Philips X-treme Power H4 Upgrade Headlight Bulbs (2 x Bulbs) RRP £32.19 @ Amazon £16.90
H4 Philips X-treme Power +80% bulbs 12V 55W
Introducing the new world champion in high performance headlamp upgrades. Philips X-treme Power bulbs deliver up to an astounding 80% more light than standard halogens, yet they are fully road legal and come with the same quality and performance put into the lighting Philips sell to OEMs around the world. X-treme Power is a new must-have for tuners and high performance drivers.
Here's what Auto Express have said:
"Philips latest bulb was so new, we could not randomly select test samples, so couldn't include it in our assessment. Yet the performance of the pre-production unit was staggering. Even compared with the current benchmark plus 50 per cent bulbs, the difference was immediate and dramatic. Philips claims an 80 per cent improvement over standard units, but we think that is conservative."
"The results have been achieved in the same way as the 30 and 50 per cent lamps - by taking the allowed tolerances right to the edge. This time, though, as well as reducing the filament and burning it hotter, Philips has shrunk the glass casing."
"As a result, the gas pressure can be increased for better light output.
Benefits
80% more light on the road over a standard halogen bulb
Fully 'E' Marked and road legal

Winner of the Auto Express bulb test 2008 and accessory of the year
Who would by these?
Those who are after a quality bulb that produces the most light output on the road without converting to an HID Xenon system. Also those after a bulb that offers the highest quality and reliabilty from one of the worlds leading bulb manufacturers.
I know these are available for less than the RRP in many places, but this is a bargain. Fitted a set to my car recently and the difference is unbelievable.

They are simply to bring up the old H4 headlamps more in line with the industry standard today. If correctly aligned (and the driver doesn't leave the beam on in oncoming traffic...) They shouldn't be particularly dazzling.
As someone who drives old cars, they are a must at this price for improving safety.
Switched to Osram's Nightbreaker Plus 90% bulbs, which are cheaper, brighter, and are still running 12 months on :)
Well worth the money in my opinion, as they have probably saved me from a couple of hundred pounds worth of tyre damage.
Most modern cars have projector headlamps which throw a very tight beam, so these will only dazzle others if the headlights aren't correctly aligned.

I dont understand, what do you mean "incresaing the brightness in one area only..."
;)
What I mean is people that increase the brightness in front of their car to the detriment of other road users, i.e. full beam (often blue colour) and fog lamps on in a built up area.
They are much brighter than the older bulbs they replaced. I drive on country roads, with these dipped lights only. No need to use the full beam, which saves the messing with turning full on and off as you pass other cars.
Has anyone tried the LED headlights bulbs? You can get them on fleabay sent from hongkong, but do they shine enough light out?
