Which is better SMD or COB LED?

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.

Is cob better than SMD?

Different light source quality

Compared with smd, the illumination is more uniform, there is no halo, the angle beam of COB is large and easy to adjust, there is no spot light or glare.

Which is better SMD or LED?

One of the biggest improvements is that SMD spotlights offer a higher lumen output for a lower energy consumption – making them more powerful and energy efficient than older LED lights. This is because they work on the principle that fewer and larger SMD LEDs produce a greater lumen output.

Are COB LED grow lights better?

But COB isn’t just known for its compact size, it also has more light intensity, and advantages than traditional LEDs and other grow light types. … Budget & easy-to-use COB LED grow light greatly suited for veg plants. Better combined with other lights for higher intensity.

What is the difference between COB LED and SMD LED?

The SMD LED light source is a single patch LED lamp bead with a light-emitting diode directly attached to the surface. 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.

How long do COB LEDs last?

Even if the initial investment is higher, a quality LED fixture will last AT LEAST 30,000 hours.

Which is brighter cob or LED?

Simply put, COB LEDs are brighter, consume less power, and output a higher quality beam of light compared to older LED technologies found in most other trade show lighting today.

What does SMD mean in LED bulbs?

SMD means surface mounted diode. This is a better technology that the first generation DIP LEDs.

What is the best SMD LED?

What is the Best SMD Chip?

  • 3528 SMD CHIP. The 3.5mm x 2.8mm chip is one of the most popular, due to its cost effectiveness and the fact that it doesn’t give off much heat. …
  • 5050 SMD CHIP. 5.0mm x 5.0mm are known as having ‘tri-chips’ simply meaning that they have 3 LED diodes in one housing. …
  • 2835 SMD CHIP. …
  • 5630 SMD CHIP.

What is the brightest type of LED?

What is the brightest LED type? Yes, as you can see by the table above, 5630 LEDs are by far the brightest, but it is not due simply to a larger lighting surface. There are other factors that go into the output of an LED diode (measured in luminous flux/lumens).

What does COB mean in LED lighting?

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.

What is the best LED grow light 2020?

Gavita Pro 1700e Gen 2 LED Grow Light

The Gavita Pro is already the most efficient LED on the market, and also one of the most powerful. It produces 1700 µmol s-1 PAR and pulls 646 watts from the wall. It works incredibly well in commercial grows and greenhouses and carries a manufacturer’s warranty of 3 years.

Are COB LED 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.

Are blue LED lights bad for you?

Research shows blue light exposure may lead to age-related macular degeneration, or AMD. One study found blue light triggered the release of toxic molecules in photoreceptor cells. This causes damage that may lead to AMD.
