What is 3w COB LED?
COB (stands for Chip On Board) feature a number of individual LED chips mounted together on an aluminum substrate, and covered with a silicone dome that seals them in and makes them weatherproof.
What is COB LED light?
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. For example, a 500 lumen COB LED array can be many times smaller and consume substantially less energy than a 500 lumen SMD or DIP LED Array.
Are COB LEDs better?
But the difference between LED light COB and SMD is that COB LEDs have more diodes. COB chips typically have 9 or more diodes. COB is known for better lumen-per-watt ratios and heat efficiency. This has a lot to do with the design of COB LEDs, and the cooling ceramic substrate of the chips.
What is the difference between COB and LED lights?
COB LED light source packaging technology is a direct chip package on the board, COB has improved light efficiency, improved glare effect of LED lights, and reduced light loss. With COB packaging technology, labor and manufacturing costs are 5% less than SMD. And life expectancy is much higher than traditional SMD.
Which is better COB LED or SMD LED?
Although a COB LED is efficient, an SMD LED has an even greater level of efficiency. That’s because more lumens are produced per watt. In other words, you’ll receive more light with less wattage. An SMD LED also produces a broader light beam, which means the light doesn’t need as large of a heat sink as a COB LED does.
Is COB LED waterproof?
heat lamp plant cob grow light 100% IP67 Waterproof and Dustproof: The highly water resistant feature is suitable for the high humidity working environment, especially for rainy or snowy days.
Is Cree better than COB?
Cree LEDs produce a fair amount of heat for a single chip but can disperse that heat easily. COB LEDs produce a similar amount of heat but as a harder time dispersing that heat. That means Cree LEDs may have a longer lifespan than COB LEDs depending on how much use they get.
Which light is better cob or LED?
What does Cree COB LED mean?
Chip-on-Board (popularly called COB), is an LED-styled system that features the direct mounting several LED chips on the top of a substrate to produce an LED system with a single module.
What is a Cree COB LED?
COB, or Chip on Board is a fairly new member of the LED family. Multi LED chips are packed closley together as one lighting module. And when it light up, it appears like more of a lighting panel than multiple individual lights if that makes sense.
