looking for a white bulb, with brightness comparable or slightly better than stock halogen. what's the difference between blue vision ultra and hyper blue?

I COD this Blue Vision Ultra from him on Wed as well. Quite an efficient guy to deal with.

The light still contains a yellow tint during day time and doesn't really seems there is any difference with stock halogen, but looks whiter at night. For those who wants a complete white color bulb should got for the Crystal Vision 4300k, or Diamond Vision (with very obvious blue tint).

Edit: Even with a whiter temp, this bulb still is brighter than stock (my stock is an Osram).

Now then you sell the 4200K bulb, that's what I hope to get in the first place but ended up getting the blue vision ultra from you.
