Why buy Philips X-treme Ultinon LED W5W 4000K (Twin)?

If you’re looking to improve both the lighting and style of your vehicle’s interior, try Philips’ new X-treme Ultinon W5W 501 LED bulbs. Unlike some technologically inferior LED bulbs that are on the market these days, Philips X-treme Ultinon LED bulbs produce a brilliant, natural-feeling and uniformly diffused light, so you can enjoy a heightened illumination that doesn’t damage or tire your eyes. 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 Philips CANbus control unit.)

Perfect

These replaced the crappy incandescent bulbs of my foot well lighting, door lighting and my focused reader lights on my BMW 335d Touring. Amazing build quality. The white is just right. No yellowness, and none of the fluorescent hospital vibes. Bright enough to make a noticeable difference, but not a burden on the eyes. Only negative point is you need to ensure polarity is correct, this can be done by putting them, removing and putting in another way until they light up.

Great interior bulbs

Used these to replace the interior and puddle light bulbs on B7 Passat Alltrack. Much better than yellow original bulbs. I thought that these LEDs would just switch off abruptly rather than fade out like the original bulbs. Pleasantly surprised to find that they fade out when they turn off. Worthwhile upgrade.

I used this to replace 5w incandescent bulbs in my car interior and rear number plate holder and am getting way, way more light output and a much nicer colour (4000K) without the heat. Watch the polarity: you may need to turn the bulb around to get it to work otherwise you might think the bulb is broken. Very glad I bought these.

A great product

I tried installing a 5000K W5W bulb in my car before. It was really bright and white (without a tint of blue). However, the light gives out an absolute white color. It's fatiguing for the eyes and does not provide a good contrast to the interior of the vehicle. The 4000K bulb is better, in my opinion, because it provides more contrast and easier on the eyes without sacrificing brightness. I admit that the 5000K may have a better light output in lumens but the difference is subtle and it is because of the tint of the light output. Comparing this to the stock halogen W5W bulb, this is on a different league. I highly recommend this to all car owners.

4/5

As per other's reviewer's observation, it appears that there are quite a few revisions of these bulbs. The ones I've purchased from Powerbulbs are: X-treme Vision LED T10 "CeraLight 360" 4000K August 2016, rated at 50 lumens (on box). SKU: 127994000KX2 Code: 39244930 X-tremeUltinon LED T10 4000K May 2018, rated at 45 lumens (on box). SKU: 127994000KX2 Code: 39594530 Regardless of the revisions, both appears to be performing well above the average incandescent bulbs in terms of brightness. Just be aware that there may be slight variant in terms of light output between revisions.

Okay bulbs

3/5

These bulbs put out 45 lumens, not the 50 lumens stated. It appears Philips has at least three versions of this bulb, this 45 lumen version, a 50 lumen version (with a silver instead of gold band) and a newer 45 lumen version in a different box (also sold on powerbulbs). This bulb is maybe twice as bright as a regular incandescent but the colour seems higher then 4000K, approaching the fluorescent tube white with a hint of purple, and it flickers slightly a few seconds after being powered. This seems to be normal for the bulb and it goes away quickly. Overall an upgrade over incandescent but not the amazing brightness and nice colour one would expect.

Quality Item as Expected

I had 2 pairs ordered to replace my interior reading lights, glove compartment, and boot lights. They look brilliant as expected but are just a tad bit whiter (still warm white) than Osram's LEDriving 4000K LED that i have in my footwell. You won't be able to tell the difference without a side-by-side comparison. All in all, it's a quality item and looks brilliant.

These really made the sidelights on our 2002 Skoda Fabia stand out - but then I read what I had overlooked on the website, that these are not road-legal. I can't see why they are not - they serve well the purpose of making the car clearly visible to oncoming drivers and if LED running lights are legal, why not these?

Philips Xtreme Vision 360

I hardly ever write reviews but am delighted with the bulbs and the support from powerbulbs.These LEDs are fantastic and the price can't be beaten, especially with the free delivery! The bulbs are extremely bright in comparison to stock bulbs and there is no flicker from them unlike other cheap LEDs. Also had the older Philips t5 led which were great but they only shone the light in one narrow direction, but the 360 version throws the light around in a much better way. Also purchased other bulbs from powerbulbs which failed after a short period of time and I have to say the customer support was A+ and they stood by their warranty. New bulbs fitted and they are perfect. Delighted!

This is the first led bulb that has a bright white light with a slight yellow tint, which looks whiter than oem but still keeps a factory look. Perfect for factory hid, but also goes well with philips 6000K ultinon hid, which has a slight yellow tint as well. These bulbs are bright, the 50 lumen claim is correct, and they have a very wide beam of light. Excellent in the license plate housings. These bulbs have a uniform beam color all the way around, unlike the osram leds that have a strong yellow ring around the edges and purple white in the middle.
