Why buy the Philips X-tremeUltinon gen2 LED W21W 6000K (Twin)?

As with Philips’ first generation X-tremeUltinon range, the X-tremeUltinon gen2 range continues to enhance both the brightness and style of your vehicle’s lighting, while lasting for many years to come. Avoiding the unattractive ‘dotted’ effect of so many inferior LED bulbs on the market, the X-tremeUltinon gen2 creates a crisp white projection that is broad, intense and equally diffused.

With an impressively high light colour temperature of up to 6000K, the X-tremeUltinon gen2 achieves a striking, cool white light that both looks stylish and yet feels comfortable to the eyes. Where such an improved, vivid light would generally sacrifice lifespan in a halogen bulb, the low-wattage LED design by Philips offers a powerful, yet economically sounder approach to lighting. Owing to this – and Philips’ resilient construction – the X-tremeUltinon gen2 offers a tremendously long lifetime of up to 12 years.

The X-tremeUltinon gen2’s impressive light output, style and life expectancy is due to the bulbs’ innovative design and meticulous construction. Making use of only Philips Automotive-Grade Quality materials, the X-tremeUltinon offers a robust yet sleekly designed bulb, capable of expansive illumination that is also able to withstand extreme shocks and vibrational damage. And by using the latest in heat-management and beam placement systems, the X-tremeUltinon gen2 offers enhanced accuracy while being highly defensive against high (otherwise potentially destructive) temperatures.

Achieve maximum style with minimal effort today with the Philips X-tremeUltinon gen2.

(These X-tremeUltinon gen2 LED bulbs are not ECE-certified as road legal and are intended only for off-road usage. Additionally, they may trigger a bulb error message to appear on the vehicle's on-board computer system / dashboard. This, along with potential flickering, 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.)
