Have you heard that plants grow better under COB LED grow lights?
What is a COB LED light? COB stands for “Chip-on-Board”. The LED chips are mounted onto the circuit board that creates the LED arrays. The construction of COB LED lights requires fewer components, thereby maximizing LED chips’ usage within the circuit.
The broad spectrum sky-high Color Rendering Index (CRI) of the COB is usually well over 80, making it the best grow light on the market.
Also, with COB LED, grow light space is never an issue. If you are using a grow tent or small room, then there is no comparison to the COB lighting fixtures’ compact size.
Undoubtedly, COB grow lights produce full-spectrum lighting that should meet all of your plant’s needs. COB grow lights also come in a convenient package size geared towards any indoor growth space’s small space needs.
If you seek one of the best indoor grow light systems, you won’t be disappointed with the COB LED grow light.
A COB grow light is a compelling, full-spectrum lighting choice perfect for all stages of a plant’s life cycle. Also, unlike traditional LED lights, which tend to be large, the COB’s compact size is better suited for indoor gardening and grow tents.
Here in this article, we’ll explain how COD LED grow lights increase Plant Growth, Efficiency, and Yield. This guide will also help you decide the best cob LED grow light to buy for your grow space’s size.
We have tested five of the most popular COB LED grow light systems to determine the most efficient, what has the most efficient wavelengths, and how much they cost to buy and run.

The light’s lumens are 15 to 30 percent brighter than comparable lights, but you can easily dim the light output down and tailor it for your plants’ custom growth needs.
What is a COB LED Grow Light?
As we went over before, COB stands for “chip-on-board”. The term describes the multiple LED chips that are mounted onto the light’s substrate.
They are arranged to form a single module.
Multiple small LEDs are packed and wired to each other within the confines of a copper or ceramic board.
The many small LEDs work together to produce one light source.
When the COB LED is energized, it has the appearance of a large lighting panel with a multitude of small individual lights.
All of the rays flow together to create a singular, bright light.
Why are Indoor Growers Excited about COB LED Grow Lights?
There are numerous reasons to choose to use COB grow lights for all of your indoor gardening needs.
Efficiency is measured in µmol/j, which is the amount of photosynthetically active photons produced per watt consumed at the wall.
The process is interpreted as µmol per watt. The efficiency of a COB LED is about 130-140 lm/watt.
Plants require adequate light to grow. The COB grow light offers stronger lighting than other light sources, even standard LED grow lights. Many growers consider COB LED to only be behind HPS in quality of light output.
Modern LED lights, such as COBs, have the widest spectrum wavelengths. Some bulbs feature a 12-color spectrum that includes IR (infrared ray) and UR (ultraviolet ray) to meet all of your plant’s light requirements.
Low Heat Output
Heat ventilation in COB LED grow lights are ideal. The LEDs produce strong light without emitting a great deal of heat.
Some high-end COB grow lights have a quality substrate that boasts fans and drivers to reduce heat output even more.
COB LEDs produce an abundance of brightness, but they are relatively compact in size. The light’s small size makes it ideal for a small indoor grow room or tent.
LEDs have the highest usable lifespan of all grow lights. Yes, the initial investment might be a bit more costly, but the lights pay for themselves because you do not have to replace them frequently.
A high-quality LED lighting fixture lasts at least 30,000 hours. Even double-ended HPS lamps have a life expectancy of only 10,000 hours.
Are COB LED Grow Lights Worth The Money?
Does the high cost of COB LED grow lights concern you?
Yes, they are initially expensive to purchase when compared to other similar grow lights.
You might be wondering if they are truly worth the expense or if the hype surrounding them has pushed the price sky-high.
Undoubtedly, you do not want to spend an arm, and a leg on expensive grow lights that you might not need.
However, rest assured that COB LED lights are worth every penny.
In time, they will pay for themselves in cost savings and robust harvests.
Depending on the manufacturer, the lifespan of the COB LED ranges from 30,000 to 60,0000 hours. No other types of grow lights even compare.
The longest lifespan of the ceramic metal halide light is still 20,000 hours. A double-ended HPS is only 10,000 to 15,000 hours.
The Superior Light Quality of COB Grow Lights
Serious indoor gardeners embrace COB grow lights not just because of their excessively long lifespan but also because they render superior light quality that surpasses other grow lights.
If you are serious about indoor growing, then the first thing you realize is that the crucial component of a plant’s growth and its ability to flower is the quality of light.
COB LED broad-spectrum lighting offers amazingly high CRI (usually over 80) is superior to any other grow light. All COB manufacturers offer 70 CRI broad spectrum chips in their lighting.
The chips easily go up to 97 CRI. This means that the lights render no purple, excessive orange, red, or yellow, but instead, they display high-quality white lighting that shows true realistic colors just like natural sunlight.
Plants grown under COB have the ability to photosynthesize better and create robust flowers for a high yield.
HIB and COB Technology
HIB lights have long been king in grow rooms around the world. However, times are changing, and now COB has taken center stage as the favored lighting choices for everyone, from large-scale commercial cultivation outfits to small backyard growers.
LEDs can effectively produce better photons than HID technology. Without a doubt, COB LEDs will always outperform HID technology by producing exceptional lighting that evenly covers your plants’ canopies.
HIC and COBs function as single-point light sources, but the COB lights are far easier to handle and position, so you are guaranteed outstanding light coverage.
Unlike with HIDs that use a single light source, COBS can easily be fashioned at various angles and spacing to create uniformity.
Such placements help you avoid hotspots or low-intensity areas.

What Is The Difference Between LED And COB LED?
Many people become confused and think that COB LEDs are not LEDs. However, they are the same technology but just packaged differently. COB LEDs offer fantastic light intensity and spread because of the design.
Indoor gardening allows you to cultivate plants year-round. However, one of the essential components of producing a bountiful harvest is having the correct lighting.
A COB LED grow light is an efficient and modern lighting choice for grow rooms.
If you seek a grow light that truly mimics the sun, you won’t be disappointed with the energy-saving COB LED grow light.
These lights also last for years and provide all of the various lights required by your indoor garden to flourish from seedling to harvest.
