German automotive giant Volkswagen's electric SUV ID.4 uses in-car lights to communicate with passengers. Placed under the windshield, 54 LEDs communicate with passengers using both lighting patterns and colors.
What Is the Difference Between Philips Essential and CorePro LED Bulbs?
The most important difference between Philips Essential LED bulbs and CorePro LED bulbs is the luminous efficacy. Luminous efficacy is the lumen of the lamp per watt. In other words, it is the quantity of light that produced per watt. A product with higher efficiency factor is more effective. So, it gives more light than the electrical energy it consumes.

Philips Essential LED bulbs have a life span of 10,000 hours, in other words, they have a lifespan of 10 years in 2.7 hours daily. Similarly, Philips CorePro LED bulbs have a lifespan of 15,000 hours, that means 15 years.
Another difference between the two light bulb series is on/off, in other words the number of switching. Essential series of lamps have an on/off lifespan of 20,000 times, while CorePro series can rise up to 50,000 times.
The most important difference between Philips Essential LED bulbs and CorePro LED bulbs is the luminous efficacy. Luminous efficacy is the lumen (luminous flux) of the lamp per watt. In other words, it is the quantity of light that produced per watt. A product with higher efficiency factor is more effective. So, it gives more light than the electrical energy it consumes.
In both models, when the products in the power range close to the 3000K color temperature of LED lamp are analyzed, CorePro series stands out. Philips Essential 8 W LED bulb has 610 lumen of light output, it means that the efficiency factor is 76.25 lm/W. Philips CorePro 10.5 W LED bulb has 1055 lumen of light output. When calculating according to these values, we get 100 lm/W value.
As a result of these calculations, Philips CorePro LED bulbs stand out in terms of luminous efficacy and product’s lifespan. For this reason, if your budget is enough, it is better to choose this series.
