Best answer: Is cob better than LED?

Are COB LEDs efficient?

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.

What is better than LED lights?

XED or Xenon Energy Saving Discharge Lamps are superior to the most popular LED or Light Emitting Diodes in many ways. XED lights are better in terms of spectral contents, power consumption as well as total running life hours. … Research shows that the excess blue light of LEDs can cause harm to human health.

Are COB LEDs 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 is brighter 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. … The brightness here is 268 lumens at 2.5W of power consumption.

Do COB LEDs need drivers?

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.

How long do COB Lights last?

Using COB LEDs as Grow Lights

Light Type µmol/j (ppf/w) Lifespan
COB LED 1.8-2.5 30,000 – 60,000
Double-ended HPS 1.4-1.8 10,000 – 15,000
Ceramic Metal Halide 1.1-1.5 15,000 – 20,000
High Pressure Sodium 0.8-1.7 9,000 – 17,000

What is the most efficient LED chip?

2835 SMD CHIP

A newer led chip on the market named the 2835 led chip and is seen as even more efficient than 5050 led chip for 20% more light with using less wattage. It also has the benefit of not getting as hot because it is smaller.

Is 5W brighter than 3W?

So, to compare the difference between a 3W and 5W LED bulb accurately, you need to compare them at an absolute max of 60 to 65 percent of their total capacity, not the maximum rated wattage. And when you compare them on even terms, the 3W light actually produces more light with less heat and greater reliability.
