Differbetween
It is simply the scale that differs. A COB is made up of many tiny LED diodes tightly packed onto a single chip to produce a single, powerful beam of light. A quantum board also has many LEDs on it, but those LEDs are more powerful and more spaced out. Essentially, a quantum board is simply a very large COB.

Are cob grow lights better?
Better light spread: since COBs are usually placed fairly far apart on large fixtures, they cover the plants below more evenly than a smaller light fixture that has to spread out from a central point. Efficiency: COBs give you more power per input watt and also product less heat.
What is COB mode?
Chip-on-Board or "COB" refers to the mounting of a bare LED chip in direct contact with a substrate (such as silicon carbide or sapphire) to produce LED arrays. COB LEDs have a number of advantages over older LED technologies, such as Surface Mounted Device ("SMD") LEDs or Dual In-line Package ("DIP") LEDs.
What is a COB LED?
Relatively new to the LED market, chip on board (COB) LEDs offer many advantages over the standard options. COB LEDs are basically multiple LED chips (typically nine or more) bonded directly to a substrate by the manufacturer to form a single module.
How long do quantum boards last?
Aside from the allure of their newer technology, they are great at growing cannabis and they last a very long time compared to some other grow lights. In fact, the ones we recommend can last 100,000 hours; that's over 14 years if you harvested every 3 months!
Is cob better than SMD?
But the difference between LED light COB and SMD is that COB LEDs have more diodes. COB chips typically have 9 or more diodes. ... Another aspect of the COB vs SMD LED Lights difference is in the use of energy. COB is known for better lumen-per-watt ratios and heat efficiency.
Which is better Cree or COB LED?
The CREE LED lighting system has a larger size and a PCB area that is wider than its COB counterpart. Both of the LEDs generate large quantities of heat when they are both being used. ... By being wider and bigger, CREE can dissipate a higher volume of heat into its environment. This simply means that it is longer-lasting.
Are COB lights dimmable?
Dim-to-Warm is COB LED which works like halogen lamp when dimmed. Its specialty is that when you dim it the color temperature gets warmer. Usually dimming does not affect the color temperature of the LED. ... It's perfect for space where you want to have dimmed and warm toned atmospheric lighting.
Do COB LED need heatsink?
The abbreviation COB refers to Chip On Board. ... In the case of COB LEDs, it is possible to directly attach a COB LED to a heat sink (see Figure 2). As a result, COB LEDs do not require PCBs in order to install LEDs into a luminaire and the subsequent reflow process is no longer necessary.
What is a cob flood light?
COB ( chip on board ) LED products are slowly starting to seep into the market , it is set to take the whole industry by storm soon. A chip on board LED is basically a LED chip diode built directly on the the circuit board.
How hot do COB lights get?
2 LED junction's temperature can easily exceed 250 degrees Celsius in a matter of seconds.
What does SMD mean for LED lights?
SMD means surface mounted diode. This is a better technology than the first generation DIP LEDs. The SMD type LEDs are mounted on an aluminum substrate and enveloped in an epoxy resin.
Do COB LEDs need drivers?
3. LED Drivers. LED drivers are the handy little boxes that take the power from your electrical outlet and convert it to a form that the COBs can use. The electricity coming from your outlet is alternating current (AC), and this does not work for COB LEDs – they require direct current (DC) instead.
