Philips Automotive Grade Quality products are designed and developed following strict quality-control processes, leading to consistently high production standards. All our products are best-in-class quality, which allows us to be an Original Equipment Manufacturer (OEM).
We use the highest quality raw materials to manufacture our products. At every stage in production, we test the bulbs to the highest specifications for improved quality and the safety of our customers.
Some competitors may not be able to prove their performance claims, both in terms of lumen output and product lifespan. They may indicate the specifications of the LED chips rather than the full bulb itself, for example:
- Lumen output: say an LED chip gives up to 1,000 lm. If the LED upgrade bulb has 8 chips in total, they might claim a total lumen output of 8 x 1,000 lm = 8,000 lm. But the lumen output cannot be calculated like this, it needs to be measured with specialist equipment.
- Lifetime value: An LED chip can usually last up to 30,000 hours at 25°C (room temperature). However, what matters is how the LED chip is integrated within the bulb, and how the generated heat is managed when the lamp is in use. These variables can change the lifetime of the LED chip (so a claim of a 30,000-hour lifespan could be misleading in an inferior product).
