- Buying Guide for COB LED Grow Lights
The most recent craze among indoor growers is the COB LED grow light. COB, which stands for chip on board, is a technology that allows for many LED chips to be placed on one lighting unit. COB lights consume less power, are brighter, and have a higher light output than older LED lights using technologies like SMD and DIP.
COB LED grow lights have replaced traditional MH and HPS grow lights which operate at a high temperature and have a high energy consumption.
As indoor growers, there’s one thing we know for sure: the healthy development of plants is highly dependent on light. COB LED grow lights provide the best illumination for plants to bloom and produce high yields.
But there are so many COB LED grow lights, how do you choose the best one? We know it can be quite confusing to make a choice with so many options available. That’s why we’ve vetted and chosen the top COB LED grow lights.
Go through our list and choose the most suitable one for your needs.

Buying Guide for COB LED Grow Lights
When deciding which COB LED grow light to buy, there are important factors to consider and questions to ask. This guide will give you clarity and help you to decide which light is best for your specific requirements.
Here’s what to look for.
1. Full Spectrum
For plants to grow well, they require a particular range of light spectrum. Outdoors, natural light from the sun provides plants with a full spectrum for their growth. Indoors, LED grow lights provide plants with optimum light wavelengths. This optimal range is commonly known as PAR (photosynthetically-active radiation).
This spectrum has wavelengths between 400nm and 720nm. Plants typically use red light (620nm-700nm) and blue light (400nm-500nm) wavelengths in the highest concentrations. For this reason, the performance of COB LED grow lights should be measured in relation to PAR instead of lumens. A handy device called a PAR meter can help you measure the PAR output of your grow light.
2. The Size of Your Grow Area
If your grow area is 5X5ft, a COB LED grow light with 3X3ft coverage won’t be able to provide sufficient light to your plants. Your plants should be well illuminated by the light in order to grow and flourish.
3. Ultraviolet (UV) Light
Most grow lights on the market have very few chips with a UV spectrum for valid reasons. A high amount of UV light can be detrimental to the plants, damaging their physiological processes and endangering human beings as well. Most grow lights feature a small amount of UV which is safe for plants. UV light can make plants very potent.
4. Dimming Feature
COB LED grow lights that are dimmable allow you to adjust the light depending on the growth stage of the plants. As they germinate, the light can be dimmed to minimum to support growth at that stage. Very bright light at this stage can slow down growth and damage plants.
As the plants grow, the light can be increased at each stage because they can tolerate the brightness without any risk of damage to their growth.
5. Cooling System
All COB LED grow lights feature a cooling system, and rightfully so. But cooling systems are different. Choose a light with an in-built aluminum heat-sink, powerful fans, an air outlet and an inlet. These keep the light cool and prevent overheating, which could damage it. Also, the atmosphere around the plants remains cool and their growth process is not affected.
The prices of COB LED lights differ as night and day. You might be tempted to get a cheaper light, but will it meet your particular needs? Look for a light that offers the best value for money.
