source. COB white light can completely replace the cree 3590 spectrum, and provide nutritional spectra such as IR and UV, which can meet all plant's growth needs. The COB channel we have 3000k and 5000k is optional, or a mixture of two color temperature sources. Although each color temperature is sufficient to grow in all growth stages, 3000K is considered to be more conducive to the flowering stage. Centralized COB improves the uniformity and luminous efficiency of the growth panel. As we all know, luminous efficiency and spectral uniformity are the main factors that promote plant growth and health during vegetation and flowering. Each switch controls the on/off of the light, and the three dimmers respectively adjust the intensity of the integrated COB and all 5w LEDs, thereby saving electricity bills.

King COB 360 Watt COB LED Grow Light

Features:
The King COB grow light uses chip-on-board technology (COB diodes) which offers decreased heat generation and increased lumen output when compared with a traditional LED. The King COB 360 watt grow light has 6 moveable light bars which can be adjusted to provide the best level of coverage for your plant setup. Each 60 watt light bar contains 6 x COB diodes, with an impressive 6-watt chip contained in each individual diode; this enables each bar to produce 3000K light that is beamed directly onto your plants. King COB high coverage LED grow lights use a 3000K wavelength that sits comfortably in the middle of the spectrum; sufficiently cool to allow maximum growth when plants are in the vegging stage but situated near enough to the warm spectrum to help your plants flower at the optimum time.

Advantages of Cob Led for the plant growing

The Heat - The COB LED grow lights are not producing almost any heat and therefore, they don't damage the plants. Other light systems are actually pretty much hot when they are on for more than one hour. But, with the COB LED grow lights that are not the case. You can literally touch them and nothing will happen. Also, since there will be no burning of the filament, COB LED grow lights are definitely the best solution and recommendable choice for plants growth. You can put LED lights 30–45 cm above the plants and they will work wonders.

The Color Spectrums - Since all of the light spectrums are required to grow a healthy plant, COB LED grow lights are here to provide that. We all know that the light spectrum that plant requires goes from blue to red, therefore, COB LED grow lights are delivering something in between that, a mixture of blue and red, which is almost perfect for plants growth. If you want your plant to be healthy and to grow big, it is highly recommendable to get the COB LED grow lights, since you can't go wrong with them.

Durability - The COB LED grow lights are pretty durable and they last for a longer period of time than regular lights. This is because of the special design and quality of the materials that they are made of. Anyhow, COB LED grow lights are able to last more than 55.000 hours, which makes them pretty long-lasting. With this much lifetime, you won't need any substitutes or secondary lights for your healthy plant's growth.

COB LED Lights Are Electrically Efficient

First of all, when you use light methods for growing purposes, you tend to get the best light for your plants. Therefore, COB LED lights provide a better amount of photosynthetic active photons that plants need for their growth. Simply speaking, with COB LED lights, your plants will grow faster, and definitely, they will be healthier.

Better Lifespan

It is known that LED lights have a longer lifespan than regular lights, but, with the COB LED lights technology, you can expect your light bulb to be even more durable and long-lasting. It might be a little bit expensive at the start since COB LED lights require a high initial investment, but after a while, you will be benefiting a lot from them. Simply put, with COB LED lights, you won't have to worry about their lifespan.

Improved Quality Of The Light

Possibly the main reason why COB LED grow lights made it to the top of the quality charts so fast is the fact that they provide HIGH color rendering index and broad-spectrum. The Color Rendering Index describes the change of the light's color when it interacts with the object. Simply speaking, the higher the CRI, thing will look more realistic for sure.

Disadvantages of COB LED Grow Lights:

The only downside to COB LED grow lights is the somewhat higher cost compared to standard LED grow lights.

Factors to Consider When Buying a COB LED Grow Light
Stay away from the lowest price lights - they're often the weakest intensity of light.

Look for the real quality and capability of a panel, mainly via PPFD reading.

Consider light intensity, not HPS replacement numbers.

Conclusion

In the light of everything we said above, we can only add that every one of the two COB LED lights that we discussed is definitely worth the money and you can benefit a lot from them. If you plan on growing a plant, then having one of these lamps will definitely help. They all provide great treatment for the plants and they are all equally convenient for indoor use. With any complicated effort or troubles, you will be able to benefit a lot from the lamps that we discussed. Choose your favorite and get it now!
