like the Osram Cool Blue Intense, the price paid is much higher than the true value of the bulbs, the descriptions are much more rewarding than the actual effectiveness of Xenon bulbs = the effect is non-existent, and the light is hardly more white than halogen bulbs of origin, as to the extra brightness, I do not know where it went but in any case, I see little better. So, do not get carried away on these items bling bling, the price is not worth the candle
