My Philips extreme are apparently winners in the H7 sector, but just also rans along with the Halfords branded lamps in the H4 sector. All my lamps are H4 :'( However I can tell you they are still way better then standard lamps and they burn for years on end.
Auto express says the best you can get are Osram Night Breaker Plus followed by RING Xenon Ultima
Check the menu on the left for each lamp review - http://www.autoexpress.co.uk/car-mainten...lbs-tested
A pair of those top Osram lamps comes in at just over 17 quid on Amazon, the RING ones about the same price. So 8.50 each.
But at 20 quid each, Halfords are having a laugh.
