Are LED COB lights any Better than the typical LEDs?

best cob led grow light

LED lights are some of the newest technology that allows farmers to grow plants indoors, providing some of the best conditions for growth.

COB lights incorporate many tiny LEDs that appear to the ordinary eye as a mass of lights. They are better than the typical LEDs in so many ways. For starters, COBs give out a full scale of white light – there is no purple or red light.

Another thing about COBs is their affordability. In an actual sense, you don’t have to strain your budget to acquire them – there is no logical reason you are stuck on plain LEDs or even hydroponics. They are also energy efficient – even better than LEDs – and so you save on power costs. In fact, COBs use more than half the power that LEDs use. This means that you achieve the same objectives cost-effectively.

Another reason to choose COB is the lifespan which is better than LED. At about 30000 hours, its lifespan is better by more than half of LEDs which is mostly less than 15000 hours.

COBs also have a High Coloring Index (HCI). This HCI determines how light appears before your eyes, and the higher it is the more realistic the perception. In other words, there is no purple, orange, yellow or red but a more robust white light – there are no unrealistic colors.

When it comes to light distribution, COBs have a better performance in comparison to the others. Placing these lights at various locations in the grow room avoids any blind spots typical of HID lights or LED. This means that you achieve more efficiency with them than with any other lights.

Choosing the Best LED

  • Brands: in every market, you can quickly name two or three brands that are consistently top quality. In the world of COB LEDs, three names usually feature – Citizen, Cree, BloomBeast, and Bridgelux. Bridgelux, BloomBeast, and Citizen have the best all-rounders that are kind in your pocket. Cree COBs are energy efficient but require you to loosen up your purse strings. Whichever choice you make, it is always good to go with the trusted brands, as chances of getting frustrated are quite minimal.
  • Color Temperature: this factor is all about the warmth of a particular color when it comes to planting growth. The primary objective of using LEDs is Photosynthetically Active Radiation (PAR). This is the range of light most important to plants for photosynthesis. There is an unending debate regarding which lights are better. For some people, 5000K lights are best for plants in the blooming stage. Others contend that a warmer light in the region of 3000K is much better when the plants are flowering. You will also find others that go the middle way by choosing 3500K, which they think is better in both stages. For simplicity’s sake and to avoid a situation where a group was right all along, you should go with 3000K or 3500K lights for the whole growth stage.
  • Efficacy: this is easily defined as the number of lumens for every watt of power produced by a COB. Even though lumens are not the ideal units of measurement, they are essential when comparing one LED with another. The better the score in terms of the lumens of a particular LED over another, the better it is.
  • The grow space size: it goes without saying that the bigger the space you have for growing plants, the more units you will require for efficiency. A reasonable estimation is in the region of 32 watts per square foot.
  • The Type of Crop: depending on the type of crop you are growing, you can choose one light over another pretty quickly. Most of the LEDs will produce many plants to the flowering stage. Some of them are designed for particular types of plants – not all plants require the same amount of sunlight. If anything, just go with the right kind of lights to avoid regretting your choice in the end.

Conclusion

The best-LED light has the perfect design and is easy to use. It must lead to the maximum yield, and its operation must be flawless. The cob-led lights in this review are pretty decent and would make an excellent choice.
