The Philips lamps usually lead the market. Tests I've seen in the past put em in front for output and beam focus.
I'm the sure the Osram ones will be fine, a decent improvement on standard H4's and for the price better value.
Oh one of the Philips lamps I fitted to my car seven years ago has just failed. Not bad, the other one is still burning bright.
And of course remember don't touch the glass part of the lamp when fitting. Perhaps wear surgical gloves just in case you slip. Grease from even clean fingers will shorten the life of the lamp.
Good luck with those LED H4 lamps, I hope you don't expect to actually see where you are going with them?
