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.)

Philips X-treme Ultinon LED W5W 501 4000K (Twin)

5 T10 led

Perfect fit for my Prius interior lights.Thank you.

Philips X-treme Ultinon LED W5W 501 4000K (Twin)

4 Decent bulbs, just not 50lm as advertised.

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.

3 Okay bulbs

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.

Bought these to replace my interior globes. These things light up the interior giving great clarity. 110% better than the factory globes.

5 Worth paying the extra...

I purchased a pair of own brand LED replacement bulbs from a well known car retailer. Although they looked the same size, they were a fraction larger in diameter and wouldn't fit my vehicle. These arrived today and they fitted my vehicle perfectly. They appear well made and produce a bright white light, without looking aftermarket.

5 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.

5 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?

5 Philips 194/168/T10/W5W L.e.d

I had been purchased Philips W5W L.e.d in 4000K,6000K,8000K frequently since 2015 from Powerbulbs. ①Standard / stable colour temp. compatiable with same l.e.d product line(Philips 6000K H8,H11,H16 l.e.d Fog moledule). ②4000K could give soft & comfort view. ③8000K could satisfy Japanese brand H.I.D users to blend in specific colour temp. ④50 lumens are enough without "over bright". ⑤Good & reasonable pricing from Powerbulbs

5 Great bulbs

I bought these bulbs as replacement/upgrade of the regular W5W for my Smart Fortwo. The 4000K pump out tons of light and colour seem just like the regular W5W. The 6000K is a little too blue to seem originals. I would recommend them without a doubt.

5 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!

5 Better & improved

I had the first Philips W5W 4000K lamps in the 14' Fiesta & they were very good. These are better! In the headlamp the new lamp shines sideways & reflects off of the chrome internals & they look just great from ahead & the side too. I've Osram nightbreakers on dip beam & they're a good colour match, not white/yellow. And I've just bought another pair for the focus, NICE!

5 Finally an oem color led

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.

5 Philips W5W Led's

Excellent service from Powerbulbs. Posted to Australia very promptly received within 10 business days, great work. Using the W5W's as parking lights in an older vehicle they make up for the reflectors that are past their prime.

5 Good Bulbs and Service

These bulbs are well built and will light up your area well. Firm fit in the socket, not like those cheap eBay bulbs. It’s a whitish yellow. You can match your 4300K bulbs with these LED. If you have an orange side marker, these bulbs will make that area a bright yellow. They will not match the Phillips XV 4800K D2S HID bulbs. PowerBulbs is a fast and accurate company. They also provide discounts from time to time, with a 10% discount for returning customers. Take advantage of those discounts.

5 Ffinally with the lens

hm.....I was using Osram 4000k LED. That time, Philips does not have the T10 led with front lens like this 360 version. (an older version of Philips t10 led do have front lens). so thought of to give it a try with this 360. I would say, the results is the same as OSRAM. in terms of brightness and color. So... there you go.
