*Help!* Changing to Philips X-Treme Power (+80%) headlight bulbs

Hi everyone,

I was reading about these new bulbs,
It says they burn brighter by reducing the bulb size to increase the gas pressure.

My questions are these(!):

1.) As they burn at a higher temperature is there any possibility that it might scorch or blacken any of the glass/plastic or any part of the reflectors?

2.) What bulb size is needed for the dipped headlights?

3.) Does anyone have any idea how long they last for with typical use?

4.) Do they work the same with headlight adapters when driving abroad.


Many thanks in advance for any answers to the questions!

Hi Mark
As I understand it, they burn brighter because the filament wire is thinner. Heat output is related to the bulb wattage and on the Xtreme bulbs, this is the same as standard so they won't run hotter than your current bulbs.

Dipped bulb size is H7 (for info, main beam is H3

I have the Xtreme bulbs and they have lasted 2 years so far. I'd guess they will have about half the life of a good quality standard bulb

As with any high output quality bulb the beam pattern does not really change so your headlight adapters will work the same

Cheers Spike
 
I've gone through a lot of different (always well known brands) H7 bulbs since I have them on always and everytime I change one, no matter what brand or model, standard or extreme++silverstar whatever, the new one is always stronger than the old one. It seems, that changing the bulbs for new ones is the best upgrade.
 
i wasted a few hours reading which bulb is best, which one wont set fire to your headlight blah blah blah then realised I was broke anyway and found 2 for £20 at halfords for their own brand h7 bulb. popped them in and what do you know, loads of light.
The thing that made the biggest difference to my night driving was getting my eyes tested and changing the very scratched lenses in my spectacles. Now that made a huge difference. :)
 
As spike pointed out, it is the wattage. If anything, these are more efficient bulbs which translates more electricity into light than heat, so they might even be ever so slightly cooler.

The other typical worry is the extra amount of UV that may age the plastic lense. But I would expect philips to have done their homework or they should face a class action lawsuit :) I would use them with no worries.
