What is COB LED lighting?

First, not all LED lighting is created the same way. LED stands for light emitting diode. A diode is an electric component which has two terminals. The electric current causes the diode to send off a bright light which surrounds a small bulb. A COB LED light is a little different than a standard LED light. COB stands for chips on board and refers to the fact that this style of light has multiple LED light chips built into one module instead of many individual modules. This gives the appearance of a lighting panel as opposed to individual tiny bulbs.

How to Choose the Best COB LED Grow Lights?

When you are starting out to find the COB LED grow light for your indoor garden, you will want to do a little research and be sure to watch out for some key features or characteristics in the lights you are considering. Once you have taken these suggested features or points in to consideration, you will be able to make an informed decision as to which COB LED grow light will work best in your specific situation.

Full Light Spectrum

Whichever light you decide to use in your space, it should definitely offer full light spectrum technology. This refers to the fact that the light has been color-corrected to perfectly emulate natural sunlight at the highest point of the day (typically noon) and runs between 400 and 800 nanometers. Plants require this full spectrum lighting to flourish and grow to their best potential

Heat Dissipation

While it is true that a COB LED light may output less heat overall, there is still some heat to control. When choosing the right light for you, look to see that the one you select has cooling fans built in to control the heat it is giving off. Ideally, it should have more than one fan built-in and you will want it to operate efficiently and quietly.

Energy Efficiency

Most LED lights are energy savers, as such so will a COB LED grow light. However, if you want to go that extra mile, look for one that has optimal energy saving capability. The packaging should outline how much power is being drawn from the electrical source versus how much energy the light is outputting towards your garden. This will give you the answer of how energy efficient your COB LED light will be.

Daisy Chain Capability

If your indoor garden is larger, or if you foresee that you would like to eventually expand your garden, then you should look for lights that come with daisy chain functions. This means that the light can be connected to other COB LED lights to create a strand of lighting that connects to one electrical outlet instead of having each fixture requiring an electrical connection each. This will save you time and headache down the road.

Assists with Different Stages of Plant Development

In a perfect world, you will want to choose a COB LED grow light that will help your plants grow from seed to full bloom and everything in between. Some lights are equipped with a switch for different plant stages, which is great to get that specialized lighting for your growing crop.

Why Choose COB LED Grow Lights?

Via Amazon.com

You may be wondering why you should choose COB LED lights over traditional ones to help your indoor garden grow. There are many reasons and advantages as to why this style of LED light is a better choice to get you the results you are hoping for.

Low Light Loss

With standard LED lights, they are very bright to the naked eye and if you were to look directly at them, you could damage your eyes. If you add a light lens to reduce this from happening, you will lose valuable light. With a COB LED light, you won’t have this issue. Since the lighting appears as a panel light instead of many light bulbs, the brightness affect on your eyes is not as great and you won’t lose light the same as you would with a standard LED light with a lens.

More Light Output

If you were to compare a standard LED with a COB LED of the same size and shape, you will get a much broader span of area covered by the COB LED light. This is great for indoor gardening since it means you will have to use less lights for your growing crop. You will still get the same amount of lighting with less fixtures.

Reduced Heat Output

The importance of keeping your indoor gardening space is vital to proper growth and to achieve the best results possible. If your indoor gardening space becomes too hot, you need to add fans or a cooling system to reduce the temperature, which then means you are using more electricity. COB LED lights have less heat output than standard LED lights, so you won’t have this issue as often.

More Cost Effective

Your initial investment to purchase the lights may seem quite similar to purchasing other lighting for your indoor garden. However, once you factor into your purchase that these COB LED lights will last longer than most other types and draw less electricity, you will be saving yourself money over the long run. With the rising cost of electricity, you will appreciate the savings on your next bill.

Small but Mighty

Do not judge a COB LED based upon its size. Even the smaller COB lights will output a brighter, dense light span than other LED lights of equal and even bigger size. The use of a single panel style LED light allows for greater brightness output which covers a larger area at the same time.

In Conclusion…

If you are interested in getting started with indoor growing or if you have been growing indoors for some time already, you will want to ensure you are using the best equipment to yield the results you are looking for. This means that you should consider which are the best COB LED grow lights to use for your particular space and how each will affect your plant development.

When it comes time to purchase grow lights, and you have decided on COB LED lights, you should do your homework and look into key features which could adversely affect the outcome of your crops. The size of your garden will dictate how many lights you need and if you do need many lights, you will probably want to consider lights which have a daisy chain connection available to avoid wires getting tangled and creating a mess.

Hopefully you have found this buying guide for the COB LED grow light useful and helpful in finding what is right for your area. You don’t have to break the bank to get great results from your grow lights, just research and investigate the product before purchasing, ensure your lights have full spectrum lighting and get growing!
