Why is COB LED better?

Why is COB LED better?

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. The next time you are in the market for exhibit lighting, insist on COB LED technology!

Are COB LEDs more efficient?

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.

What is the difference between LED and 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. COB chips also only have 1 circuit and 2 contacts, regardless of the number of the diodes.

What is the purpose of COB light?

COB lights are essentially an array of LED chips that are tightly packed together and bonded to a substrate such as silicon carbide. In effect this creates one large LED chip that has excellent uniformity of brightness, thus making it ideal for photographers and filmmakers.

Which is better COB or panel light?

COB downlights provide a better light source. It achieves a more focused light and with the use of reflectors, the light beam can be controlled.

Is COB brighter than SMD?

Brightness But among different types of LED, the lumen differs. For example, SMD, it applies 50 to 100 lumen per watt, while the lowest measure of COB is 80 lumen per watt, higher than that of SMD. Therefore, lights with COB are brighter.

Are COB lights any good?

So there isn’t much to compare other than light distribution. While COB LEDS do provide an excellent light intensity, they’re not exactly the best when it comes to spread, because COB LEDs are a single-point light source (meaning all light comes from a single point in space).

Are COB lights good?

While COB LEDS do provide an excellent light intensity, they’re not exactly the best when it comes to spread, because COB LEDs are a single-point light source (meaning all light comes from a single point in space).

How efficient are COB lights?

When the chip is combined into the COB bulb, the efficiency of the whole bulb will drop a little, approximately 15% to 20% due to many factors like light beam angle, LED chip assembling, silicone gel, and power supply among others. So the whole LED COB bulb efficiency is approximately 130-140 lm/watt.

How long does a cob led last?

A COB LED has an average rated lifetime of 50,000 hours.

What is the best COB LED?

How long does a COB LED last?

Does a COB LED need a driver?

drivers are typically used in series wired systems. If you’re new to LED, I’d suggest starting with constant current drivers as they are far easier to work with and are generally better-suited for most LED applications.

How many watts COB LED?

COB (chip-on-board) or Integrated LED lighting is simply printed circuit boards with many low-wattage diodes directly mounted. For example, a “50W” COB LED may be comprised of 50 1W diodes, or 100 0.5W diodes.

Do COB LEDs need a resistor?

They do not have built in resistors or other current limiting. You must provide such. The dimmer looks like it just pwm’s the signal, and provides no current limiting. You can probably put them in parallel (modern led process control is good enough that leds from the same batch can usually be put in parallel.

What is the voltage of COB LED?

With an input voltage range of 90 to 305 VAC, the driver is capable of supplying up to 1.05 A to the COB LED (which, in this case, has a test current of 1.05 A and a maximum rating of 1.38 A) and will not be damaged by over-driving it.

How many watts 4×4 grow tent?

Just remember that one square foot of grow tent space needs roughly thirty-two watts of real wattage. According to research, a 4 x 4 requires around 512 watts, but the wattage can range from 500 to 650 watts.
