Calibre bulbs are pretty standard... The tint is pretty light so the output comes out only SLIGHTLY whiter. You will notice that if you stand far away from the car they will actually look pretty white. Not sure about the other brand you tried. Looks like you spent a bit of money already though.

Just so you know, to get the 'white' effect, you need bulbs with tints as dark (or darker) as what EKVTIR-T linked. Any lighter and it will only shift the light a little bit. But you will lose a lot of usable light with these bulbs. Often, to compensate for the loss of light, the bulbs are made to draw more power. This usually doesn't compensate enough and has the drawback of much shorter lifespan (a lot of the cheaper bulbs will only last you a few months). There are a few exceptions, such as the Philips bulbs which still have a fairly long lifespan and light comparable to the OEM bulbs. Don't expect a jump in light output though with any of these tinted bulbs (though they may give the illusion that they are due to the colour).
