Paltik,
Compared to ordinary Halogens these perform better because of the farther light throw. You'll be disapointed if you're looking for "whiter" light color output. Actually whiter doesnt necesarilly mean it's brighter or you can see better. Check out the articles in this link by Daniel Stern the bulb guru:

You can even email him regarding these type of bulbs with 50% more light throw. There are two kinds so far in the market which are Osram Silverstar and Philips Vision Plus. These aren't hped up bulbs .. Yung hype talaga yung mga nabibili na superwhite with outrageously claimed higher wattage kuno pero in reality 60/55 pa rin.
I have noticed the difference between the silverstars and my stock halogen bulbs before pag byahe ko sa pauwi probinsya. Usually sa gabi may mga daan na wala man lang mga lamp post. The silverstars do their job nicely. Pag agulan din these bulbs are way better than superwhite bulbs.
Compared to HID bulbs syempre that's another story. HID bulbs have higher lumens compared to Halogens. kahit anong color temp pa ng HID.
