COB LED Grow Light Review – The Idea Of Growing Plants Indoors


The idea of growing plants indoors was once limited to literal house plants. It was impossible to grow flourishing flowers, vegetables and herbs inside our homes because we didn’t have the resources necessary to mimic outdoor lighting and the elements.

Today we have the technology that is necessary to grow a broad variety of plants with all types of natural lighting needs. This technology that uses light-emitting diodes, also known as LEDs, has actually been around for decades, but we are just now learning how to use this type of light to create amazing indoor gardens that produce healthy and thriving crops.

The latest advancement in indoor plant lighting is the invention of the COB LED Grow Light. These lights produce a wider range of light spectrum and are much more efficient than other LED lights.

COB LED grow lights are fairly new to the industry, but they are already gaining recognition for being the most successful, high-quality plant lights that there are. COB is actually part of an LED light. But these grow lights are different from your standard LED plant lights.

How Does That Work?

LED lights that are used for indoor gardens are made up of various colors designed to mimic natural sunlight. This allows the plants to receive a spectrum of blue and red lights as well as some green or white lights.

COB stands for “chip-on-board” and the technology works by clustering LED lights inside a concentrated area. When a COB LED light is turned on, it will look like a single light. But in reality, it is a series of small lights in a spider web design. These lights are often housed in a ceramic, aluminum, or copper holder, which helps to dissipate the heat generated by all the tiny COB lights.

Most COB LED lights will include a fan that helps to circulate the air inside the heatsink. These fans prolong the life of the LED lights and reduce the amount of heat produced to keep the plants happy and healthy.

How Does a COB LED Grow Light Compare to Other Plant Grow Lights?

If you have attempted to grow plants indoors in the past, you may have used an old-fashioned heat lamp or grow light. If you have tried to grow indoor plants within the past few years, it is likely that you are familiar with some of the current grow light models out there. These include High Intensity Discharge (HID) lights, Fluorescent lights, and LED lights.

High Intensity Discharge Lights

HID lights work well for plants that require a lot of sunlight and those that can withstand a lot of light. These lights are not recommended for use with seedlings as they are too intense for young plants to be exposed to. There are several types of HID lights including metal halide, ceramic metal halide, and high-pressure sodium or HPS.

Most people will agree that HPS lights are the most efficient type. A 600 watt HPS light is capable of producing more light than a 1000 watt HID light. The lifespan of an HID light is around 15,000 hours, depending on the type that you use. They can range between 10,000 and 24,000 hours at the most.

Fluorescent Lights

Fluorescent lights are a popular choice because they are energy efficient. They can last a very long time and cost pennies to run. Tube style fluorescent lights can provide between 30 to 90 lumens per watt. While they do not provide the brightest light, they are great for seedlings or for indoor herb gardens.

The best thing about fluorescent lights is their lifespan. They will typically operate between 10,000 and 20,000 hours based on the type that you use. Fluorescent lights are also some of the best affordable grow lights there are. But they aren’t efficient for all types of plants, which is their primary drawback.

LED Lights

Small LED lights placed in rows can be used as an effective grow light. Each bulb measures between 5w to 1w in power, however, there are some LED lights that are between 3w and 5w each. The higher the wattage for LED lights, the more heat they produce. That is why they are preferred for plants that require plenty of natural heat from the sun to thrive.

How COB LED Lights Compare

A COB LED Grow Light is a cluster of many tiny bulbs that come together to provide one single light source. They can measure as much as 300w, however, because of their unique design, COB lights use less energy, which makes them more energy efficient than LED grow lights, and more powerful.

Reviews of the Best COB LED Grow Lights

When you compare these four grow light sources, LED lights are the most expensive, but you can generally get around 50,000 to 90,000 hours of use out of them. Which makes them more affordable in the long run because you don’t have to replace them as often. And the energy savings also adds up.

However, if you want to try out the latest in light grow technology, you should check out some of the best COB LED grow light products that are currently available.
