Best 600W COB Grow Light (Updated 2021)
The most recent craze among indoor growers is the COB LED grow light. COB, which stands for chip on board, is a technology that allows for many LED chips to be placed on one lighting unit. COB lights consume less power, are brighter, and have a higher light output than older LED lights using technologies like SMD and DIP.
COB LED grow lights have replaced traditional MH and HPS grow lights which operate at a high temperature and have a high energy consumption.
As indoor growers, there’s one thing we know for sure: the healthy development of plants is highly dependent on light. COB LED grow lights provide the best illumination for plants to bloom and produce high yields.
Differences between LED and COB lights
There are many differences between both types of lights. Both of them come with similar features. Some of the things they have in common include impressive durability, efficient light output, and a wide spectrum. However, the differences are what really matter. Lumen Intensity As I said earlier, the COB model has more LEDs cramped on the circuit. The result is that you get more light. The lumen intensity of the COB is higher than that on an SMD or surface-mounted device. It also gives you more even lighting. Focus Using a reflector design and having a larger number of lights fixed on a circuit board, COBs give more focused light than SMD. It is denser and with a reflector, the light is even brighter and evenly spread, which your plants would love. Size COB lights use space more efficiently than your typical LED light. You can arrange a 100 lumen COB array tighter than a 100 lumen SMD array. This results in smaller products, which is what you might need on a small indoor farm. Heat The more the components in an LED fixture, the more the heat produced. That is why COBs do not produce as much heat as you’d expect. It simply has fewer components that can get hot. They also come with a thermal sink that is directed toward the board. While COBs are generally less hot, when choosing a COB, check out the type of heat sink it uses. You should also consider the design of the board and the material of the COB substrate.
Benefits of Using COB LED Lights
1. The spectrum COB LED Grow Lights provide is large and temperature ranges are vast.
2. The COB LED Grow Lights are more cost-effective as they produce much more power per input watt.
3. They require very little space for installation and have wide coverage.
COB LED Grow Lights are very bright hence safety glasses should be used under them.
Features:
ECO Farm COB LED grow lights can help you grow indoor plants almost effortlessly. The concentration of red and blue light in a broad spectrum (purple light) helps plants grow and bloom. You may even notice that your plant grows taller, but this may be because it lacks some blue light. The necessary fans keep the lights cool. Channel dimming controls power output and pixel ratio. The combination of VEG and Bloom and COB is ideal for specific plants. We have optional COB channels of 3000k and 5000k, or a mixed source of two color temperature sources. LEDs help spread light, but you may notice some light loss in the space between these lights. The service life of these lamps is approximately 50,000 hours. If you use these lamps for 18 hours a day, it is equivalent to approximately 7 years or more. If the light burns out prematurely, or the fan or drive stops working, the good news is that you have a two-year warranty to replace it.
Niello 600W LED Cob Grow Light
Features:
The spectrum range is about 380–780 mm. This, along with the cleverly angled lenses ensures a high PAR value and allows better growth of your plants. The COB technology used ensures you to save 30% of the energy costs and allows for a dustproof operation. Moreover, this grow light produces highly intense and bright red light which is ideal for boosting the process of photosynthesis in your indoor growing cannabis plants. To maximize effect of light produced from COBs Niello has equipped this LED grow light with scientifically designed and advanced reflector cups along with an optical lens cover. Now, for people seeking information on the coverage potential of Niello COB LED Grow Light, we’re glad to mention that it’s well suitable for an area of up to 2.5′ X 2.5′ if you hang it at 18″ height. For cooling and better heat dissipation, there are 3 small-sized and quietly operating cooling fans on the backside. Moreover, it’s an open-ended design so heat dissipation takes place from the side sink.
Morsen 600W Cob Led Grow Light
Features:
There are several reasons why Morsen COB LED lights are popular and well-received. There are many types of other lamps, but this type of lamp in particular is one of the most energy-efficient options. Bright, strong lights provide a wide spectrum, but it’s easy to go green, so you give your plants a green screen. You can also get 600 watts of power, and the energy used requires 96 watts. Most COB LED plants grow but include light machines. Fans, but many of them may generate noise. Those on this machine are quiet and can lower the temperature well.

You can turn on both lights at the same time, or you can turn them off. Or on the other side, this will reduce the intensity when you simulate sunlight plants.
Buying Guide for COB LED Grow Lights
When deciding which COB LED grow light to buy, there are important factors to consider and questions to ask. This guide will give you clarity and help you to decide which light is best for your specific requirements.
Here’s what to look for.
Full Spectrum
For plants to grow well, they require a particular range of light spectrum. Outdoors, natural light from the sun provides plants with a full spectrum for their growth. Indoors, LED grow lights provide plants with optimum light wavelengths. This optimal range is commonly known as PAR (photosynthetically-active radiation).
This spectrum has wavelengths between 400nm and 720nm. Plants typically use red light (620nm-700nm) and blue light (400nm-500nm) wavelengths in the highest concentrations. For this reason, the performance of COB LED grow lights should be measured in relation to PAR instead of lumens. A handy device called a PAR meter can help you measure the PAR output of your grow light.
The Size of Your Grow Area
If your grow area is 5X5ft, a COB LED grow light with 3X3ft coverage won’t be able to provide sufficient light to your plants. Your plants should be well illuminated by the light in order to grow and flourish.
Ultraviolet (UV) Light
Most grow lights on the market have very few chips with a UV spectrum for valid reasons. A high amount of UV light can be detrimental to the plants, damaging their physiological processes and endangering human beings as well. Most grow lights feature a small amount of UV which is safe for plants. UV light can make plants very potent.
Dimming Feature
COB LED grow lights that are dimmable allow you to adjust the light depending on the growth stage of the plants. As they germinate, the light can be dimmed to minimum to support growth at that stage. Very bright light at this stage can slow down growth and damage plants.
As the plants grow, the light can be increased at each stage because they can tolerate the brightness without any risk of damage to their growth.
Cooling System
All COB LED grow lights feature a cooling system, and rightfully so. But cooling systems are different. Choose a light with an in-built aluminum heat-sink, powerful fans, an air outlet, and an inlet. These keep the light cool and prevent overheating, which could damage it. Also, the atmosphere around the plants remains cool and their growth process is not affected.
Conclusion
The COB LED Grow Lights are produced for commercial greenhouses, indoor grow facilities and research applications. Be sure about the purpose you need it for like the kind of plant cultivated and the photoperiod required.
