Why buy Philips X-treme Ultinon LED W5W 501 8000K?

If you’re looking to improve both the lighting and style of your vehicle’s interior, try Philips’ new X-treme Ultinon LED bulbs. Unlike some technologically inferior LED bulbs that are on the market these days, Philips X-treme Ultinon 501 LED bulbs produce a brilliant and uniformly diffused light with a blue tint, avoiding the cheap, 'dotted' effect of inferior LED bulbs in the market. What’s more, through Philips’ utilisation of their unique CeraLight ceramic technology, X-treme Ultinon bulbs offer an extremely durable bulb that can withstand high temperatures as well as vibrational damage, achieving a remarkably long life of up to 12 years.

Made to the highest quality of Philips Automotive-Grade Quality standards, the new X-treme Ultinon bulbs offer the very best in lighting design, guaranteeing you an easy installation and a powerful, precise light beam performance. Give your vehicle some extra comfort, some extra style and some extra light – for years to come.

(The usage of these bulbs in an exterior application is not road-legal and, in addition, may trigger a bulb error message to appear on the vehicle's on-board computer system / dashboard. This is a harmless side-effect owing to the difference between halogen and LED technology. Any such warning errors may be removed with the additional installation of a CANbus control unit.)

5 8k or 6k

These are supposed to be 8k but they match my Phillips HID 6k. I purchased 6k as well and used test elsewhere. Service was great. I'll be back for more!!

5 Perfect consistent and coherent 8000K with that Xenon blueish tint

I bought these bulbs in 8000K, in 6000K as well as their Osram equivalent in 6000K for parking lights. 6000K is exact Cool White; the 8000K is perfect exact Xenon effect/blueish tint white. Exactly what I wanted. Osram 6000K Cool White has some yellowish/greenish tint with that White. The tint is really faint. If Osrams are fitted on both sides one might not even see the tint. yet, since I had fitted Philips 6000K in one side and Osram 6000K on another the difference is prominent. My apologies to the Powerbulbs as had to return the unnecessary lights after testing!
