It is still slightly on the yellow side of white so if you're after the neutron star effect then you might want something else. Given the similar pricing between these two models, it seems logical to choose the Xtreme Vision 130%.

Just as with the performance version (below left), we suspect build problems with this pair, because their performance proved to be no match for not just the X-tremeVision, but also stablemate Ring’s standard bulb. Designed to be easily installed in compatible vehicles, so drivers with maintenance experience will be able to upgrade compatible headlights with ease. However, it's recommended that you get your new Philips LED headlights installed by specialist mechanics – they will make sure you're ready to go. This helps you recognise obstacles and any potential dangers earlier than with most other halogen headlight lamps.Running both tests at the same time, although in different headlamps, gave us a chance to see just how big an advance HID was over halogen when it was introduced over 20 years ago. With its optimised high-precision filament geometry, up to 13 bar high-pressure gas filling, high-precision coating and high-quality UV-Quartz glass, Philips X-tremeVision headlights set a new milestone in automotive lighting. Though it is worth remembering that where this is a significant increase in light output, it does come at the cost of a reduced bulb lifespan – 250 hours compared with the X-tremeVision Pro150's whopping 450 hours.

Philips Automotive-Grade Quality products are designed and developed following strict quality control processes (including applicable ISO norms), leading to consistently high production standards. Our figure of merit (FOM) was also calculated using levels at 50 metres in front of the car on the kerb and in the centre of the road, plus twice the hard-to-reach 75-metre roadside mark. All of which means that the RacingVision GT200 grants you not only huge amounts of light and safety, but also can decrease stress and anxiety while driving in the dark.

This makes two wins on the trot for the RacingVision GT200, following its single-filament H7 victory in our last test. The Sonicare brush head replacement subscription is all about bringing convenience to your healthy smile. While the halogen bulbs are built to the same design, the Osram had a different ballast to the Ring, which may be a factor in the performance gap. Given the huge success of these two industry favourites, it's no surprise that their new, refined successors offer an exceptional light. If you’re in the market for a budget-friendly headlight bulb with a decent lifespan and a substantial beam, then I see no reason not to suggest Xtreme Vision.
