A chip-on-board or “COB” is the mounting of a bare LEDs chip in direct contact with a wafer to produce an array of light emitting devices. There are a number of advantages to using COB LEDs over older technologies.

What is the difference between LED and COB?
There is a difference between the two types of light. The COB chips have a lot of transistors. COB chips only have one circuit and two contacts, no matter the number of the diodes. COB has better lm-per- watt ratios.
What is better COB or LED?
Today’s most advanced technology is chip-on-board LEDs. COB LEDs are brighter, consume less power, and produce a better quality beam of light than older technologies found in most other trade show lighting today.
Are COB lights better?
COBs cover the plants below more evenly than a small light fixture that has to spread out from a central point. The efficiency of COBs is that they give you more power and less heat.
Are Cree LEDs good?
We like to think that the best of the CREE LEDs are the same as the Apple products. A crisp, but low-glare output can be provided by CREE’s.
Do COB LED need heatsink?
COB LEDs can be directly attached to a heat sink. COB LEDs have low thermal resistance and no PCB are required for installation, which makes them a better heat dissipation model.
What is better LED or COB?
COB LEDs are brighter, consume less power, and produce a better quality beam of light than older technologies found in most other trade show lighting today. If you’re in the market for exhibit lighting, make sure to use COBLED technology.
Are COB LEDs efficient?
The efficiency of the whole bulb will be reduced by 15% to 20% when the chip is combined into it. The wholeLED COB bulb efficiency is between 130 and 140lm/ watt.
What is the difference between SMD and COB LED?
The lamp bead is attached to the surface by a light- emitting device. COB has improved light efficiency, improved glare effect, and reduced light loss by using a direct chip package.
Which is better SMD or LED?
One of the biggest improvements is that SMD spotlights offer a higherlm output for a lower energy consumption. They work on the principle that larger and smaller SMD LEDs produce more light.
What is the most energy efficient LED grow light?
HLG 650R grow light is the best option when it comes to choosing the most energy efficient and value for money LEDs. The grow light is perfect for a 5*5 grow tent and can be used to grow a single plant or clone a plant.
What does COB light stand for?
Are COB lights any good?
COB LEDs are a single point light source, meaning they are not the best when it comes to spreading light.
How hot do COB lights get?
Up to 28.8 Watts of electricity at 6V can be utilized by 2 LEDs, which can create a lot of light and heat. The XHP70 did not have any thermal management efforts. The junction’s temperature can easily go up to 250 degrees Celsius in a matter of seconds.
Which is brighter COB or SMD?
An even greater level of efficiency can be found in an SMD light emitting device. The lm are produced at a higher rate. You will get more light with less power. A larger light beam is produced by an SMDLED, which means it doesn’t need as large of a heat sink as a COBLED.
Which is better cob or SMD?
Because the light source produces higherlm per watt, SMDs are more efficient than COBs. A larger beam of light is produced by them.
What is SMD in LED light?
A surface mounted device is called a SMD. The technology is better than the first one. The LEDs are mounted on an aluminum surface and coated with an epoxy resin.
Which is better Cree or COB LED?
There is a fair amount of heat produced by a single chip but can be dispersed easily with the help of ree LEDs. The same amount of heat can be produced by COB LEDs but it is harder to distribute. Depending on how much use the COB LEDs get, they may have a longer lifespan than the Cree LEDs.
Do LED lights really save money?
Less heat in the house. The traditional bulbs emit more heat than the LEDs. Consumers can save as much as $75 a month by using Energy Saver, an online resource that helps consumers save money.
