Which is better COB or 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.

FAQ

Q: What color temperatures are available with e39 LED corn bulb?
A: Color temperature for light bulbs is measured on the Kelvin scale. LED Bulbs come in a variety of colors, but the most common are in a range from 2700 Kelvin to
7500 Kelvin. The unfortunate thing is that the only consistent measurement is the Kelvin scale, Many manufacturers like to use terms like Day White, Natural White,
Warm White and Cool White, but there is not a standard that defines a Kelvin temperature to associate a color temperature with those terms. The warmer the light,
the more yellow tones, the cooler the light, there are more blue tones.
2700 - 3200: Warm White
4000 - 4500 Natural White
5000 - 5500 Day White
6500 - 7500; Cool White
Its important to note: at home we use Warm White bulbs, in the office we use Natural White and in the Warehouse we use Day White. We rarely use or even sell Cool
White LEDs.

Q: Will the light levels decrease over the life of mogul base LED bulb?
A: Yes. They will fade as the bulb gets near the end of its normal operating life. But it is very gradual and hardly noticeable. This is called Lumen Degradation and is
denoted as L70. L70 is the amount of time the light takes to get to 70% of the initial lumen output.

Q: What is the most common reason e40 base LED bulb fail?
A: Heat Heat is the enemy of electronics, the hotter it is, the shorter the light. However, with good design, our bulb heat dissipation is good, so lifespan is long.
