What is a COB LED Grow Light?
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 a wired to each other within the confines of a copper or ceramic board.
The many small LEDs work together to produce one light source.
Why Growers are Crazy for COB LED Grow Light?
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 that can be produced per watt that is 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 plants’ 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 frequently replace them.
A high quality LED lighting fixture lasts at least 30,000 hours. Even doubled ended HPS lamps have a life expectancy of only 10,000 hours.
Are COB LED Grow Light 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 simply pushed the price skyhigh.
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 are embracing 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 that you realize is that the crucial component of not only a plant’s growth but also 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 hotspot or low intensity areas.
Comparison And Differences Between LED Grow Lights
When deciding on which grow light will best fit your needs you will want to take the time to compare the various lights.You can weigh the pros and cons before deciding of COB lighting is your best option.
