I tried them and discarded them !
I tried silverstars and did not like them. That Blue tint stuff is not good.... Cuts your available vision. I think the hi-beam is more narrowly focused so a small spot may appear somewhat brighter, but overall area is not as brightly lit for the driver. Perhaps other drivers notice more brightness when they are "hit" by that spot of light but who wants to blind other drivers? (they might become dangerous to YOU). Without real improved lenses you are wasting your money. The best you can do is be very sure you have a good headlight "aim" that places the light where you need it most. Also, aim your foglights properly so they help you while not blinding others.
Luck to you,
