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.
Why are COB LEDs better?
These are the biggest advantages of COB LEDs for growing: Higher light density: many small diodes in a tight space makes for a much higher light density, meaning you need less space to produce more light.
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 does COB mean on LED lights?
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 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.
Which is better COB LED or SMD LED?
Like the SMD, COP chips also have multiple diodes on the same surface. But the difference between LED light COB and SMD is that COB LEDs have 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 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.
What does SMD mean on 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.
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.
Which brand of LED lights are the best?

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.
Which led strips are brightest?
This is why higher power LEDs are called “high-flux.” Lumens are used to judge the brightness of a LED strip. The greater the Lumens, the brighter the light emitted by the LED light strip. The Lumen rating is usually indicated with a number followed by the letters “lm.”
|450 lm||40 W||6 – 9 W|
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.
